Abstract: A method for forming oxidation resistant multi-coating on carbon material is provided to manufacture the multi-coating having superior airtight property by coating a surface after a CVR process with carbosilane polymer. A method for forming anti-oxidative multi-coating on carbon material comprises a step of allowing carbon material to react with silicon gas or silicon oxidation gas, which is provided by pack power containing carbide, to deposit a first coating layer containing SiC on the surface of the carbon material. The carbon material having the first coating layer is coated with polycarbosilane solution to form a second coating layer. The carbon material is subject to a heat treatment process in order to form carbide by thermally decomposing the second coating layer. The polycarbosilane comprises at least one selected from the group consisting of polymethylcarbosilane, polymethylphenylcarbosilane, polyvinylcarbosilane and polymethylsilane.
