Corrosion Inhibition Control of Ferritic Stainless Steel in Hydrochloric Acid Electrolytes

doi:10.12068/j.issn.1005-3026.2014.11.009

Abstract

Abstract: Electrochemical method， weight loss and scanning electron microscope (SEM) were employed to investigate the corrosion behavior of ferritic stainless steel in hydrochloric acid electrolytes. SDS(sulfosalicylic acid dihydrate) and SAD (sodium doclecyl sulfate) were tested as corrosion inhibitors for ferritic stainless steel in 5% HCl at 40℃. The results showed that the ferritic stainless steel keeps active dissolving in hydrochloric acid electrolytes and suffers from uniform corrosion accompanied with intergranular corrosion along the grain boundaries. Both SDS and SAD are interface inhibitors and their inhibition efficiency have a threshold. When the concentration of inhibitor is 0. 015%， both the two inhibitors decrease dramatically the corrosion rate of stainless steel. The inhibiting efficiency of SAD is higher than that of SDS under the same concentrations.

Key words: ferritic stainless steel, hydrochloric acid, pickling, corrosion, inhibitor
