干摩擦及水或油润滑下TiC（N）—Al2O3陶瓷／不锈钢摩擦副的磨损性能研究

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２性能进行了试验研究。结果表明，分别在摩擦和水或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速度的增加而快速 增大，而且试件在水或油润滑下的磨损２值反而比在干摩擦同。

Wear Properties of TiC(N) Al 2O 3 Composite Ceramic Stainless Steel Pair under Dry and Lubricated Conditions

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.
