１前言巴氏合金广泛应用于电机行业的轴瓦生产,通常的重力浇铸巴氏合金易出现很多缺陷,巴氏合金离心铸造能从根本上解决巴氏合金中的气孔、夹渣等缺陷,结合质量也有很大得高,因而在国内外都得到了广泛的应用。美国ＧＥ、日本ＥＢＧＲＡ等许多国外公司在订购电机时都明确提出轴 1 Introduction Babbitt is widely used in the motor industry bearing production, the usual gravity casting Babbitt prone to many defects, Babbitt alloy centrifugal casting can fundamentally solve the Babbitt hole, slag and other defects, combined with the quality It is also very large and therefore has been widely used both at home and abroad. Many foreign companies such as the United States GE and Japan EBGRA clearly put forward the axles when ordering the motors
