On breaking capacity of the CuCr25 composite material produced with electron-beam cladding

The copper chromium composite coatings produced by the electron beam cladding in the vacuum on the copper substrate and electrical contacts CuCr25 produced by solid-phase sintering in a hydrogen atmosphere have been investigated. The copper chromium composite coatings produced by the electron beam cladding showed higher values of breaking capacity compared with the sintered contact material.
