Abstract

Abstract

After remelted by laser,the pulse discharge coating was studied by TEM,XRD and hardness measurement for microstructure and microhardness.The results shiwed that the hardness of the coating was up to HV_0.11600 and even higher,which was due to the superfine structure,high density dislocations and carbonides and the coating.
