磁力探伤缺陷显示膜

DEFECT INDICATION FILM USED IN MAGNETIC NONDESTRUCTIVE TESTING

缺陷显示膜是一种新的磁力探伤显示材料,可以代替现有的磁粉和磁悬液,灵敏度高于干磁粉,接近磁悬液,A型试块可清晰显示。

Defect indication film, as the replacement of present magnetic particle and magnetic liquid, is a new method of nondestructive testing for ferromagnetic material work-piece. Its sensitivity is higher than magnetic particle, and is close to magnetic liquid, 'A' testing block can be indicated clearly.
