Friction and Wear Properties of Ceramic-Based Composites with a Mixture of Steel Fiber and Aluminium-Silicate Fiber
摘 要
利用热压烧结法制备了钢纤维和硅酸铝纤维混杂增强陶瓷基复合材料, 探讨了硅酸铝纤维含量对该复合材料摩擦磨损性能的影响, 借助扫描电子显微镜(SEM)观察了复合材料的磨损表面形貌, 并分析了其磨损机理。结果表明: 随硅酸铝纤维含量的增加, 复合材料的摩擦因数增大; 高温下复合材料的耐磨性能随硅酸铝纤维含量的增大而降低; 未添加硅酸铝纤维复合材料的磨损形式主要表现为脆性脱落和疲劳磨损, 并伴有磨粒磨损; 添加了硅酸铝纤维的陶瓷基摩擦材料的磨损形式均以粘着磨损为主。
Abstract
Ceramic-based composites with a mixture of steel fiber and aluminium-silicate ceramic fiber were prepared by hot-pressing sintering. The effects of aluminium-silicate fiber content on friction and wear properties of the composites were discussed, and the worn surface morphology was observed by scanning electron microscopy (SEM), and wear mechanism was analyzed. The results show that friction coefficient of the composite increased with the increase of aluminium-silicate fiber contents. While the wear resistance decreased with the increase of aluminium-silicate fiber contents at high temperature. The dominant wear mechanism of the compostire without aluminium-silicate fiber was brittle spalling and fatigue wear, and accompanying with abrasive wear, while the main wear type was adhesion wear after adding aluminium-silicate fiber.
