表面抗菌不锈钢的研究进展

抗菌不锈钢是一种新型的抗菌材料,拥有抗菌性强、耐高温塑性好、自身无菌等良好的特性,在医疗、食品、公共卫生等领域有很好的应用前景.在实际应用中,抗菌不锈钢主要应用其表面的抗菌性能,因此,表面抗菌不锈钢较之其他产品有更高的研究价值.综述了表面抗菌不锈钢的研究进展,主要包括表面涂层型抗菌不锈钢和表面改性型抗菌不锈钢的制备工艺,以及不同类产品的抗菌能力.结果表明,目前表面抗菌不锈钢在制备及使用过程中所面临的问题主要是对生产设备和技术要求高,产品耐磨性差,当前的技术难以达到大量制备表面抗菌不锈钢的要求.结合电沉积法的特点及扩散特性,以及利用电沉积扩散法在制备抗菌不锈钢方面的应用情况,指出利用电沉积扩散法在不锈钢基体表面制备抗菌镀层将是未来制备表面抗菌不锈钢的主要发展方向.

Research Progress in Surface Antibacterial Stainless Steels

The antimicrobial stainless steel is a new type of antibacterial materials. The antimicrobial stainless steel has good antibacterial properties, good plasticity and self sterility, and withstands high temperatures. The antimicrobial stainless steel has good application prospects in medical, food, public health and other fields. Taking the practical application into consideration, the antibacterial properties of the surface of the antimicrobial stainless steel is really working. Therefore, the surface antibacterial stainless steel has higher research value than other products. This paper reviewed the research progress in surface antibacterial stainless steel, mainly including the process of surface coating and surface modification, as well as the antibacterial ability of different products, and analyzed the problems in the preparation process and application of different types of surface antibacterial stainless steel. The result showed that the main problems of surface antimicrobial stainless steel in the process of preparation and application are the high requirements of the equipment and technology and the poor wear resistance of the products, and the gap between the current research methods and the requirements of mass production of surface antibacterial stainless steel. Based on the characteristic of electrodeposition and diffusion, in combination with the applications of electrodeposition diffusion method in the preparation of antimicrobial stainless steel, it was pointed out that the preparation of antibac- terial coatings on the surface of stainless steel substrate by electrodeposition diffusion method will be the main development direction for the preparation of surface antibacterial stainless steel in the future.
