Development of New Corrosion Inhibitors and Adhesion Promoters

Abstract

It was the objective of the program to investigate the treatment of metal surfaces of aluminum, titanium and stainless steel alloys with organic polydentate agents instead of the conventional chromate-based conversion coatings in order to achieve improved paint adhesion and corrosion inhibition. Among the large number of chelating agents explored, the amino-phosphonate, amino-carboxylate and hydroxycarboxylate ligands with polymethylene backbones have shown promise. The paint adhesion characteristics of the chelate-treated metal substrates were comparable to those which had been treated with chromate- based conversion coatings (CHEMRITE).
