Influence of Si and REE on the Corrosion Resistance of ZnAl40Cu3 Alloy

Abstract:

The corrosion resistance of ZnAl40Cu3 alloy are presented in the paper. Base alloy, alloy with silicon and alloy with silicon and rare earth elements were tested. The scope of the examination included: potentiodynamic and potentiostatic examinations, studies of the alloy surface condition after corrosion tests. The studies have shown, that the addition of rare earth elements improves the corrosion resistance of the ZnAl40Cu3 alloy in 3% NaCl environment. The presence of the silicon precipitates does not decrease the corrosion resistance of the ZnAl40Cu3 alloy in the 3% NaCl environment
