Evaluation of Phosphopolyoxometalates with Mixed Addenda (Mo, W, V) as Corrosion Inhibitors for Steels

Gabriela Elena Badea,

et al.

Abstract: Nowadays, choosing a corrosion inhibitor is not only based on efficiency, but must also consider the toxicity of the compound, the impact on the environment, and, obviously, the regulations in the field. In the last two decades, a special class of substances has begun to be studied, namely polyoxometalates (POMs). Their electronic properties and redox characteristics make the polyoxometalates potential candidates to be used in many electrochemical processes, and as potential corrosion inhibitors.

“…It can be seen from the figures that the addition of the corrosion inhibitor results in a shift in both the cathodic and anodic polarization curves to the left to various extents, and the reduction in polarization current density indicates that the corrosion inhibitor has a significant inhibitory effect on both the anodic dissolution and the reduction in cathodic hydrogen ions in the corrosion process of carbon steel [ 18 ]. Additionally, the figures reveal that the corrosion potential of this inhibitor does not show significant differences at different concentrations, indicating that CV is a mixed-type corrosion inhibitor [ 30 ].…”
