METHOD FOR COLORING METALLIC MATERIAL

PURPOSE:To produce a colored metallic material excellent in design by treating a metallic material with a DC glow discharge with the material as a cathode in the atmosphere contg. hydrocarbons and kept at a specified pressure to form a carbon thin film on the surface of the material. CONSTITUTION:Th...

Zusammenfassung:	PURPOSE:To produce a colored metallic material excellent in design by treating a metallic material with a DC glow discharge with the material as a cathode in the atmosphere contg. hydrocarbons and kept at a specified pressure to form a carbon thin film on the surface of the material. CONSTITUTION:The atmosphere in a metallic vessel 10 is replaced by gaseous hydrocarbons (methane, propane, etc.), and the vessel is evacuated to a specified vacuum by a pump 12. The metallic material 14 (stainless steel, etc.) is used as a cathode and the vessel 10 as an anode, the material 14 is kept at
