FIELD: metallurgy.
SUBSTANCE: invention refers to fire-heat-shielding coating and can be implemented in rocket engineering at applicating coating on interior surface of nozzle of rocket engine. The installation for coating application consists of a high pressure chamber for electric-arc sputtering of graphite containing electrodes, of a shaft and of anodes secured on the shaft by means of telescopic pistons. Anodes consist of one or more sectors made out of mixture of carbon and metal-catalyst capable to encapsulation of carbon nano-particles inwards. Treated nozzle is used as cathode. Coating is made in form of nano-structural material and contains a porous frame formed with carbon nano-tubes or nano-cones, or fullerenes and atoms of metal or metals with various physic-chemical properties encapsulated in them.
EFFECT: decreased weight of coating at maintaining indicators of heat efficiency and facilitation of automation of coating application process.
