| Abstract | Tensile fracture at room temperature and the faying microstructures of vacuum casting Cu-30CrTe, Cu-30Cr and sintered CuCr25 contact materials after diffusion welding in vacuum were evaluated by Optical Microscope and SEM. It is shown that there are different fracture characteristics in the three contact materials, and distinct microstructures formed at the faying surface of the Cu-30CrTe from that of the Cu-30Cr and sintered CuCr25. Consulting the XPS surface analysis results of elemental distribution and valence state of trace Te in the Cu-30CrTe contact material, the mechanism and principles of trace Te improving anti-welding property of Cu-30CrTe contact material are discussed. ? 2012 IEEE. |
