Our Pulsed Eddy Current (PEC) technique has been demonstrated to be capable of quantifying this defect. Based on theoretical analysis of PEC technique, the array probe is designed and the array PEC imaging technique has been supposed to detect corrosion in the multilayer structure, by selecting peak amplitude and the zero-crossing time of the time domain transient signal as the imaging features, corrosion can be imaged and detected effectively. It’s shown that the technique has the
measurement and has a lighting application foreground in the field of nondestructive testing.
Key Benefits of PECA:
– Insulation with weather jacket (aluminum, stainless steel, galvanized steel)
– Concrete/Silicate
– Composite wrap/Polymer coating
– Marine growth
