tic增强复合材料在不同条件下的磨损行为
Keywords: 复合材料,tic金属陶瓷,磨损行为,加载率
Abstract:
？研究了tic/nicrmoalti金属陶瓷、tic/nimo金属陶瓷和钢结tic硬质合金的磨损行为,结果表明:在平稳加载条件下,金属陶瓷的耐磨性优于钢结tic硬质合金;而在冲击载荷条件下,钢结硬质合金的室温耐磨性优于金属陶瓷,但在高温下金属陶瓷的耐磨性又转为优于钢结硬质合金.与室温相比tic/nicrmoalti和tic/nimo的耐磨性分别提高31%和79%,而钢结tic硬质合金则下降52%.初步分析了不同粘结相的tic增强复合材料的磨损机制以及加载率和温度对磨损行为的影响.tic增强复合材料的磨损行为与其使役条件密切相关.
