Ti（CN）－Al_2O_3复合陶瓷与金属摩擦副的摩擦学特性研究

Tribological Characteristics of Ti(CN)-Al_2O_3 Composite Ceramic and Metal Pairs Lubricated with Water and Oil

本文对水及油润滑条件下Ｔｉ（ＣＮ）－Ａｌ２Ｏ３复合陶瓷与纯铝、纯铁及不锈钢三种金属的摩擦、磨损特性进行了研究．在两种条件下，随着载荷及速度的增加，三种摩擦副的磨损量均明显增大．但两种润滑条件下的变化趋势稍有差别，水润滑时摩擦副的磨损量比油润滑时的大．与干摩擦时的试验结果相比，水或油的存在不仅没起到减磨作用，反而使磨损加剧．能谱分析结果表明，两种润滑情况下，金属与陶瓷间均有材料的转移或扩散发生，但水润滑时摩擦副材料间相互转移的量比油润滑时更大．

The tribological characteristies of Ti(CN)-Al2O3 composite ceramic sliding against three metals:aluminium, iron and stainless steel under lubrication, were investigated by using a block-on-ring tester.The wear quantities of the three rubbing pairs under lubrication of either water or oil increased obviously with load and speed, more rapidly when lubricatcd with water. Compared with the results of dry frictiontest, the lubrication with water or oil resulted in higher wear of the materials under the selected testing conditions. The X-ray energy dispersion analysis showed that the metal transfer on to ceramic surfaceoccurred in the sliding process under both lubrication conditions, but the transfer amount of metals for lubrication with water was greater than that with oil.
