The paper presents an experimental study of the behavior of high-density zirconium carbide in oxidizing atmosphere (in air flow). The study has been conducted with a specially developed experimental setup with a high-power technological laser providing heating of zirconium carbide in a wide range of heating rates, which make it possible to study the formation of an oxide layer at different regimes. High-speed video recording of the heated surface in the conditions of external illumination in combination with the multichannel pyrometry enabled to analyze the main features of the formation of the oxide layer at the surface of zirconium carbide. A detailed study of the zone of laser radiation exposure in an oxidizing atmosphere was performed using electron microscopy, X-ray diffraction and Raman spectroscopy.
