Abstract
The composition, structure and microhardness of titanium samples after induction nitriding were investigated. As a result of high-temperature nitriding, titanium was saturated with nitrogen with its content in the surface layer from 2.05 to 12.95 at.%. The maximum surface microhardness of the samples was 1400 ±50 HV0.98. The possibility of forming hardened diffusion layers on titanium with a depth of up to 100 ± 20 μm and microhardness of up to 500±50 HV0.98 was established. The parameters of the diffusion layer depth and microhardness depend on the sample temperature and the duration of treatment during induction nitriding.
