Current state and prospects of high-speed electron-beam evaporation and subsequent vacuum condensation of metals and nonmetals to produce electric contacts and electrodes

Abstract

The paper describes the structural features and properties of condensed composites based on copper and refractory metals (W, Mo, Cr). These condensed materials have a lamellar structure with a hierarchy of macro-, micro-, and submicron levels. In the condensed materials based on copper and chromium, supersaturated chromium solid solutions form and decompose. Examples of applying the Cu–Mo, Cu–W, Cu–Cr, and Cr–Al2O1 composites condensed from the vapor phase to produce electric contacts and electrodes are shown.
