在漏磁法检测中为保证检测灵敏度,要求使被测材料磁化到饱和状态,降低可检测出的最小缺陷值.本文对铁磁性材料的开路磁化与闭路磁化进行比较,阐述了材料的磁化曲线的是在闭合磁路磁化条件下测得的,开路磁化曲线与材料的形状和尺寸有关,并且在开路磁化基础上论述了漏磁检测磁化方式的选择方式.

To improve inspection sensitivity, the measured material comes to saturation magnetization is required. It can reduce value of the smallest flaws which the inspection system discover. The comparison of ferromagnetism material magetization configration is done between broken way and circle in the paper. That the material''s magnetizaton curve is measured under in circle way is brought forward. The broken way of magnetization curve is also related with shape and size. And on the basis of the broken way of magnetization discusses magnetization of the magneticflux leakage testing method.
