【Abstract】 The main problem of the anti-welding characteristic of AgRENi electrical contact material was investigated on special DC condition. The influences of arc on the morphology and the constitute distribution on AgRENi contact surface were also investigated. The results showed that adding trace RE to AgNi is favorable to arc suppression as well as improvement of electrical property and contact electrical durability.更多还原
