Potentiostatic oxidation of AgCu50 alloy in alkaline solution in the presence of chlorides
Source abstract
Abstract
SEM and EDS analyses of AgCu50 alloy were performed after potentiostatic oxidation in an alkaline solution in the presence or absence of chloride ions. Oxidation in pure alkaline solution was favoured on the portion where a eutectic mixture was present on the surface. There was an essential difference between SEM images obtained in pure alkaline solution and in the presence of chloride, when voluminous deposits covering the whole eutectic area and expanding towards the middle of primary crystals appeared. EDS analysis confirmed that both oxides and chlorides of silver form in parallel. Chlorides disturb the protective performance of copper oxides.
