磁場指示器
Magnetic field indicator
磁粉探傷將鋼鐵等磁性材料制作的工件予以磁化,利用其缺陷部位能吸附磁粉的特征,依磁粉分布顯示被探測物件表面缺陷和近表面缺陷的探傷方法。 該探傷方法的特點是簡便、顯示直觀。
Magnetic particle inspection magnetizes workpieces made of magnetic materials such as steel and the like, utilizes the characteristic that the defective parts can absorb magnetic particles, and displays surface defects and near-surface defects of the detected objects according to the distribution of the magnetic particles. The flaw detection method is characterized by simplicity and intuitive display.
磁粉探傷與利用霍耳元件、磁敏半導體元件的探傷法,利用磁帶的錄磁探傷法,利用線圈感應電動勢探傷法同屬磁力探傷方法。
Magnetic particle inspection is the same as magnetic inspection using Hall element, magnetic sensitive semiconductor element, magnetic tape recording and coil induced electromotive force.
