摘　　要：涡流检测是金属表面缺陷的一种无损检测方式,因具有高效性、安全无害的优点而被广泛应用。本文针对实际工程应用中的检测,提出一种基于涡流阻抗法的缺陷检测方法,通过COMSOL仿真,设计工件表面夹杂物的检测系统,并进行试验验证。结果表明:该方法无需与被测物体接触,能避免接触造成的磨损,具有可行性。Eddy current testing is a non-destructive testing method for metal surface defects.It is widely used because of its high efficiency,safety and harmlessness.In this paper,a defect detection method based on eddy current impedance method is proposed,and the detection system of inclusions on workpiece surface is designed by COMSOL simulation and verified by experiment.The results show that the method does not need to contact the measured object,and can avoid the wear caused by contact,and is feasible.
