Preparation method of antioxidant carbon-carbon composite material applying multiple coatings
The invention relates to the technical field of carbon composite materials, and discloses a preparation method of an anti-oxidation carbon-carbon composite material applying a multi-layer coating, and according to the preparation method of the anti-oxidation carbon-carbon composite material applying the multi-layer coating, a silicon carbide coating with oxidation resistance is formed by adopting a composite multi-coating method. More specifically, a layer of silicon carbide is coated on the surface of the carbon composite material by a chemical vapor reaction method to form the silicon carbide with a bimodal form, so that the surface roughness is improved to form a larger specific surface area. And then, carrying out secondary coating on the carbon composite material by using a chemical vapor deposition method. A compact and thick silicon carbide coating is formed on the basis of a primary coating, the oxidation resistance of the carbon/carbon composite material is improved through a multi-coating process, excellent heat resistance can be kept even in a high-temperature extreme environment of 2000 DEG C or above, and therefore the service life of the carbon/carbon composite material is prolonged.
