摘要
以00Cr18Ni9不锈钢成分为基础,添加0～5%的稀土元素铈（Ce）.利用电子探针分析了加铈（Ce）不锈钢中Ce的分布;用化学分析法测定了含铈不锈钢中铈（Ce）和碳（C）的含量;用X射线衍射方法测试了含铈（Ce）不锈钢中铈（Ce）的析出相成分;采用贴膜法测试了含Ce不锈钢对大肠杆菌ATCC 8099、金黄色葡萄球菌ATCC 6538的抗菌性能.结果表明： 含Ce不锈钢具有优异的抗菌性能,与含Cu抗菌不锈钢相比,含Ce不锈钢无需时效热处理就具有优异的抗菌性能.并讨论了含Ce不锈钢的抗菌机制.
In this study, the nominal 00Cr18Ni9 type alloys containing 0% to 5% Ce were mehed in an inductive furnace and protected with 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, and 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 has 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-beafing stainless steels was also discussed.
