The Influence of Steel Surface Modifying with Zinc Complexes of Phosphonic Acids on the Efficiency of Its Passivation by Organic Inhibitors

The efficiency of films prepared in aqueous solutions of organic inhibitors on the surface of low-carbon steel preliminarily modified in solutions of zinc complexes with 1-hydroxyethane-1,1-diphosphonic (Zn-HEDP) or aminotrimethylenephosphonic acids (Zn-AMP) is studied by electrochemical and corrosi...

Zusammenfassung:The efficiency of films prepared in aqueous solutions of organic inhibitors on the surface of low-carbon steel preliminarily modified in solutions of zinc complexes with 1-hydroxyethane-1,1-diphosphonic (Zn-HEDP) or aminotrimethylenephosphonic acids (Zn-AMP) is studied by electrochemical and corrosion methods. It is shown that modifying considerably increases the efficiency of passivation and that Zn-AMP is much more efficient in this respect than Zn-HEDP
