Heat-Resistant Silicon Carbide Coatings on Graphite
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.
期刊介绍：
Mechanics of Solids publishes articles in the general areas of dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with analysis of contemporary technological problems.
