Abstract

Structural features, electrical resistance, corrosion resistance and other properties of Cu―Cr condensates with different chromium contents were studied. The data obtained suggest that to use KM Cu―Cr as electrical contacts of arc-suppressing chambers it is necessary to use the chromium content in small quantities (up to 0,5%). Studies have shown that the additional doping with chromium makes it possible to increase the corrosion resistance by about 2 times, compared to materials that do not contain chromium, while maintaining the remaining parameters.
