摘要：
Eddy Current Testing (ECT) technology is suitable for the complex processing environment of Additive/Subtractive Hybrid Manufacturing (ASHM) due to its non-contact, couplant-free and high-sensitive features. An analytical model is established to calculate the internal current distribution of the semi-infinite sample without defects. A titanium alloy sample with internal artificial-defects is fabricated by ASHM and the ECT experiments are conducted on it to study the effect of the excitation frequency and the lift-off distance on the testing depth. Both the theoretical and experimental results show that for a deep internal defect, a lower excitation frequency leads to a larger reactance increment signal and the lift-off distance has little effect on the reactance increment signal. The study concludes that the optimal excitation frequency of ECT is 90 kHz, and the optimal lift-off distance is 0.97 mm. The conclusion provides a theoretical foundation for the integration of ASHM and ECT. © 2020, Press of Chinese Journal of Aeronautics. All right reserved.
