Magnetic Particle Testing of Compressor Rotor Vanes

摘要: 压气机转子叶片是航空发动机中的重要零部件，有铁磁性和非铁磁性两种材料。针对转子叶片的特殊形状，通过分析比较，选择磁轭法对铁磁性转子叶片进行磁粉检测。通过试验确定了合适的磁粉载液及磁悬液浓度等工艺参数，并详述了磁轭法磁粉检测的程序和要求，为解决这类零部件的检测问题提供了参考。

Abstract: Compressor rotor vanes are important components in aeroengine and their composition materials include ferromagnetic and nonferromagnetic. Aiming at the special shape of compressor rotor vanes, the method of yoke was adopted after analyzing and comparing for magnetization of ferromagnetic vanes. Proper technological parameters such as particle suspension vehicle and particle suspension concentration were acquired by experiment. The detailed test procedures and requirements were described, aiming to provide experiences for solving practical engineering needs.
