    摘要： The present invention provides a method for forming a coating (9, 11; 39, 41) on a limited site of a subject body (1, 21) or for producing a product repaired from a subject body. The method comprises applying one selected from the group of a compressed body of a powder of a metal, in particular a Co alloy including Cr, and a sintered compressed body of a powder of a metal, in particular a Co alloy including Cr, to a working electrode (7, 35); executing electric discharge deposition in a processing bath (5, 33) to deposit a first coating (9, 39) from the working electrode (7, 35) on the subject body (1, 21) by applying the subject body as a workpiece of the electric discharge deposition; executing electric discharge deposition in the processing bath (5, 33) to deposit a second coating (11, 41) of the metal from the working electrode (7, 35) on the first coating (9, 39) by applying the subject body (1, 21) as a workpiece of the electric discharge deposition; and heating the subject body (1, 21) in one selected from the group of an air and an oxidizing atmosphere so as to densify and oxidize the second coating (11, 41) to generate a solid lubricant substance (17, 47), suitably of Cr 2 O 3 formed by oxidizing Cr included in the second coating (11, 41).

    摘要： A method for closing a hole with a coating is provided. The method comprises attaching the subject body to an electric spark machine as a workpiece; bringing an electrode of a powder including an electrically conductive substance close to the subject body so as to lap the electrode over the hole; applying a voltage between the electrode and the subject body so as to generate electric discharge repetitiously to cause a coating closing the hole to grow from a periphery of the hole; and machining an edge of the hole before applying the voltage, or the coating along the edge of the hole during repetition of applying the voltage, to give a bevel.
