    In accordance with Figure 1, the present invention relates to a method of treating metallic, ceramic or stone surfaces that allows obtaining a surface with high coefficient of friction, as well as the metallic, ceramic or stone surface obtainable with said method.
    The metal surface treatment method comprises a stage of application on the surface to be treated by a laser beam (2) according to a predefined geometric pattern formed by lines to form channels (1) on the surface to be treated, where the wavelength of the laser beam (2) is within the range 532 nm to 10064 nm, the average power within the range 3 W to 100 W, and the pulse width within the range of 3 ns to 500 ns, so that the surface obtainable it comprises channels (1) with widths (a) within the range 0.01 mm to 0.1 mm, a distance (b) between channels (1) of 0.100 mm to 0.500 mm and depth (c) between 0.001 mm and 0 , 05 mm.

    The stage of application on the surface to be treated with a laser beam (2) comprises a sub-stage in which at least one of the following parameters is adjusted: average power of the laser beam (2), size of the laser beam (2) in the focus, pulse width, wavelength, type of interaction (fusion / vaporization), distance between channels (1) of the predefined geometric pattern and number of sweeps per channel. These parameters are easily controllable and tunable depending on the type of material to be treated, its effects being visible when determining the tribological parameters obtained, which are associated with the coefficient of friction.
    The method further comprises a stage of real-time monitoring of the surface texture obtainable at the stage of application on the surface to be treated by a laser beam
    (2) measured in real time where at least one of the parameters set in the adjustment sub-stage is reset.
    Below are examples of application of different types of lasers, with different powers, operating frequencies and scanning speed on the same material (AISI9840) for different focal distances, where the first two examples show the use of a laser with a length wave within the range 532 nm to 1064 nm and the third example shows the use of a fiber laser, where the wavelength is within the range 1055-1070 nm and the laser power is around 100 W. EXAMPLE 1
    A laser of Nd: YVO4 (532 nm) of 7 W of average power was used, operating at 20 kHz, with a value of M2 <1.2 and with scanning speed of 50 mm / s on the surface (material AISI9840) operating With an effective focal length of 160 mm it generates a microtexture that tested against an untreated homologous surface provides a coefficient of friction of 0.51. The value thereof after performing 4 consecutive tests is 0.51. EXAMPLE 2
    A 13 W Nd: YVO4 (1064 nm) laser of medium power was used, operating at 20 kHz, with a value of M2 <1.2 and scanning speed of 50 mm / s on the surface (material
