| Abstract: | By means of breaking tests on different Ni contents for AgNi contact materials via a CKS contact material testing machine, it was attempted to elucidate the formation mechanisms of the various surface morphology after the arc erosion process caused by break arc. The morphology of the anode and cathode surface that was eroded by a single break arc was investigated. Eight quite distinct types of the surface morphology were found by a single and repeated arcing. The formation mechanisms of the morphology types and the actions in arc erosion process were provided. |
