Discussion on the Effective Value Standpoint and Peak Value Standpoint of Magnetic Particle Testing
-
摘要: 讨论了铁磁物质磁化的磁谱,得出了磁化的基本响应时间约为10-8s。因此,磁粉探伤中,磁化的效果主要取决于励磁电流(50 Hz)的峰值。Abstract: Discussion was made on magnetic frequency spectra of ferromagnetic matter magnetizing, and it concluded that basic respondent time of magnetizing was about 10-8s. Therefore magnetizing effect was dependent on exciting current(50 Hz) peak value during magnetic particle inspection.
