【 摘 要 】

Influence of hollow cathode effect (HCE) on local ion nitriding process of 16Kh3NVFMB-Sh steel was studied. Microstructures of nitrided layer, phase composition, microhardness profiles through the diffusion layer were obtained and investigated. Influence of ion nitriding duration on nitrided case depth and wear resistance was studied. Technology of ion nitriding with application to HCE for gear part was developed.
