NONDESTRUCTIVE TESTING OF CERAMIC COATINGS ON STEEL BY PHOTOACOUSTIC, PHOTOTHERMAL AND HIGH-FREQUENCY ULTRASOUND TECHNIQUES
Source abstract
Abstract
Abstract Adhesion of tungsten carbide coatings with a thickness of about 300 μm on steel subtrates has been tested by photoacoustic microscopy at 33.8 kHz, by photothermal radiometry at 20-200 Hz and by high-frequency ultrasound measurements at 80 MHz. Delaminated regions of the coating were detected in good agreement with the photoacoustic and the ultrasound technique.
