Вплив термообробки і складу штучної морської води на локальну корозію труб зі сталі 08Х18Н10Т

Abstract

The effect of heat treatment and the composition of artificial sea water on local and local corrosion of steel is investigated. It is shown that heat treatment ambiguously affects the structure of alloy steel. Investigations of thin sections made it possible to establish the presence of groove, twin, and stepped metal structures in the samples. It was established that the introduction of sodium hydroxide into artificial seawater causes a decrease in the tendency of steel to local and local corrosion. The introduction of 10 g∙L–1 NaOH in the composition of water causes the disappearance of pitting corrosion.
