Abstrakt CZ: This work deals with qualitative phase analysis of thermally sprayed coatings created by a HVOF method. The experiment has been done on the WC-Co cermet coatings. After the deposition, the samples were thermally treated at temperatures within the range of 400 °C - 700 °C. X-ray diffraction method was used to analyze the phase transformations, which can occur during the thermal processing. Qualitative XRD analysis indicated that in course of the heat treatment, oxidation of the coating sets up already at 400 °C and expressively increased at higher temperatures.
