The technology of non-destructive testing of defectiveness of structural elements manufactured of metal and composite materials with a protective coating is presented. The technology is based on using the method of electron shearography in combination with thermal method of loading the object under examination. The effectiveness of the applied technology is shown in detection of damages of deposition of different types of coating on the surface of the objects under examination (of flat and complex shape) both on test specimens, as well as on full-scale structural elements (panels and turbine blades). 18 – Ref., 10 – Fig.
Key words: non-destructive quality control, diagnostics of structures, coating, electron shearography
