| Research Abstract |
In order to develop a new passivation method for removing MnS from the surface of stainless steels and forming a Cr enriched passive film on the surface, microelectrochemical electrochemical properties of MnS and chemical dissolution behaviors of MnS in chelate-containing solutions have been examined. It was found that citric acid system solutions are effective to remove MnS and to improve corrosion resistance of stainless steels.
