Corrosion-resistant and conductive nanocarbon coating method using stainless steel as a base material, and fuel cell separator manufacturing method using the same

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for producing a nano-carbon coating layer having corrosion resistance and conductivity with respect to a stainless steel base material, and to provide the processed stainless steel base material.SOLUTION: A nano-carbon coating method includes steps for: etching an oxide film of a stainless steel base material; depositing a metal nitride buffer layer on the surface where the oxide film of the base material is etched; and depositing a conductive carbon layer so as to have nano-size thickness on the metal nitride buffer layer.
