摘　　要：为研究铜基石墨合金材料的摩擦性能,并预测材料的磨损量变化和寿命,研究了磨损实验数据,总结出用临界热应力状态来判定磨损量线性或非线性的增长关系的结论,并通过微观机理研究、解释并证明了结论的正确性。通过石墨润滑层损坏机理推导出磨损量计算公式并验证了公式的可行性。In order to research the friction properties of the copper-graphite alloy materials and forecast variation of attrition loss and material lifetime, test data are analyzed. It is indicate that there is a critical thermal stress status to determine the linear or nonlinear growth relationship of attrition loss and the correctness of the conclusion is explained and proved by the microscopic mechanism. Attrition loss formula is derived from graphite lubrication layer damage mechanism and the feasibility is also verified.
