Abstract
Electric-discharge coatings on the samples made of steel 30ХГСА fabricated using a UR-121 installation are investigated. Electrodes for electric-discharge machining are fabricated by hot compacting from the powders prepared by electroerosive dispersing of waste of high-speed steel Р6М5. The microstructure, thickness of the coating layer, and its surface state are studied using modern investigation techniques. Roughness parameters of wares and microhardness of the electric-discharge coating and substrate made of steel 30KhGSA are determined. It is established that the coating microhardness is larger than that one of the substrate by a factor of 2,1, which can be associated with a nonuniform distribution of the particles of high-speed steel in the electric-discharge coating. It is shown that powder materials fabricated by electroerosion dispersing from high-speed steel wastes can be used as the electrode material to fabricate various functional coatings by electric-discharge alloying.
