| Abstract: | A surface laser hardening test was carried out on the inserted block cam made of GCrl5 steel,which used in the LM-150 flash butt welding machine for round link chain. Its microstructure was observed,and the hardness and the service life were tested. The results show that the surface hardness of the inserted block cam can reach 67 -68HRC and its service life is enhanced more than one time after laser hardening. |
