摘要

The influence of metal cations on the ability of gluconates to inhibit corrosion of mild steel in a model fresh water was investigated by electrochemical impedance spectroscopy (EIS) and immersion tests. The EIS and immersion test results showed that the corrosion inhibition of mild steel in model fresh water by gluconates was improved by metal cations that have a large value of corrosion inhibitory effect of cation, Y. The X-ray photoelectron spectroscopy (XPS) analysis showed that metal cations that have larger Y values are bonded on mild steel. It was thought that metal cations with large Y values and gluconates confer a synergistic inhibition effect on the corrosion of mild steel in model fresh water.
