Carbon film coating structure for work and carbon film coating method for work

Abstract

A carbon film coating structure and a method for coating that structure onto a work are provided, in which a carbon material such as a carbon nanotube is applied to a work for coating thereof with high density and high integration so that the coating has an outstanding electrical conductivity and thermal conductivity, heat resistance, high strength and flexibility owing to the characteristics of carbon, and in which a carbon such as CNT is applied to the work for coating thereof easily and inexpensively, and with high density and high integration. A carbon material is coated or impregnated on a surface layer of a work. The work can deposit a suboxide or oxide containing metal ions. A porous primary film is formed on the surface layer of the work. The carbon film is coated or impregnated on an irregular part of the surface layer of the primary film.
