采用机械合金化法将金属Cu,Ti掺杂到煤焦油沥青碳质中间相中,制备出掺Cu/Ti中间相碳合金。利用X射线衍射仪(XRD)分析了所制备中间相碳合金的晶体结构;通过高温端面摩擦试验研究了添加中间相碳合金润滑油的高温摩擦磨损性能;用SEM观察摩损表面的形貌,激光Raman光谱仪分析磨损表面碳的结构特征。结果表明,机械合金化掺杂金属Cu,Ti后,中间相碳合金的结晶有序度下降,向无定形结构转变;添加了中间相碳合金的润滑油,其高温减摩抗磨性得到优化,而且其减摩抗磨性能随着载荷的增大而大幅度提高;在高温摩擦机械作用下,增加载荷将促使磨损表面碳质材料的有序程度增加,其摩擦性能也越好。

The mesophase carbon alloy was prepared with incorporation of metallic elements Cu and Ti into the coal tar pitch-derived carbonaceous mesophase(CM) through mechanical alloying. The structures for the raw CM and the as-prepared carbon alloy were characterized by X-ray diffractiometer. The friction and wear behavior for the mesophase carbon alloy added into a base oil was investigated using a high temperature friction and wear tester. Results show that, the carbon alloy added with Cu/Ti shows a drop in the crystallinity, implying a transition to the amorphous. the high temperature friction abrasion resistance was optimized, which Add the middle carbon alloy of lubricating oil, In addition, as the applied load increases, the carbonaceous substances on the worn surfaces show a rise in the ordered degree. With increase load , it will be encouraged orderly degree of the carbon material on the wear surface, and its friction performance is also better ,Under the high temperature friction mechanical action.
