Abstract

The temperature effect of 25, 50, 70 and 80ºC on the dissolution of copper in different concentrations of Lithium Bromide (LiBr) from 3x10-2 to 9M was investigated. Three types of corrosion have been detected: General dissolution due to the formation of soluble complex of CuBr2- between the two anodic peaks (P1 and P2) of the first and second electro-oxidation process; pitting corrosion which occurs after the formation of P2 and the second type of general corrosion form due to autocatalytic dissolution of Cu+. A new type of pitting corrosion known as metastable pitting which depends on temperature and concentration has been detected.
