Method for producing carbon material coated with carbon film and the use of carbon material

A method for producing a carbon material coated with carbon film comprising the steps of:

• dissolving an aromatic polyamide imide resin in an organic solvent to obtain a solution having a concentration of the aromatic polyamide imide resin of 10 to 50%, said aromatic polyamide imide resin being a resin of low molecular weight of about 10 to 100 in number of monomers;
• applying said solution to the carbon material or impregnating the carbon material with said solution, said carbon material selected from the group consisting of isotropic carbon, isotropic graphite material and material of a carbon/carbon composite;
• curing said material at 300.degree. C. to 400.degree. C.;
• and carbonizing and/or graphitizing said material by baking under a non-oxidizing atmosphere.
