摘　　要： 采用电弧喷涂优化工艺制备316L不锈钢涂层,利用扫描电镜、能谱仪和X射线衍射仪等对涂层的组织及物相进行分析,同时对涂层的硬度、结合强度进行了测定。结果表明,涂层具有典型的层状形貌,涂层截面较为致密,局部区域出现粗大孔洞;涂层与基体之间主要为机械结合,结合强度较高;涂层硬度的最大值出现在涂层中部,靠近界面的基体组织发生加工硬化。 316L stainless steel coating was prepared by arc spraying through optimization process.The microstructure and phase of the coating were studied by SEM, EDS and XRD.The coating's hardness and binding strength were also tested.The results show that the coating has typical lamellar structure, the cross section of the coating is dense and there appears local coarse holes.The coating and the substrate appears mechanical bonding;the maximum hardness of the coating is presented in the middle of the coating layer and work hardening appears at the matrix near the interface.
