- •
Gradient-field pulsed eddy current probes for hidden-corrosion imaging are proposed.
- •
Analytical model of gradient field and the proposed probe is established.
- •
Signal characteristics and sensitivity to hidden corrosion of the probe are analysed.
- •
The proposed probe has higher sensitivity and accuracy in hidden-corrosion imaging.
