RESEARCH ON EDDY CURRENT ARRAY TESTING TECHNOLOGY OF MULTI-LAYERED STRUCTURES OF ALUMINIUM ALLOY

摘要：

This paper presents an eddy current array NDT (non-destructive testing) technology that is applied to detect the corrosion damage which occurred on the second layer of hard aluminium alloy. The specimen with embedded corrosion defects in the multi-layered aircraft structure is tested. The experiment results indicated that the Eddy Current Array(ECA) have the advantages of detecting the embedded defects in the single or multiple structure, fast detection and having the ability of identifying the size and location of embedded defects, which makes the ECA have the broad using foreground in the testing of aircraft structure.
