本文论述了空心球形磁粉的物理性能及其使用特点。空心球形磁粉受交变磁场作用可以明显看到在工件表面上跳动,具有良好的移动性和分散性,是一种高灵敏度的磁粉。特别适用于室温和高温的干法磁粉探伤。
This article discusses the physical properties of hollow spherical magnetic powder and its use characteristics. Hollow spherical magnetic particles by the role of alternating magnetic field can be clearly seen on the workpiece surface beating, with good mobility and dispersion, is a highly sensitive magnetic powder. Particularly suitable for room temperature and high temperature dry magnetic particle inspection.
