摘要：
The effect of passivated potential on corrosion resistance of the chromium in borate buffer solution was investigated. The electrochemical results showed that corrosion resistance of the passive film on the chromium electrode decreased with the increasing of passivated potential. The Mott-Schottky analysis showed that more acceptor concentrations in passive film due to higher passivated potential deteriorated corrosion resistance of the chromium electrode. The results from XPS showed that more chromium hydroxides were formed in higher passivated potential, while less chromium oxides were formed. More acceptor concentrations in passive films reduced corrosion resistance of the chromium electrode in borate buffer solution. Copyright (C) 2016 John Wiley & Sons, Ltd.
