Process for producing a graphite fluoride type film on the surface of an aluminum substrate
 A process for producing a novel graphite fluoride type film on the surface of an aluminum substrate in which an aluminum substrate and a carbonaceous material or polycarbon monofluoride represented by the formula (CF).sub.n are heated in an atmosphere of fluorine gas. The film has a luster, and not only exhibits high degree of hydrophobicity but also has corrosion resistance to aqueous solutions of acid and alkali as well as a mechanical strength.
