摘　　要：利用弱磁场下初始磁导率原理检测摩托车球铁凸轮轴珠光体含量是可行的。珠光体含量越高,初始磁导率越小,感应电势亦越小。该种检测方法精度高、速度快、抗干扰力强。检测后工作无剩磁及使用简便。有利于实现检测自动化,目前已应用于生产当中。It is possible to measure the perlite content in the nodular cast iron camshaft for motorcycle by applying the initial magneto conductivity principle under the weak magnetic field.The more the perlite content is,the small the initial magneto conductivity and induced electrodynamic potential.The merit of the method above mentioned is high accuracy,high speed and strong unti-interference.No residual magnetism is found after the inspection and it is convenient for use.This method is helpful to automation of inspection,which has been applied in production.
