摘要：
In article we present the results of studies of the structural state of coatings formed by the method of electrospark alloying at the discharge energy Wp = 0.13, 0.52 and 0.9 J by anodes from nickel and stainless steel X10CrNiTi18-10 on the cathode surface from X10CrNiTi18-10 steel. Anode materials, such as nickel and X10CrNiTi18-10 steel are recommended as materials, which is advisable to use for restoring the surfaces of parts from X10CrNiTi18-10 steel operating in conditions of radiation exposure. Metallographic analysis of the formed coatings showed that their microstructure consists of 3 zones: 1) 'white layer' is the layer that cannot be etched with conventional reagents, 2) transition zone or diffuse zone, 3) base metal. Using nickel and steel X10CrNiTi18-10 with increasing discharge energy, the thickness of the hardened layer, microhardness, continuity and thickness of the white layer, as well as the surface roughness are increased. Replacing the nickel anode with steel X10CrNiTi18-10 surface roughness is increased and the thickness of the hardened layer is decreased.
