中文摘要：采用整体熔炼法在1Cr13低碳马氏体不锈钢中添加3%Cu和1%Mo制备试样，试样经锻后退火及不同的热处理后，测试其抗菌性、硬度，并进行显微组织观察。结果表明：铜和钼的加入能显著提高不锈钢的硬度；1Cr13Cu3Mo的硬度随淬火温度升高先增大后减小；回火后，随回火温度的升高，硬度和抗菌率均呈先增大后减小的趋势；1Cr13Cu3Mo经1100 ℃× 20 min，淬火 + 450 ℃× 2 h，回火后，综合性能最好。
英文摘要：The low carbon martensitic stainless steel samples containing 3%Cu and 1%Mo were prepared through integer melting. The samples were annealed after forging and then heat treated at different temperature and time. The antibacterial property, hardness was measured and the microstructure was observed. The results show that adding Cu and Mo into stainless steel can increase the hardness obviously; the hardness first increases then decreases with the increase of quenching temperature. After tempering, the hardness and antibacterial property first increase then decrease with the increase of tempering temperature. The best heat treatment process of 1Cr13Cu3Mo is: quenching at 1100 ℃ for 20 min, and tempering at 450 ℃for 2 h.
