Abstract
The corrosion characteristics of SUS304 exposed to 0.5â¯M Clâ aqueous solution containing different metal cations were studied with immersion tests, surface analysis and electrochemical tests. The mechanism of corrosion with metal cations was clarified by the XPS analysis results together with the hard and soft acid and base (HSAB) concept and the passive films structure. It is supposed that metal cations with large hardness make a layer by chemical bonding with the passive films. The passive films are protected by the metal cation layer from Clâ attack, and consequently corrosion reactions are inhibited.
