中文摘要:
      采用低压等离子喷涂技术在310S不锈钢表面制备MoB/CoCr梯度涂层,然后对MoB/CoCr涂层进行激光重熔处理,对重熔后涂层的组织结构及性能进行了研究。研究结果表明,激光重熔后,涂层表面平整致密,截面的显微组织呈树枝晶—胞状晶—平面晶过渡;激光重熔过程中,微熔的310S基体元素与熔化的涂层元素发生对流扩散现象,涂层中出现Fe元素成分;激光重熔后,MoB/CoCr层的硬度明显提高。
英文摘要:
      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.
