| Abstract: |
| MoB/CoCr gradient coatings were sprayed on 310S stainless steel using low pressure plasma spraying method, and then MoB/CoCr gradient coatings were laser remelted. The microstructure and property of MoB/CoCr coatings were studied. Results show that the surface morphology of MoB/CoCr coating is smooth and dense, cross sectional microstucture of MoB/CoCr gradient coatings consists of dentrite crystal, cystiform crystal and flat crystal from the surface to the bottom of coatings; There is convection-diffusion phenomena occurred between element of 310S stainless steel and that of coatings, Fe element appears in the coatings; Microhardness of MoB/CoCr coating increases obviously after laser remelting. |
