Abstract

The types of defects and ways of their formation in the production of tiles from corundum ceramics are considered. The integrity of tiles containing artificial defects has been investigated by the method of active thermal non-destructive testing using optical heating. Single- and double-sided thermal control schemes are applied, as well as various methods of software processing of thermograms. It has been established that the best results in detecting internal defects in ceramic tiles with a thickness of 10 mm during thermal stimulation using halogen lamps are obtained by the method of unilateral thermal testing.
