| Abstract: | 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. |
