用无磁材料制作的滚动轴承是仪表及各种结构的重要部件。由于轴承常处于强腐蚀性介质中工作,因而对这类材料抗蚀性能的研究具有很大的实际意义。本文研究熔炼方法对40Co CrNiMo
Rolling bearings made of non-magnetic materials are important components of instruments and structures. Since bearings are often used in highly corrosive media, the research on the corrosion resistance of these materials is of great practical significance. This paper studies the melting method of 40Co CrNiMo
