he structural-phase state and wear resistance of coatings from high-chromium AISI 420 and A756 steels obtained by hypersonic metallisation (HM) were studied. It has been shown that coatings from martensitic steels after deposition contain an increased amount of metastable austenitic phase. In particular, 15 vol.% γ-faze is registered in a AISI 420 steel coating, and 70 vol.% γ-faze in a A756 steel coating. It has been established that during friction of hypersonic metallisation coatings of high-chromium steels, deformation-activated γ→α transformation in their surface layers leads to a significant increase in microhardness and the wear resistance of coatings.
