摘    要:采用扫描电镜和能谱仪观察和测定了SiC/MoSi2复合材料与WC-Co对磨试样的磨损表面和磨屑的形貌及成分,研究了SiC/MoSi2复合材料与WC-Co摩擦副的干摩擦磨损性能和磨损机理。研究结果表明:SiC/MoSi2复合材料与WC-Co摩擦副的主要磨损机制在初始磨损阶段主要由微观断裂机制控制,并伴有粘着磨损、磨粒磨损和氧化磨损;在稳定磨损阶段由粘着磨损机制控制,并伴有微观断裂和氧化磨损。SiC/MoSi2复合材料与硬度较大的WC-Co磨轮对磨时的磨损率比与硬度较小的CrWMn钢磨轮对磨时的磨损率低。

关 键 词:SiC/MoSi2复合材料  干摩擦  磨损机理

Abstract:Appearance and composition of wear surface and wear debris of SiC/MoSi2 composites rabbing against WC-Co were observed and determined by means of SEM and EDS.The dry friction and wear properties and wear mechanism of SiC/MoSi2 composites rabbing against WC-Co were studied.The results of research show that the wear mechanism of SiC/MoSi2 composites rabbing against WC-Co is mainly microfracture companied with adhesive wear,abrasive wear and oxidation wear at the beginning of wear,and adhesive wear companied w...
