| Abstract: | In this paper,the matrix strengths and the welding strengths of different CuCr contactalloys are measured.The fracture morphologies are observed by scanning electron micro-scope. Experimental results show that the addition of carbon to CuCr alloys can improve theanti-welding property.Carbide films on the surface of Cr particles reduce the fracture stressof CuCr alloys and influence the microstructure of the welding zone,The effects of carbidefilms on the dielectrical strengths of CuCr alloys are also discussed. |
| Keywords: | vacuum interrupter contact material anti-welding property CuCr alloy |
