| Abstract: | The laser transformation hardening(LTH) technology which could improve die life was put forward in accordance with the wear which formed the die failure mainly. The structure, wear resistance and wear mechanism of hardened layers in CrWMn steel by laser transformation were researched. The results were as follows: the wear resistance of hardened layers by laser transformation were improved more remarkably than those of common quenching; in the condition of quenching and LTH, hardening effect and wear resistance were optimum. |
