| 摘 要： | 利用ANSYS有限元分析软件对5种Al2O3基陶瓷材料(纯Al2O3、Al2O3/TiC、Al2O3/(W,Ti)C、Al2O3/Ti(C,N)和Al2O3/SiCw)在MRH-3环块磨损试验机上与硬质合金摩擦进行模拟仿真,得到摩擦磨损过程中的应力及分布,并与室温下的磨损实验结果相比较,同时还探讨了不同添加剂的Al2O3基陶瓷的磨损机理.结果表明:不同成分的Al2O3基陶瓷材料在摩擦磨损过程中最大主应力位于摩擦副接触区中心,最大剪应力位于摩擦副接触区边缘;载荷对主应力和剪应力大小的影响比转速的影响大;在相同的摩擦条件下,受到合应力越大的陶瓷其磨损率越大;合应力越大的陶瓷磨损后陶瓷表面越容易产生微裂纹.5种Al2O3基陶瓷磨损率的大小为:Al2O3Al2O3/(W,Ti)CAl2O3/Ti(C,N)Al2O3/TiCAl2O3/SiCw.
