Notes:
Copper is a well-known alloying element which is used to improve the resistance togeneral corrosion of stainless steels. Our previous experiments show that the increase of coppercontent can acquire the excellent antibacterial properties and can also increase the tendency to coldformability of the ferritic stainless steels. However, the effect of alloying Cu on the resistance tolocalized corrosion has not been clarified sufficiently. In order to understand the effect of copper onpitting corrosion resistance of the ferritic antibacterial stainless steel, the electrochemicalexperiments were carried out and the anodic polarization curves were performed in 3.5% NaClsolution for two kinds of steels. The results reveal that the ε-Cu phase in ferrite matrix diminishespitting corrosion resistance of the antibacterial stainless steel in the chlorides medium. It is connectedwith the poor passive behavior of the ε-Cu phase inclusions
