ABSTRACT:
An industrial diamond coating on an object and a method of manufacturing the same are described. A diamond coating is first formed on a substrate other than the object to be coated. The diamond coating is then joined to the object by means of an adhesive. One of features of an industrial diamond coating of the present invention is heat resistance. This feature can be realized by subjecting a diamond coating to etching in order to eliminate carbon in the form other than diamond structure from the coating followed by filling void spaces occurring in the coating after the elimination with a heat resistant material. The substrate may be removed from the diamond film which is already fixed to the object to provide a hard surface for the object.
