Abstract

The synthesis and crystal properties of mixed nitrilo-tris-methylenephosphonic complexes [CuxNi(1−x){N(CH2PO3)3}]Na4 · nH2O (x = 0–1) are studied. The interaction between the obtained complexes and surfaces of steel 20 is studied via XPS. The effect of adsorbed complex layers have on the corrosion and electrochemical behavior of the steel surfaces in an aqueous medium is studied by potentiodynamically method. It is shown that the interaction between copper-nickel complexes and a steel surface is accompanied by exchange processes and results in the formation of surface layers of varying composition and anticorrosion properties.
