Investigation of the composition, structure and hardness of tool steel after induction nitriding
The composition, structure and microhardness of steel samples after induction nitriding were studied. As a result of high-temperature nitriding, the saturation of P6M5 steel with nitrogen with its content in the surface layer from 4.19 to 7.3 at.% was observed. The maximum surface microhardness of the samples was 1950±70 HV (200gf). The possibility of forming hardened diffusion layers with a depth of up to 200 μm and a microhardness of up to 1500±50 HV (100gf) on P6M5 steel was established. The parameters of the diffusion layer depth and microhardness depend on the sample temperature and the duration of treatment during induction nitriding.
