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.
