Effect of O2 on the Tribocorrosion of 17Mn1Si Steel in H2S Environment

Keywords

oxygen, hydrogen sulfide, corrosion, tribocorrosion, steel

Abstract

The tribocorrosion of 17Mn1Si pipe steel in a chloride-acetate solution bubbled with H₂S, air, and their 1:1 mixture was investigated. The ingress of O₂ into an H₂S environment leads to steel destruction due to the combined effects of anodic dissolution and hydrogen-induced cracking. With O₂ presence in the solution, the abrasive nature of friction is determined by the interplay of pitting corrosion, hydrogen cracking and the formation of iron hydroxides in the corrosion products.
