摘要
In this study, the nominal 00Cr18Ni9 type alloys containing 0 to 5% Ce were melted in a inductive furnace in an atmosphere of argon, the distribution and content of cerium in these Ce-bearing stainless steels were analyzed, the composition of cerium precipitation phase was analyzed with X-ray diffraction method, the antibacterial performance of Ce-bearing stainless steels against Escherichia coli ATCC 8099 and Staphytococcus aureus ATCC 6538 were investigated with film attachment method. It is found that the stainless steels containing Ce have excellent antibacterial property, especially, not as the Cu-bearing antibacterial stainless steels, a special aging treatment is not required for Ce-bearing antibacterial stainless steels, which makes their application easy and cheap. The antibacterial mechanism of Ce-bearing stainless steels was also discussed.
