Abstract
A new method has been developed for creating functional silicon carbide coatings. During high-temperature pyrolysis of hydrocarbon molecules, free carbon atoms are formed. These carbon atoms then react with molten silicon present in the subsurface layers of the substrate or with silicon vapor. The source of silicon vapor is the molten silicon in the heated zone of the reactor furnace. These coatings primarily serve to protect SiC-based ceramics, SiC-MeSi2 composite materials, carbon-carbon composites, structural graphite, as well as refractory metals and alloys from oxidation. Furthermore, SiC coatings are capable of absorbing radiation in the terahertz range and can be used in optical systems exposed to aggressive environments under external mechanical and thermal stresses.
