| Abstract |
This article proposes and examines a method of forming heat-resistant silicon carbide coatings on graphite products. This coating forms through the simultaneous occurrence of several chemical reactions between silicon melt, carbon monoxide, and the near-surface region of graphite, at temperatures slightly above the melting point of silicon. The resulting coating is several millimeters thick and has high mechanical strength and hardness. Various methods were used to examine the samples, including Raman spectroscopy and SEM. The thermal stability of the coatings was studied by testing them in high-enthalpy subsonic air flows. The results show that the coatings can withstand exposure at temperatures up to 1750°C for 30 minutes. The self-healing mechanisms of the coating under the influence of oxygen at high temperatures were revealed. |
