The effectiveness of corrosion inhibition of mild steel and cast iron in cooling water systems by phosphonates has been studied by electrochemical techniques and weight-loss tests. The following phosphonates were investigated: aminotrimethylene phosphonate (AMP), 1-hydroxyethylene 1,1-diphosphonate (HEDP), and 2-phosphonobutane 1,2,4-tricarboxylic acid (PBTA). It was shown that corrosion inhibition of mild steel can be achieved with lower concentrations of phosphonates as compared to corrosion inhibition of cast iron. BC-80, a new inhibitor that protects mild steel, cast iron, and copper alloys in cooling water systems, was developed and tested in laboratory and field conditions.
