摘　　要：试验钢进行了固溶及时效的抗菌处理,分析和研究了处理后含铜铁素体不锈钢组织和性能。采用不锈钢电解抛光技术与背散射电子的晶体取向衬度成像原理相结合,利用扫描电子显微镜(SEM)、透射电子显微镜(TEM)及能谱仪(EDS)对析出相形状、大小、分布及其成分进行了研究,测定和对比了试验钢抗菌处理前后的力学性能、杯突值和硬度值。研究结果表明:抗菌处理后试验钢具有优良的抗菌性能和深冲性,为该种材料用于抗菌制品工业化生产提供了依据。In order to clarify and predominate the effects of antibacterial treatment on the microstructure and characteristic of copper-bearing ferrite stainless steel, the solution treatment and aging treatment were carried out. Combining the unique electrolyte polishing technique for stainless steel with the imaging principle of back scattering electro-crystal tropism, SEM, TEM and EDS equipment were employed to analyze the shapes, sizes, distribution and composition of the precipitation phases. The mechanical properties, cupping values and hardness of tested materials before and after antibacterial treatment were measured and analysed. The result reveals that the as-treated steel possessed antibacterial property and excellent drawing working ability. The study is helpful to practical application of this kind of antibacterial material.
