摘要
TiN薄膜广泛应用于低速轴承、钟表齿轮等环境中,而微载、低速条件下TiN薄膜的摩擦学特性是其重要服役性能之一.采用球盘式干滑动摩擦磨损试验机,研究了多弧离子镀TiN薄膜在微载、低速条件下的摩擦磨损特性.研究表明:在本试验范围内,薄膜的摩擦系数随着载荷的增加而升高,磨盘转速和转动半径对摩擦系数基本没有影响;载荷、磨盘转速的升高缩短了材料的磨合时间,而转动半径的增加延长了磨合距离.磨损以对磨钢球的犁削磨损为主,磨损体积随转动半径的增加而增加.
Tribological behavior is one of the critical parameters of TiN films, which are widely used in lowspeed gear, horological gear and etc. In this paper, the sliding tribological properties of TiN films prepared by multi-arc ion plating were investigated by ball-on-disk tester under conditions of low speed and load. Results indicate that the friction coefficient increases with the increasing normal load, while revolution per minute （rpm） and sliding radius influence the friction coefficient slightly. The running-in time becomes shorter with the increase of rpm and normal load, but the increasing sliding radius prolongs the running-in distance. The counterpart ball exhibits plowed wear and the wear volume increases with the increasing sliding radius.
