A manufacturing method for antibacterial stainless steel is disclosed, which uses the electrochemical oxidation to form an antibacterial oxidation film with a thickness of 200-500 nm on the surface of stainless steel. The antibacterial oxidation film has a strong adhesion, and its bonding strength with a base alloy is not affected by a high temperature. It is more reliable and firm than a coating type antibacterial stainless steel, with lower costs than an alloy type antibacterial stainless steel, and with simple processes and lower costs than a composite type antibacterial stainless steel.一種抗菌不銹鋼製造方法,係採用電化學氧化方法使不銹鋼材表面形成一層厚度達200-500nm的抗菌性氧化膜。該抗菌性氧化膜附著力強,不受高溫影響和基體合金的結合,比塗層型抗菌不銹鋼使用更可靠,更牢固,比合金型抗菌不銹鋼的製造成本低,比複合型抗菌不銹鋼的製作簡便加工成本低。101...調製酸性溶液102...不銹鋼材浸入103...交變電流氧化處理104...水洗105...熱水封閉處理106...乾燥處理
