Mixed-surface impregnation of gear wheels made of 13Kh3N3M2VFB-Sh age-hardenable integrally alloyed steel aimed at improving surface hardness, wear-resistance, and back-to-back endurance

Abstract

An analysis has been carried out of mixed-surface impregnation of the 13Kh3N3M2VFB-Sh age-hardenable integrally alloyed steel consisting of successive vacuum carburizing, heat treatment, grinding and nitriding in the glow-discharge was made. Test results of samples hardened by mixed-surface impregnation for back-to-back endurance and wear resistance have been presented. It has been shown that mixed-surface impregnation combines the advantages of vacuum carburizing and nitriding. A surface hardness of more than 1000 HV has been achieved via the mixed-surface impregnation of this stated steel.
