摘      要：The tribological properties of isostatic graphite and carbon graphite under dry sliding and water lubricated conditions were *** friction test was conducted by using a pin-on-disc *** 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 *** 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 *** the water lubricated condition,the friction coefficients and the wear rates of the isostatic graphite decrease *** main wear form of the isostatic graphite is abrasive wear,while the main wear form of the carbon graphite is spalling ***,the tribological mechanism of the isostatic graphite under dry sliding and water lubricated conditions were systematically analyzed.
