Parameters That Influence Corrosion Detection in Reinforced Concrete Based on Eddy Current Thermography

Figure 3

The thermograph of a sample surface with (a) and without (b) the induction coil, and the point of temperature measurement is labeled “A” in (b). (c) The surface temperature depends on the duration of the entire eddy current heating process, and the fitting line is displayed only for the heating process. (d) The surface temperature-time curves for the different corroded stages of specimen 40F12C2.
