Abstract
⺠Selective CO2 laser surface melting and alloying technologies were adopted. ⺠Thermal fatigue resistance of H13 steel is improved. ⺠Thermal fatigue resistance would be enhanced remarkably by laser alloying with 75%Cr25%Ni mixed powder. ⺠Laser alloyed zone has excellent properties such as resisting crack initiation and oxidation corrosion. ⺠Cracks and oxidation corrosions are restricted within narrow limits structured by laser scanning tracks.
