Abstract
Uniform and strong carbon film can be formed on a surface of a metal substrate or metallized substrate without damaging optical, thermal and electrical characteristics which are original to carbon surface by electrodepositing the carbon film on the substrate from electrodepositing liquid containing carbon and water soluble electrodepositing resin and then heat treating the carbon film to decompose and release said resin.
Claims15
A method for coating a surface of a metal or a metallized body to form a substantially pure carbon coating thereon comprising treating said surface with an aqueous electrodepositing liquid consisting essentially of carbon and at least one water soluble organic resin to form an electrodeposited carbon film on said surface and heat treating said carbon film at a temperature of about 300.degree. to 1,000.degree. C. to substantially completely decompose the organic resin in said carbon film.
