摘要
用环－块磨损试验机对ＴｉＣ（Ｎ）－Ａｌ２Ｏ３复合陶瓷／不锈钢摩擦副的磨损性能进行了试验研究．结果表明，分别在干摩擦和水或２０＃机械油润滑条件下，陶瓷与不锈钢的磨损质量损失都是随着载荷或速度的增加而快速增大，而且试件在水或油润滑下的磨损值反而比在干摩擦时的高．用扫描电子显微镜和Ｘ射线能谱分析发现，陶瓷与不锈钢表面之间在摩擦过程中发生了材料的相互转移与扩散，不锈钢在偶件陶瓷块的表面形成了转移膜．陶瓷／不锈钢摩擦副发生的主要是粘着磨损．
Under dry and lubricated (with water or oil) conditions at room temperature, the wear characteristics of TiC(N) Al 2O 3 composite ceramic and stainless steel rubbing pair were investigated by using a block on ring tribometer, which can well simulate the wear process of cutting tools. The test results showed that, the wear of ceramic and stainless steel increased rapidly with load and speed. Compared with dry friction condition, the existence of water or oil at contact surfaces in this test made the wear of materials more severe. A scanning electron microscope with energy dispersion X ray spectroscope was used for analysis and determination of the wear mechanisms. It has been found that the wear mechanism for metal ceramic sliding pairs is governed by the metal transfer on to the ceramic surface.
