摘　　要：在CKS触头材料试验机上,对不同Ni含量的AgNi触头材料作了分断试验,试图解释在电弧侵蚀过程之后.由分断电弧引起的各种表面形貌形成的机理.首次探讨了由单次分断电弧烧蚀成的阳极和阴极表面的侵蚀形貌特征,归纳了由单次和多次电弧烧蚀引起的8种表面形貌类型,解释了这些表面形貌类型的形成机理和在电弧侵蚀过程中的作用.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.
