Abstract
The electrochemical behaviour of pure and borated aluminium was examined. Measurements were performed in two different electrolytes at 90°C containing different trace-amounts of chloride. For borated aluminium current transients, i.e. metastable depassivation events were found. It is suggested to attribute these transients to less stable passivation layers in comparison to pure aluminium.
