摘　　要：磁粉探伤机是重要的无损检测设备,但对磁化时间的校准缺乏标准指导。本文通过计量工作中的实践研究,分别提出交直流磁化时间的校准方法,并对校准方法进行试验验证,对试验结果进行测量不确定度分析,证明校准方法的可行性。最后对校准过程中可能出现的问题及如何解决作了说明,供计量人员参考。Magnetic particle flaw detectors are important non-destructive testing equipment,but there is no standard guidance for the calibration of magnetization time.This paper proposes calibration met-hods for AC and DC magnetization time through practical research in measurement work,and perfor-ms test verification on the calibration methods.Analysis of measurement uncertainty of the test results proves the feasibility of the calibration method.Finally,the problems that may occur in the calibrati-on process and how to solve them are explained for the reference of the measurement personnel.
