Summary:The hardware-software complex which allows carrying out defect detection in materials based on various aluminum alloys was developed using a transducer based on eddy current effects. The hardware-software complex included the developed software coded in C++. A digital displacement transducer operated by an Arduino microcontroller has been designed, which can automatically move the transducer over a test object. In order to test the system operability, a series of scans of plates made of duralumin and aluminum-magnesium alloys with knowingly existing internal defects in the form of cuts imitating the presence of cracks in the metal and located at depths from 1 to 5.5 mm was made. This paper provides information illustrating the correlations between the system response to a 700 Hz signal and the presence of internal material defects. The eddy-current transducer exciting winding signal frequency exerts significant influence on this process, and this has been also demonstrated in the study.
