The arc erosion of CuW70/ CrCu integrated contact is first from the even volatilization of the surface Cu, following by the formation of a W shell on the surface of W skeleton, then the shell flake off, after this, new arc erosion occur.

CuW70的烧损先是表层的Cu均匀挥发，接着在骨架的表面形成一层以W为主的壳层，然后壳层剥落，裸露出来的继续烧损，如此反复，导致了触头的烧损。
