Ag/CuO材料因其高耐焊性和低电阻率而广泛应用于低压开关，但电弧侵蚀对其内部结构和成分的影响机制尚不清楚。本文介绍了Ag/CuO材料在不同操作次数下的电弧侵蚀行为。利用三维轮廓仪和扫描电镜对电弧蚀形貌进行表征，并利用电子探针显微分析仪分析成分和元素分布。结果表明，在接触面上观察到了一些新的、不同的电弧侵蚀形貌。电弧侵蚀区Ag基体中溶解的Cu和O含量均高于正常区。此外，阳极电弧侵蚀区Ag基体中溶解的Cu和O含量均高于阴极电弧侵蚀区。银熔池中的氧化铜颗粒在电弧侵蚀过程中发生了一系列化学反应，形成了一些新物质。
Ag/CuO materials have been widely used in low-voltage switches due to their high welding resistance and low resistivity, but the effect mechanism of arc erosion on the internal structure and composition was not clear. This paper presented arc erosion behavior of Ag/CuO materials under different operation numbers. The arc erosion morphology was characterized by a three-dimensional profilometer and SEM, and the composition and element distribution were analyzed by electron probe micro-analyzer. Results showed that some new and different arc erosion morphologies were observed on contact surface. The content of Cu and O dissolved in Ag matrix on the arc erosion zone was higher than that on the normal zone. In addition, the content of Cu and O dissolved in Ag matrix on the anodic arc erosion zone was higher than that on the cathodic. The copper oxide particles in the silver molten pool underwent a series of chemical reactions during the arc erosion and formed some new substances.
