IS THERE ANY ADDED ADVANTAGE OF COMBINING TWO ORGANIC INHIBITORS WITH ALREADY HIGH INHIBITION EFFICIENCIES TO COMBAT A VERY CORROSIVE ENVIRONMENT TO A CERTAIN MATERIAL
Inhibition occurs similar to adsorption on the surface of steel or other metal. There may be competition between molecules, for example, one inhibitor with a larger hydrocarbon group will be better adsorbed, and therefore inhibit better. There may be competition for the adsorption center for better inhibition.
