Abstract
Composition, structure and microhardness of steel samples after induction nitriding were studied in the work. As a result of high-temperature nitriding, saturation of R6M5 steel with nitrogen was observed as its content in the surface layer changed from 4.19 to 7.3 at.%. The maximum surface microhardness of the samples was 1950±70 HV0.98. The possibility of the formation of strengthened diffusion layers up to 200 μm deep and having microhardness up to 1500±50 HV0.98 on R6M5 steel was established. The parameters of the depth of the diffusion layer and microhardness depended on the heating temperature of the specimens and the processing duration in the course of induction nitriding.
