中文摘要：利用大气等离子喷涂和低压等离子喷涂在不同的基体温度下制备了316L不锈钢涂层,分别使用光学显微镜和显微硬度计研究涂层的组织和性能,并且对涂层进行了退火处理,研究了涂层的组织性能的变化。结果表明,对于低压等离子喷涂,通过改变基体温度,可以获得层片状组织和等轴晶组织的涂层,并且对层片状组织的涂层进行热处理,可以使其转变为等轴晶结构涂层;而对于大气等离子喷涂通过改变基体温度以及对涂层进行后续热处理,均不会形成完全的等轴晶结构涂层。在涂层硬度方面,对于原始涂层而言,等轴晶涂层的硬度低于层片状组织涂层,对于大气等离子喷涂经过热处理后的涂层硬度明显降低。

外文摘要：316L stainless steel coatings were deposited on 304 stainless steel surface by atmospheric plasma spray( APS) and low pressure plasma spray( LPPS) at different substrate temperatures. The microstructure and microhardness of the coatings were investigated by optical microscope and microhardness tests. Effect of annealing treatment on the microstructure and properties of the coatings was studied.The results show that homogeneous equiaxed coatings are observed using LPPS technology by changing substrate temperatures or after subsequent heat treatment. Atmospheric plasma spray can only prepare conventional lamellar coatings under the same condition. Hardness of the equiaxed as-sprayed LPPS coating is lower than that of the lamellar coating,and the hardness of the APS coating decreases after post-treatment.
