摘要：
An influence of microalloying with surfactants such as rare earth metals (yttrium) on conducting properties of copper, produced by vacuum melting, is investigated. The physicochemical characteristics are measured on the plane specimens after high-vacuum heat treatment. The results show that the small additions of Y do not change a character of corrosion behavior of Cu but decrease the dissolution rate. Work function and stationary corrosion potential in solutions of 3% NaCl and 38% H2SO4 are increased.
