popup.description2
It was found that the increase in the concentration of hydrogen sulfide in the chloride-acetate solution linearly accelerates the corrosion of 17Г1С-У steel at the beginning of the exposure, without changing the nature of the electrode reactions. Over time, the corrosion rate is determined by the nature of the sulfides formed on the surface, which at concentrations of 25… 100 mg / dm3 reduce it by almost an order of magnitude. At hydrogen sulfide concentrations above 500 mg / dm3, porous sulfides are formed, corrosion damage is localized, and steel absorbs almost twice as much hydrogen as at lower concentrations. This promotes the development of cracking and corrosion cracking.
