Abstract
The work purpose consists in the investigation of carbometal coatings wear-resistance and microhardness depending on chemical structure of their components. The investigation object is carbide-metal coatings. The result analysis of comparative wearresistance tests witnesses that with micro-hardness increase in metal carbides of compositions: Cr3C2, WC, TiC, TiCN, at a constant content of cladding metal (30...35mass %), a value of wear decreases according to the linear law. Wear intensity of coatings of clad carbide mixtures with different materials is defined to a certain extent with wear intensity of material added to the matrix. In the course of the work there were developed coating compositions reinforced with quasi-crystals, there is defined an optimum composition and modes of coating application with the gas-detonation method and their wear-resistance and micro-hardness were investigated.
