Abstract

The synthesis and crystal properties of mixed nitrilo-tris-methylenephosphonic complexes [Cu_xNi_(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.

铜-镍-亚硝酸-亚甲基膦酸混合配合物：合成，结构及其对碳钢腐蚀电化学行为的影响

摘要

混合次氮基-亚甲基膦酸酯配合物[Cu _x Ni _{（1- x）} {N（CH ₂ PO ₃）₃ }] Na ₄ · n H ₂ O（x= 0–1）。通过XPS研究获得的配合物与钢20的表面之间的相互作用。通过电位动力学方法研究了复合层吸附对水介质中钢表面腐蚀和电化学行为的影响。结果表明，铜-镍配合物与钢表面之间的相互作用伴随着交换过程，并导致形成了成分和防腐性能各异的表面层。
