The process of formation of protective plasma ZrB2-SiC-ALN coating on the surface of C/C-SiC composite material was studied. Coating was applied by subsonic Ar/N2-plasma jet and supersonic jet of air-gas plasmatron. The role of interphase phenomena occurring during plasma spraying in the volume of particles of ZrB2-SiC-AlN composite powder in formation of the coating layer was established. It is shown that the composition and velocity of the plasma spray jet affects the structure and phase composition of the forming ZrB2-SiC-AlN coating. Resistance of the produced coatings to thermal cyclic heating by a flame jet of oxygen-propane-butane torch was tested. Coating of 400 μm thickness showed preservation of protective properties after 15 thermal cycles. Effect of thermocyclic heating on formation of a three-zone structure in the protective coating, as a result of oxidation process was studied. Its texture and phase composition was examined by XSPA and RSMA techniques. It is found that the surface layer of the coat ing after thermocyclic heating consists of Al2SiO2-based matrix with submicron ZrO2 inclusions. 25 Ref., 3 Tabl., 9 Fig.
