摘要(Abstract)：

采用放电等离子烧结方法制备Cu-10Cr电接触材料,利用JF04C触点材料测试系统对Cu-10Cr电接触材料进行恒流条件下的电接触燃弧试验。分析在直流阻性负载条件下Cu-10Cr电接触材料的转移损耗情况,观察其燃弧侵蚀微观形貌,探讨材料的燃弧机制。结果表明:直流电弧会引起材料表面的熔化和转移,电流高于35 A时触点材料发生从阴极向阳极的转移;电接触表面呈现有熔池、浆糊状、气孔、裂缝、菜花状等多种微观形貌特征;燃弧能量随燃弧时间的增加而增大,并且在该试验条件下燃弧能量E和燃弧时间t存在线性关系。

关键词(KeyWords)： Cu-10Cr电接触材料;电弧侵蚀;微观形貌;燃弧能量;燃弧时间
