It is different to detect defect in multilayer structure of an aging aircraft fuselage, 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. Corrosion often appear in multilayer structure of an aging aircraft and threaten the safety of aviation. Array pulsed eddy current imaging technique is used to detect the corrosion in multilayer structure of an aircraft fuselage. In experiment, corrosion between three and four layer of specimen can be detected effectively at the condition of increasing amplitude of exciting signal to 20 V. Compared with other methods, it can scan large areas of complex structure without the need to change the probe. Besides its application in the field of aeronautical nondestructive testing, the array PEC imaging technique can also be used in the detection of fleet, oilcan and pipeline and will play an important role in the field of nondestructive testing.
