The effect of iron addition on the corrosion resistance and mechanical properties of modified aluminium bronze with chromium addition

Abstract

The effect of chromium addition both in the presence and absence of iron on the corrosion resistance of the aluminium bronze containing chromium has been further investigated. Maximum improvement in the corrosion resistance in the presence of Fe is brought about by 0.9% chromium and by 0.6% chromium is absence of Fe. Chromium addition brings about more improvements in the corrosion resistance of aluminium bronze in the absence of Fe rather than in its presence. Fe brings about an improvement in the mechanical properties. However, contents exceeding 3.8% result in deterioration of the mechanical properties. A 2% Fe both for addition with 0.9% chromium appears to be a reasonable compromise for improved corrosion resistance and mechanical properties.
