干摩擦和水润滑条件下等静压石墨和碳石墨摩擦学性能的对比研究
Comparative study on tribological properties of isostatic graphite and carbon graphite under dry sliding and water-lubricated conditions
摘要
Abstract
The tribological properties of isostatic graphite and carbon graphite under dry sliding and water lubricated conditions were studied.The friction test was conducted by using a pin-on-disc tribometer.The friction coefficient and the wear rate were employed to evaluate the tribological performances of the two materials,and wear morphology was used to analyze the wear mechanism.The results show that the friction coefficient of the isostatic graphite is larger than that of the carbon graphite under the dry sliding condition,and the wear rate is lower than that of the carbon graphite.Under the water lubricated condition,the friction coefficients and the wear rates of the isostatic graphite decrease obviously.The main wear form of the isostatic graphite is abrasive wear,while the main wear form of the carbon graphite is spalling wear.Finally,the tribological mechanism of the isostatic graphite under dry sliding and water lubricated conditions were systematically analyzed.关键词
