The effect of CeCl3 inhibitor on the localized corrosion of stainless steel in chloride solutions
Stainless steels have been used extensively in many sectors such as medical and household appliances as well as construction. This has been primarily due to their high resistance to corrosion attacks, reasonable cost and excellent mechanical properties. However, when placed in corrosive media stainless steel is susceptible to localized corrosion attacks, especially when placed in chloride solutions. The paper explores the issue of corrosion liability of austenitic (AISI 316) and duplex (UNS S32205) stainless steels in conditions of sea water environment as well as under the influence of an inhibitor in the same environmental conditions. The behaviour of stainless steels was examined via electrochemical testing relying on DC and AC techniques, optical metallographic analysis, scanning electron microscopy and X-ray diffraction analysis. Duplex stainless steel showed better resistance to localized corrosion but a higher tendency towards general corrosion in all examined solutions. Cerium chloride in a chloride solution showed inhibiting properties for both the AISI 316 and the UNS S32205.
