通过在铁素体和奥氏体不锈钢中添加适量Cu, 经过特殊的抗菌处理, 使不锈钢具有了优良的抗菌特性. 探索了含Cu不锈钢经过抗菌处理后抗菌析出相的分布和形貌, 抗菌检测结果表明, 含有一定量Cu的铁素体和奥氏体不锈钢显示出了很强的广谱抗菌性能.在生物电镜下观察到抗菌钢表面细菌形态的改变与组织液溢出现象.
The ferrite and austenite stainless steels containing a suitable amount of Cu may be of antibacterial ability after a special antibacterial treatment. The distribution and appearance of the precipitates appeared in the Cu--contained stainless steels were studied with TEM. The results of antibacterial examination show that Cu--contained ferrite and austenite stainless steels have broad--spectrum antibacterial properties. By using bio--TEM, a obvious change of the bacterium appearance on the surface of antibacterial stainless steel is observed and a lot of bacteria enchyma leaks out.
