Abstract
The first stage of the technique refinement for the thin hafnium carbide coatings formation on the carbon-carbon composition material (CCCM) is presented in the article, the synthesizing temperature being comparatively low to reduce the thermal stress arising in the surface. The hafnium carbide coatings formation on the CCCM surface was investigated in the HfCl4-СH4-Ar system at 1050 °C and atmospheric pressure. The rate of the chloride hafnium (IV) sublimation was studied for different gas consumption values. The hafnium carbide particle size distribution histograms were built and as a result the polydisperse particle distribution over the CCCM surface with two maximums of average diameters 5,4 micrometers and 295 nanometers were established. Ill. 9. Ref. 11. Tab. 3.
