【 摘 要 】

By the method of electroexplosive spraying of structurally-free copper, molybdenum and graphite are formed on the surface of the copper contacts. Microcrystalline composite coatings contain matrix of pseudoalloys Mo-Cu with synthesized electrical erosion stability carbides MoC and Mo2C. Topography, structure and phase composition of coatings are studied. It is shown that with the increase of thermomechanical effect on the irradiated surface the carbide content in the coating increases.
