Impact of plasma hardening on the wear resistance of 38XC steel

Resumo

The impact of plasma hardening on the wear resistance of 38XC steel was studied. It has been found that the wear resistance increases by 53.7 times under the condition of dry friction compared to the normalized state and by 12.7 times compared to the improved state. During plasma hardening, the wear of 38XC steel under dry friction is equal to the normalized steel 15 with lubrication; and the wear is not increased in case of a 1.5-fold increase in the load. The addition of HADO revitalizant to oil contributed to an approximately twofold decrease in the wear of 38XC steel with plasma hardening during wearing-in after cutting off the lubricant.
