Abstract
Abstract An industrial diamond thin film coating on an object and a method of manufacturing the same are described. A diamond film is first formed on a substrate other than the object to be coated. The diamond film is then joined to the object by means of an adhesive. Finally, the substrate may be removed from the diamond film which is already fixed to the object to provide a hard surface for the same.
