摘要

Currently there is an increasing interest in the application of infrared thermography on the defect detection for metal materials. As one new infrared thermography techniques, pulsed eddy current thermography is powerful to detect surface defects of metals, in which the temperature field is excited by the eddy current and the surface defects can be detected over a relatively wide area within a short time. This paper focuses on the application of pulsed eddy current thermography in multiple surface defects detection on metal. We tested two samples of ferromagnetic and non-ferromagnetic metals which have multiple surface defects simultaneously. The influences of excitation time and location of the coil on the detection results were investigated. The work shows that a metal part with multiple surface defects can be efficiently inspected using pulsed eddy current thermography with optimized setting of inspection parameters. The experimental results indicate that the optimal excitation time is of great difference for ferromagnetic and non-ferromagnetic metals with multiple defects. The results also show that the location of excitation coils influences the detection accuracy in different degrees for various defects on different metal materials.
