Abstract

Abstract

Based on the corrosion issue of cooling water system in Tianwan nuclear power plant,the corrosion electrochemistry of inhibition on copper and stainless steel was studied using electrochemical method.Results show that inhibitor have excellent corrosion inhibition efficiency on copper in low chloride concentration solution and simulated solution.The optimum inhibitor is the compound consisting of TTA and sodium orthophosphate.At the same time,the inhibitor elevated the breakdown potential of stainless steel and contributed to the enhancement of corrosion resistance.
