OAR (RRY) SPECIAL TRANSLATION

Abstract

Results obtained by the 'marker' method show that the double layer of scale forms on the alloys as a result of an outward diffusion f metal and an inward diffusion of O2. The 'marker' in all instances was found at the bounda y of both layers of scale. Investigations of the chemical composition of the scale showed that the outer layer, regardless of alloy composition, consists of Cu2O, while the inner layer consists of a two-phase mixture of Cu2O and ZnO. Furthermore, it is shown that the inner layer is of unstable composition and varies with distance from the metallic core. The highest ZnO content was always found near the scale-alloy interface.
