Abstract

The effect of small additons of indium and thallium on the anodic behaviour of high purity aluminium (99.999%; 5N) and the anodic and corrosion behaviour of technical purity aluminium (T) was investigated with the aim of confirming the suitability of these alloys for the protection of steel constructions located in sea water. It has been found that the effects of indium and thallium additions on the anodic behaviour are less explicit in technically pure alloys. The effect of thallium on the anodic behaviour of Al-In alloy can be explained by the presence of indium atoms in this alloy and by the high mutual solid solubility of thallium in indium.

The ternary alloy A1(T)-0.1% In-0.1% Tl is uniformly dissolved in sea water and has a potential of −900 mV (SCE) in the current density region of 1–10 mA cm−2.
