    The invention relates to a sliding bearing element comprising a supporting layer and a sliding layer, wherein the sliding layer of silver or silver with a maximum content of other metals of 5 wt .-%, selected from a group consisting of Cu, Sb, Mo, Co , wherein the sliding layer has a microstructure with grains and has a sliding layer thickness.
    The invention further relates to a method for producing a sliding bearing element comprising a supporting layer and a sliding layer having a microstructure with grains, the sliding layer having a sliding layer thickness of silver or of silver with a maximum content of further metals of 5% by weight. will be produced.
    The trend towards increased power densities in the development of engine and engine generations places increasing challenges on the development of wear-resistant running layers. Often, this wear resistance is coupled to the requirement for high dirt compatibility and good-natured inlet behavior. Another trend in material and process development is to move away from environmentally hazardous materials or processes, while maintaining or exceeding the tribological and mechanical properties of existing conventional plain bearing materials.
    In order to comply with these developments, the necessary properties of a plain bearing are divided into several layers in plain bearing technology. As a result, the individual layers can be optimized in terms of their property profile.
    But there are also plain bearings with so-called gradient layers known. Here, a property, in particular the hardness of the layer, is varied over the layer thickness. As a rule, this takes place via the formation of concentration gradients for an alloy constituent. It can thus be achieved, for example, the layer thickness of the slide bearing, the excretion of different Mischpha-sen or intermetallic compounds, which in turn lead to different hardnesses within the overlay. However, the disadvantage here is above all that intermetallic compounds are generally brittle and thus represent a risk for the breakage of the sliding layer.
    The present invention has for its object to provide a sliding bearing element or a method for its production, which meets the above-mentioned requirements for the higher power density of a motor or an engine.
    The object of the invention is achieved in the slide bearing element mentioned above in that the microstructure on the overlay thickness of a globular Habitus of the grains in the vicinity of the support layer closer second surface of the overlay in an at least approximately stem habit with a longitudinal extent of the grains in the region the support layer more distant first surface of the sliding layer changes.
    Further, the object of the invention with the above-mentioned method is achieved, in which the temperature is changed during the production of the sliding layer, and thereby the microstructure on the sliding layer thickness of a globular habit of the grains in the vicinity of the support layer closer second surface of the sliding layer is changed into an at least approximately stem-like habit with a longitudinal extent of the grains in the region of a first surface of the sliding layer which is more remote from the supporting layer.
    The advantage here is that the sliding layer relatively easy from only a single metal - the maximum of 1 wt .-% further metals are common impurities of silver can be produced, and this sliding layer still shows a good run-in behavior. The sliding layer can therefore serve both as an inlet layer for starting the operation of the slide bearing and as a sliding layer per se after the running-in phase during normal slide bearing operation. The one-metal construction eliminates the formation of intermetallic phases. Due to the additional functionality "running-in layer" of the sliding layer eliminates the need for an additional layer to be applied for this purpose, whereby the Gleitla-ger element is relatively simple and accordingly the process for producing the sliding bearing element can be made simpler. On the other hand, the sliding layer through the globular grains is also correspondingly hard, whereby it can meet the high demands on the wear resistance in engines or engines. In other words, the sliding layer has a corresponding embedding capacity for dirt particles in the region of one surface and the required fatigue resistance on the other surface, although it consists of only a single metal or an alloy with a maximum of 5% by weight of at least one further metal consists.
    According to one embodiment variant, the sliding layer can have a sliding layer thickness between 10 μm and 100 μm. Below 10 μm, it is difficult to sufficiently image the bifunctionality of the sliding layer. On the other hand, a further increase in the sliding layer thickness above 100 pm does not bring any significant improvement with regard to long-term stability.
    According to a further embodiment variant of the sliding bearing element, it can be provided that the columnar microstructure extends from the first surface of the sliding layer to a depth of the sliding layer of at least 10% and at most 95%. It is thus achieved that the sliding bearing element retains its properties of lubricity and embedding capacity for dirt particles over a relatively long period of time. With less than 10% layer thickness of the globular portion of the grains, the softer layer formed therefrom from the columnar grains no longer receives sufficient support. On the other hand, with more than 95% layer thickness of the globular portion of the grains, the sliding layer already becomes relatively hard, as a result of which, after the start-up phase, the abovementioned properties are already reduced within a short time.
    It may further be provided that the sliding layer is disposed directly on and connected to the supporting metal layer, whereby the supporting effect for the stem grains can be improved by the globular grains directly with the supporting metal layer. It can thus be awarded as a result of a thicker sublayer with the grains with the stem habit a longer life. In addition, the direct arrangement of this sliding layer on the support layer also causes a simplification of the process by reducing the process steps for forming the layer structure of the sliding bearing element.
    To further improve the above-mentioned effects with respect to running-in and running behavior during normal operation of the sliding layer, it is advantageous if the grains with the longitudinal habit are oriented at least approximately perpendicular to the first surface of the sliding layer, or if the longitudinal axes of the sliding layers are oriented Grains differ by a maximum of 30 ° from this vertical orientation.
    An improvement in the above-mentioned effects with respect to running-in and running behavior during normal operation of the sliding layer could also be observed if the longitudinal extent of the grains having the columnar microstructure corresponds to at least twice the width extension of the grains having the columnar microstructure. With this configuration, the grains with the stem habit in the circumferential direction and in the axial direction of the Gleitla-gerelementes better support each other.
    In order to form an improved bonding zone between the support layer and the sliding layer or between the latter and the underlying layer of the sliding bearing element can be provided that a mean diameter of the grains with the Globularen Habitus a maximum of 20% of the length in the longitudinal extension of the grains with the stem habit. Due to the finer grains, the sliding layer area with the globular grains can also have a higher hardness and thus a better long-term behavior with regard to strength and wear resistance.
    According to one embodiment variant of the method, provision may be made for the temperature to be increased during the production of the sliding layer. It can thus be easier to obtain the formation of the desired structure.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.
    In each case, in a highly simplified, schematic representation:
    Figure 1 is a plain bearing element in the form of a plain bearing half-shell in side view.
    Fig. 2 is a schematic representation of the change in micro-slip of the overlay over its layer thickness.
    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component designations, wherein the disclosures contained in the entire description can be transferred mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.
    1 shows a multilayer plain bearing element 1 (multilayer plain bearing) in the form of a plain bearing half shell in side view. Shown is the preferred two-layer embodiment of this sliding bearing element 1, consisting of a metallic support layer 2 and a directly on the support layer 2 angeord-Neten sliding layer 3 forms. The sliding layer 3 is the layer on which slides the component to be stored.
    It should be noted that further layers can be arranged, that is, for example, a bearing metal layer 4 between the sliding layer 3 and the support layer 2, as shown in broken lines as a three-layer variant in Fig. 1, in which the bearing metal layer 4 directly on the Support layer 2 and the sliding layer 3 is applied directly to the bearing metal layer 4. Likewise, between the sliding layer 3 and the bearing metal layer 4 and / or between the supporting layer 2 and the sliding layer 3 or the bearing metal layer 4, an adhesive layer and / or a diffusion barrier layer or on the sliding layer 3, an inlet layer may be arranged. Furthermore, an antifretting layer can be arranged on the rear side of the support layer 2.
    The slide bearing element 1 can also be designed differently from FIG. 1, for example as a bearing bush. Likewise, embodiments such as thrust rings, axially running sliding shoes, or the like are possible. There are also sliding bearing elements 1 possible, which cover a deviating from 180 0 angle range. If appropriate, the supporting layer 2 can also be a connecting rod whose eye is directly coated with the sliding layer 3. In general, the sliding layer 3 can be applied directly to a component for forming the sliding bearing element 1, such as, for example, a gear for an aircraft engine. The sliding bearing element 1 is therefore not a conventional sliding bearing in the narrower sense, that is, for example, in the sense of a plain half bearing. Rather, a sliding bearing element 1 is to be understood as an element which has the sliding layer 3. In direct coatings, the element itself becomes the support layer 2.
    The support layer 2 consists of a material which gives the sliding bearing element 1 the required structural strength. In the preferred embodiment variant of the slide bearing element 1, however, it consists of a steel.
    Should a bearing metal layer 4 be arranged, different alloys known from the relevant prior art can be used for this purpose. However, the bearing metal layer 4 preferably consists of a bronze, in particular a lead bronze.
    The bearing metal layer 4 can be deposited or arranged on the support layer 2 by a conventional method known from sliding bearing technology. For example, a bimetal of the support layer 2 and the bearing metal layer 3 can be produced by rolling the bearing metal layer 3. Likewise, the bearing metal layer 4 can be poured onto the support layer 2.
    Optionally, this bimetal is reshaped and / or machined.
    If a primer layer or a diffusion barrier layer is present, this may consist of the conventional, known materials for this purpose.
    The sliding layer 3 consists of 100 wt .-% of silver or silver, optionally up to 5 wt .-%, in particular between 0.01 wt .-% to 5 wt .-%, of at least one other metal and optionally conventional impurities can have. The sliding layer 3 is thus, apart from the impurities, either of a single metal, namely pure silver or ultra-pure silver, or of a silver alloy. As a further metal is at least one metal selected from a group comprising or consisting of Cu, Sb, Mo, Co into consideration.
    Like any metal, the silver of the sliding layer 3 has a microstructure 5, which is characterized by the type of pretreatment or the deposition process. The microstructure 5 of the sliding layer 3 is shown schematically in FIG.
    In this microstructure 5, first grains 6 and second grains 7 are formed, which abut each other across the grain boundaries.
    The first grains 6 are then arranged or formed on a first surface 8 of the sliding layer 3. The second grains 7 are then arranged or formed on a second surface 9 of the sliding layer 3. The second surface 9 is that surface of the sliding layer 3, which is closer to the support layer 2. In the preferred embodiment of the sliding bearing element 1, the sliding layer 3 rests against the supporting layer 2 via the second surface 9. Thus, with the first surface 9 that surface of the two surfaces of the sliding bearing element 1, which is further away from the support layer 2. In particular, a component to be stored slides on this second surface 9. The second surface 9 is thus in a configuration of the sliding bearing element 1 as a half-shell or as a bush, the radially inner surface and the first surface 8, the radially outer surface of the sliding layer. 3
    The first grains 6 have a stem-like habit. This columnar habit can also be described as at least approximately columnar habit.
    For the purposes of the invention, a grain 6 has a stem-like habit, when a longitudinal extent 10 of the grain 6 is at least 1.5 times greater than the width of the grain 6.
    In contrast to the first grains 6, the second grains 7 have a global habitus.
    A grain 7 has a globular habit in the sense of the invention if the longitudinal extent 10 of the grain 7 is less than 1.5 times, in particular less than 1.3 times, the width extent 11 of the grain 7. a globular grain 7 can thus be at least approximately spherical.
    The sliding layer 3 has a total sliding layer thickness 12 from the first surface 8 to the second surface 9. In the preferred embodiment, the sliding layer thickness 12 is selected from a range with a lower limit of 10 μιτι, in particular 15 μιτι, and an upper limit of 100 μιτι.
    The first grains 6 are formed from the first surface 8 toward the second surface 9 of the sliding layer to a first depth 13 of the sliding layer 9, and the second grains 7 are from the second surface 9 toward the first The first depth 13 and the second depth 14 add up to the total sliding layer thickness 12. Thus, the stem-shaped habit of the first grains 6 within the sliding layer 3 changes to the globular habit of the second Grains 7.
    It should be noted at this point that although it is preferred that the first grains 6 have exclusively the stem-shaped habit and the second grains 7 exclusively the globular habit. However, embodiments of the sliding layer 3 are possible in which the first grains 6 predominantly have the stem-shaped habit and the second grains 7 predominantly have the globular habit. By the term "predominantly" is meant that a proportion of at least 80%, in particular at least 90% of the first grains 6 have the stem-shaped habit, based on the totality of the first grains 6 in the volume of the sliding layer 3, which by the first surface 8 and the first depth 13 of the overlay layer thickness 12 is defined, and a proportion of at least 80%, in particular at least 90%, of the second grains 7 have the globular habit, based on the totality of the second grains 7 in FIG Volume of the sliding layer 3 defined by the first surface 8 and the second depth 13 of the overlay layer thickness 12.
    This change can be made in the microstructure of the sliding layer 3 in which the temperature is changed during the production or deposition of the sliding layer 3. Preferably, the sliding layer 3 is produced by means of a PVD method, in particular by cathode sputtering, or deposited on the layer arranged below the sliding layer 3, in particular the supporting layer. It is further preferred if the temperature during the production or deposition of the sliding layer 3 is increased. In particular, the temperature may be increased by a value selected from a range of 10 ° C to 50 ° C.
    According to a variant embodiment of the sliding bearing element 1, it can be provided that the columnar microstructure of the sliding layer 3 extends from the first surface 8 of the sliding layer 3 to a depth 13 of the sliding layer 3 of at least 10%, in particular at least 20%, and at most 95%, in particular maximum 75%, is enough. This can be achieved via a corresponding temperature control, in particular in the specified range of the temperature change.
    It is further preferred if the first grains 6 with the longitudinal habit are oriented at least approximately perpendicularly to the first surface 8 of the sliding layer 3 with their longitudinal extension 10, as shown in the left-hand part of FIG. 2, or if longitudinal axes 15 of the first grains 6 by an angle 16 of at most 30 °, in particular a maximum of 20 °, preferably a maximum of 10 °, deviate from this vertical-right orientation. This can also be achieved by means of a corresponding temperature control, in particular in the stated range of the temperature change.
    As already stated above, stem-like first grains 6 are understood to mean grains in which the longitudinal extent 10 is at least 1.5 times the width extension 11. However, a variant of the sliding bearing element 1 in which the columnar first grains 6 have a longitudinal extension 10 which is at least twice, in particular at least three times, preferably at least four times, the width extension is preferred. This embodiment of the sliding bearing element 1 can be achieved by a corresponding temperature control, in particular in the specified range of temperature change.
    A mean diameter of the second grains 7 having the globular habit may preferably amount to a maximum of 20% of the length in the longitudinal extension 10 of the first grains 6 with the stem-like habit. This can be obtained by the appropriate choice of the temperature at the beginning of the deposition of the sliding layer. The length of the columnar grains 6 may for example be between 4 pm and 80 pm.
    It should be noted that the longitudinal extent 10 of the first grains 6 is understood to be the direction in which the respective first grain has its greatest length. Accordingly, the width extension 11 is understood to mean that direction which is perpendicular to the longitudinal extension 10. It is considered the largest dimension in this direction of each grain.
    If a relative reference to the longitudinal extension 10 of the first grains 6 has been made in the foregoing, an average longitudinal extent is referred to as an arithmetic mean of the longitudinal extent 10, i. of length, calculated from twenty single grains with stem habit.
    The mean diameter of the second grains 7 with the globular habit is understood to mean the arithmetic mean of twenty individual values of the diameter of the sphere which completely envelopes the respective grain 7 under consideration.
    The transition between the globular and the stem-shaped habit of the microstructure of the sliding layer 3 may be formed jump-shaped. Thus, the hardness of the sliding layer 3 changes abruptly from hard to the second Oberflä-9 compared to soft on the first surface 8. Preferably, however, viewed over the cross section in the direction of the sliding layer thickness 12, a hardness gradient is formed by the habitus the first grains 6 changes in a gradient-shaped manner to the habit of the second grains 7. It can be provided that the second grains 7 with the smallest diameter are deposited in the region of the second surface 7, ie at the beginning of the deposition of the sliding layer 3. By increasing the temperature during the deposition of the sliding layer 3 can be achieved that the second grains 7, which are deposited or formed on the first deposited grains 7 are deposited or formed with a larger diameter compared to it. With the progression of the deposition process of the sliding layer 3, the second grains 7 are larger in size by further increase in temperature until they change into the stem-like habit of the first grains 6. By further increase in temperature, the first grains 6 are deposited or formed with increasing lengthwise extension 10 until they reach their greatest longitudinal extent on the first surface. The result of this method is shown schematically in the right part of FIG.
    It should be noted that it occurs in the context of this method, can that, for example, among the first grains 6 with the greatest longitudinal extent also a minority first grains 6 are to be found, which have a lower longitudinal extent 10 compared to. However, this is included in the scope of this method as long as a hardness gradient, in particular with a continuously decreasing hardness, is formed over the cross section of the sliding layer thickness 12.
    For the evaluation of the plain bearing element u.a. made the following Ausführungsbei games. For this purpose, sliding layers 3 made of pure silver were deposited on support shells 2 made of steel which had been formed into shells in each case under the following conditions using DC magnetron sputtering.
    Similar results of the relation of the hardness values at the surface and the deinking zone are achieved if, instead of pure silver, a silver alloy is produced which has a proportion of at most 5% by weight of at least one of the elements Cu, Sb, Mo, Co , It is therefore not necessary to reproduce these results.
    The process gas pressure can generally be selected from a range of 0.3 Pa to 10 Pa. Optionally, it is also possible to change the habit of the grains of the sliding layer on the change in the process gas pressure during deposition, in particular together with the change in temperature.
    As process gases, at least one of the gases argon or krypton is preferably used. But it can also be used other gases, especially inert gases.
    The embodiments show or describe possible Ausführungsvarian-th of the sliding bearing element 1, wherein it should be noted at this point that also various combinations of the individual embodiments are possible with each other.
    For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the slide bearing element 1, this or its constituent parts have been shown partially unevenly and / or enlarged and / or reduced in size.
