Improving hardness and wear resistance of laser hardened steel surfaces using friction treatment

摘要

The study relates to deformation hardening, resistance to softening during heating and wear resistance during abrasion and dry sliding friction of high-carbon and low-alloyed steels after laser hardening and additional surface plastic deformation with a hard-alloy indentor. It is shown that friction treatment with the sliding indentor improves significantly strength and tribological properties of laser hardened steels.
