Abstract
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
