主　　题：laser surface modification gray cast iron residual austenite martensite wear resistance 

摘      要：The distribution of residual austenite in the laser hardening laver on the gray cast iron and the change in the amount of residual austenite during sliding wearing have been investigated by X-ray *** thin foils of the hardening layer worn down have been observed by electron *** was revealed that two types of martensite are strain-induced by slid- ing wearing under load of 1.72 MPa on the hardening layer of residual *** strain induced martensite is profitable to improve the sliding wearing resistance.
