The Research on the Corrosion Inhibitor for the 316L Stainless Steel

Article Preview

Abstract:

In order to get an economical and high-efficiency corrosion inhibitor, in this paper the weight loss method were used to investigate the corrosion inhibition rate of the combined inhibitor. The thiourea, urotropine and Cetyltrimethyl Ammonium Bromide (CTAB) were combined each other. The results showed that double combined and triple combined inhibitor all had a high corrosion inhibition rate. Especially the thiourea combined with urotropine, whose concentration were 0.02 g/L and 0.08 g/L respectively, had a lowest cost and the corrosion inhibition rate was 91.22%.
