摘要

Nanostructured heat-resistant tantalum carbide coatings on a carbon composite material were synthesized and characterized in this work. The main goal of tantalum carbide deposition is to decrease diffusion of oxygen to the composite support during operation at high temperatures of up to 1600°C and to protect the carbon surface against oxidation. A tantalum carbide coating was obtained by tantalum chloride deposition from the gas phase in methane atmosphere. Characterization of coatings was performed by scanning electron microscopy, x-ray diffraction, and energy dispersive x-ray spectroscopy techniques. It was established that the reaction of TaC synthesis proceeds to the highest extent at 1000℃ with the coating thickness of 20 μm and tantalum interpenetration depth into the carbon composite structure of 400 μm. The obtained data on the composition and structure of coatings showed that the nanostructured coating material interacted strongly with the surface of carbon composite. The obtained coating had low porosity and could be effectively used for protection of a carbon composite in oxidative environment at high temperatures.
