    Abrasion-Resistant Sheathing Composition, Abrasion-Resistant Welding Wire BE2020 / 5240, and Method of Manufacture and Use thereof Technical Field The present disclosure relates to the field of abrasion-resistant materials, and in particular relates to an abrasion-resistant sheathing composition, an abrasion-resistant tail wire and a method for the manufacture thereof and an application thereof. Technical background The overall service life of a product is determined by the service life of its key components, i.e. not all parts end their service life at the end of the service life of the product, and the overall performance of the product deteriorates mainly due to causes of failure such as the wearing out of a few key components, therefore the service life becomes of the product shortened, or due to a lack of key performance values, the product is to be decommissioned.

    As a remanufacturing technology, the solder coating technology is based on the principle of soldering using the wetting and distribution of liquid solder alloy on a base metal. It is a technology for material surface processing in which a coating with special properties is formed on the surface of a base body. During the solder coating process, the base metal generally requires overall and uniform heating, and there are several heating methods such as furnace heating, induction heating and flame heating; however, the solder plating efficiency is low and special equipment is required, so the requirement for reprocessing the equipment during the service is difficult to meet. In addition, the diamond would be easily oxidized during the tailing and graphitized at high temperature, thereby causing thermal damage to the diamond, which seriously affects the abrasion resistance of the metal on the tail layer. Most welding materials have poor wettability or even no wettability to the diamond, so a mechanically encrusted structure with poor abrasion resistance is formed. Furthermore, the coefficient of linear expansion of the diamond is lower than that of most metal materials, so cracking would easily occur under the influence of the thermal stress during welding, which reduces the strength of the diamond.
    In view of this, the present disclosure is proposed. BE2020 / 5240 Subject matter of the disclosure The present disclosure is based on a first object of providing an abrasion-resistant coating composition. In the abrasion-resistant coating composition, diamond particles are used as an abrasion-resistant reinforcing material in order to be able to form an abrasion-resistant coating on the surface of a workpiece when applied to welding or solder-coating; and in the case of the abrasion-resistant coating composition, a transition metal oxide is used as a filler material, which helps to reduce the thermal damage to the diamond particles, to improve the soldering activity of diamond particles and at the same time to reduce the coefficient of linear expansion of welded goods, as a result of which cracks form on the diamond particles under the influence of the thermal stress during welding is prevented.
    The present disclosure is based on a second object to provide an abrasion-resistant welding wire containing an above-mentioned abrasion-resistant sheathing composition and a method for its production.

    Second, metals (niobium and molybdenum), which are produced by carbon as a result of the reduction of the transition metal oxides (molybdenum oxide and niobium oxide), are dissolved in items to be welded, which serves to reduce the coefficient of linear expansion of items to be welded so that it adapts better to the coefficient of linear expansion of the diamond particles , which prevents the diamond particles from cracking under the influence of thermal stress during welding.
