ResumoOwing to the toxic and carcinogenic nature of the most common corrosion inhibitor, the chromate ion, considerable effort has been directed towards developing other environmentally acceptable inhibitors. Extensive research at ARL and elsewhere has shown that the soluble rare earth metal (REM) salts are effective inhibitors of the corrosion of aluminium alloys, steel and zinc. This paper will review experimental studies in which REM salts have been used as corrosion inhibitors, and will discuss the inhibition mechanisms involved.
