METHOD OF APPLYING GAS-TIGHT COATING OF SILICON CARBIDE Russian patent published in 2016 - IPC C23C16/42 C23C16/448 

FIELD: chemistry.

SUBSTANCE: invention relates to heat-protective and anti-oxidation coatings, and can be used to increase chemical resistance and operating temperature of materials, used in aerospace industry, fuel and energy sector, etc. Method of applying a gas-tight coating of silicon carbide on high-temperature material involves placing said part in a furnace heat zone and supplying to surface of said part gaseous silicon-containing and carbon-containing components. Gaseous silicon-containing component is obtained using silicon vapour source, in form of a silicon melt, which is placed in crucible in heat zone of furnace. Carbon-containing component used is gaseous hydrocarbons.

EFFECT: reduced cost and faster process of producing coatings of gas-tight silicon carbide, higher thermal oxidative stability of protected materials, increased adhesion of silicon carbide, higher thermal oxidative strength of coated parts from various high-temperature materials.
