摘    要:在SRV摩擦磨损试验机上进行常温干磨擦试验,比较了CoCrMoSi Al2O3ZrO2和CoCrMoSi Fe3O4两种大气等离子喷涂金属-陶瓷复合涂层以及C1Mn1Cr1碳钢涂层与35#中碳钢对磨的摩擦学特性;利用扫描电子显微镜(SEM)和扫描电声显微镜(SEAM)观察了靡损表面和亚表层的显微结构,分析了金属-陶瓷复合涂层的磨损机理。结果表明,粘着磨损占主导地位,同时存在微切削和微裂纹的扩展、连接。

关 键 词:等离子喷涂  磨损机理  金属-陶瓷复合涂层

Abstract:A series of dry friction tests of metal/ceramic composite coatings and carbon steel coating against mild carbon steel were carried out under room temperature using an SRV Friction and Wear Tester. The tribological behaviors of plasma sprayed CoCrMoSi Al2O3ZrO2, CoCrMoSi FesO4 and Cr1Mn1C1 carbon steel coatings were compared by means of SEM and Scanning Electron Acoustic Microscopy (SEAM). The results show that microcutting, the propagation and coalescence of micro-cracks of the materials appear in the wear process, adhesion wear still is the main mechnism of the metal/ceramic composite coatings.
Keywords:plasma spraying  composite coating  wear mechanism
