IIn order to improve the corrosion resistance of 300M steel surface,NCLT was used in cw-1k solid-state Nd: YAG laser system,Hastelloy C276 coating with 800W laser power and 8 mm/s scanning speed was prepared on the surface of cw-1k solid-state Nd: YAG laser system. The macro morphology, microstructure, phase composition,microhardness,friction and wear properties and electrochemical properties of C276 coating were tested. The results show that the microhardness of C276 coating is increased by 1.4 compared with the substrate. However,the wear resistance of the coating is lower than that of the 300M steel substrate, the corrosion potential of the coating is the highest, the self - corrosion current density is the smallest. The C276 coating is prepared on the surface of 300M steel by laser cladding technology, which significantly improves the corrosion resistance of 300M steel surface, and provides a new scheme for improving the corrosion resistance and corrosion resistance of the material surface.
