Abstract

the influence of hydrogen sulfide concentration (0…1500 mg/dm3) in chloride-acetate solution on corrosion processes, hydrogenation and corrosion-mechanical wear of 07Cr16Ni6 steel has been studied. Hydrogen sulfide in solution, regardless of concentration, significantly reduces the corrosion resistance of steel. The wear resistance of steel in solution at hydrogen sulfide concentrations 100…500 mg/dm3 do not change significantly, and it decreases by ~30% at the concentrations 1000…1500 mg/dm3. It is associated with hydrogenation of friction surface.
