摘要：

The complex of physical-chemical investigations on study of regularities, mechanisms and peculiarities in the oxidation process of an alloy 06XN28MDT has been carried out. As a result of the corrosion tests the corrosion losses of Cr, Ni and Fe from surface of alloy 06XN28MDT in chloride-containing commercial waters of Karachaganak deposit with pH=6; 7 and concentration of chlorides 600 mg/l have been determined.The regularities and mechanisms of corrosion dissolution of Cr, Ni and Fe from surface of alloy 06XN28MDT depending on change of its chemical composition in the ranges of standard and components of structure have been established. It has been shown that the corrosion losses of alloy, basically, depend on its structural heterogeneity.
