银或铜离子经常被选择为抗菌剂代理人。但是一些报告为抗菌剂不锈钢(SS ) 的准备涉及这二个抗菌剂代理人。AISI 420 不锈钢的抗菌剂性质和腐蚀抵抗由银植入,铜离子被调查。由于银和铜离子的合作抗菌剂效果, Ag/Cu 植入 SS 对两克否定的 Escherichia coli 的显示出的优秀抗菌剂活动(E。coli ) 并且克积极的葡萄球菌 aureus (S。aureus ) 在 2 摡慵汬? 灡牰慯档眠瑩 ? 牰 ' 覕 B 杮椠 ? 潳楬楤楦慣楴湯的全部的培植剂量?
Silver or copper ions are often chosen as antibacterial agents. But a few reports are concerned with these two antibacterial agents for preparation of antibacterial stainless steel (SS). The antibacterial properties and corrosion resistance of AISI 420 stainless steel implanted by silver and copper ions were investigated. Due to the cooperative antibacterial effect of silver and copper ions, the Ag/Cu implanted SS showed excellent antibacterial activities against both Gram-negative Escherichia coli (E. coli) and Gram-positive Staphylococcus aureus (S. aureus) at a total implantation dose of 2~ 1017 ions/cm2. Electrochemical polarization curves revealed that the corrosion resistance of Ag/Cu implanted SS was slightly enhanced as compared with that of un-implanted SS, The implanted layer was characterized by X-ray photoelec- tron spectroscopy (XPS). Core level XPS spectra indicate that the implanted silver and copper ions exist in metallic state in the implanted layer.
