Abstract

Rare Earth Metal (REM) containing compounds have been recently proposed as alternative inorganic "green" inhibitors to widely used inhibitor systems based on chromate and nitrite ions. New corrosion inhibitor compounds based on REM and a family of substituted cinnamates has recently been reported. These electrochemical studies showed that even low concentrations (less than 900 ppm) of cerium and lanthanum cinnamates (and their parasubstituted analogues) were able to significantly inhibit corrosion. In this paper the chemistry and morphology of the inhibited surfaces and how this relates to the corrosion inhibition mechanism will be discussed.
