Polyacrylic acid electrolyte-modified zinc phosphate conversion coatings for corrosion protection of steel
The present studies are to explore the effects of polyacrylic acid (p(AA)) polyelectrolyte macromolecules when they are internally diffused throughout the crystalline Zn)centerreverse arrowdot)Ph layer, on the improvement in corrosion protection afforded to steel by the Zn)centerreverse arrowdot)Ph, and on the degree of the alkaline dissolution of coatings. Cathodic delamination studies for polyester-modifed polyurethane (PU)-coated Zn)centerreverse arrowdot)Ph specimens were also performed to determine the role of the intermolecular chemical reaction at PU-modified Zn)centerreverse arrowdot)Ph interfaces in reducing the delamination rates of the PU topcoat from the Zn)centerreverse arrowdot)Ph. 8 refs., 2 figs., 1 tab.
