磁粉探伤法在实施中的磁化控制规范

Magnetion standard of magnetic particle flaw detecting in practice

石油机械零部件表面缺陷会随着使用年限的延长而迅速延伸和扩展 ,从而导致断裂。磁粉探伤则对其表现缺陷检测具有较高的灵敏度。文中阐述了磁粉探伤基本原理 。

Surface flaw of the parts of oil equipment may expand or break out,according to its usage limit increasing in detecting sruface and near surface flaw.This paper describes the basic principle of magnetic particle flaw detection and emphatically introduces magnetion standard of magnetic particle flaw detecting method of various parts.
