In article influence of nitriding on the structure and morphology of R6M5 high-speed steel by electrolytic-plasma treatment was study. It is shown that after nitriding by electrolytic-plasma treatment on the R6M5 steel surface formation of small pores, microdefects and fine inclusion. It is found experimentally that R6M5 steel surface after electrolytic-plasma nitriding at 550°C temperature formed diffusion strengthened layer with Fe4N-monophasic nitride (γ’-phase). The content of nitrogen on structural components after nitriding was determined. It is revealed that modified surface differs by having greater magnitude of the surface imperfection.
