Abstract

A method of promotion of steel corrosion resistance by 2.6–7.4 times by steel working in a 10–30 g/l water solution of sodium nitrite after electrolytic heating-oxidation is proposed. It can be used for treatment of machine parts, tools, and production accessories and for an essential increase in their working lives without application of expensive coatings.
