浸金属碳材料的载流摩擦磨损性能研究

Research on Tribology Property of Carbon Soaked by Metal with Current

以浸金属碳材料和铬青铜为配副,研究浸金属碳材料在载流条件下的摩擦磨损性能。结果表明:电流、速度、载荷是影响浸金属碳材料载流摩擦磨损性能的重要因素。在电流一定的条件下,浸金属碳材料的摩擦系数和磨损率都随速度的增大而增大;随着载荷的增大而减小。在载荷一定条件下,浸金属碳材料的摩擦系数和磨损率都随电流的增大而增大。与无电流条件下相比较,浸金属碳材料在载流条件下的摩擦系数明显减小,而磨损率却显著提高。

With the couple of carbon soaked by metal and chrome bronze, the tribology property of carbon soaked by metal with current was studied. The results showed that current, velocity and load were important factors for tribology property of carbon soaked by metal with current. Under the condition of stated current, the coefficient and wear rate increased with the increased of velocity but decreased with the increased of load. Under the condition of stated load, the friction coefficient and the wear rate increased with the increased of current. Contrast with no current, the friction coefficient of carbon soaked by metal decreased and the wear rate increased obviously.
