LASER CARBURATION HARDENING OF C_60-C_70 COATING ON 45~# STEEL
C60—C70涂层的激光增碳强化效应

The mechanism of carburation hardening of C60-C70coating on 45# steel under laser surface treatment has been studied. Rockwell hardness, metallography, SEM and XRD have been used to analyze the structure and properties of hardened layer. The results indic
