Composite materials (CMs) based on copper, refractory and rare-earth metals and carbon are widely used as electrocontact materials for contact parts of medium-and high-current switchgears.In addition to the conventional powder metallurgy processes for producing these materials, they are also obtained by high-rate electron-beam evaporation-condensation of composite components from separate water-cooled crucibles with a subsequent layer-by-layer condensation of the tempered vapor flows on a rotating steel substrate.
