In order to improve the surface hardness and toughness of dies,several typical die materials,such as 7CrSiMnMoV,Cr12MoV,CrMo cast iron,were hardened with a high power diode laser and the optimal laser parameters were obtained.Results show that the optimal laser parameters can meet the requirement of the hardness of dies and provide a guarantee to the hardness and toughness of dies in future application.
