Microstructure and Wear Resistance of Laser Hardening Layer on 30CrMnSiA Steel
Surface hardening of drill-stem joint material 30CrMnSiA by using 2kW power and 100mm/min scanning velocity has been performed, The microstructure and wear resistance of the transformation layer have been studied ,The experimental results show that the surface hardened layer consists of the hardened region and the interim region and the temper microstructure,The microstructure of hardened layer was very tiny,Its wear resistance higher than the 30CrMnSiA steel in the normal state
