A Multi-Metal Corrosion Inhibitor for Potassium Formate Solutions

Abstract:

A multi-metal corrosion inhibitor was tested in potassium formate solutions by electrochemical and immersion testing methods. The results showed that the inhibitor could provide full protection on mild steel, aluminum, copper and brass, and good protection on soft solder. For cast iron, a secondary inhibitor would be needed to provide protection of pitting and crevice corrosion.
