    摘要： A method for forming a dense coating on a limited region of a subject body is disclosed. The method is composed of the steps of: applying one selected from the group of a compressed body of a powder of a metal and a sintered compressed body of a powder of a metal to a working electrode; executing discharge deposition to deposit a first coating from the working electrode on the subject body by applying the subject body as a workpiece of the discharge deposition; executing discharge deposition to deposit a second coating from the working electrode on the first coating by applying the subject body as a workpiece of the discharge deposition; and heating the subject body in one selected from the group of a vacuum, an air and an oxidizing atmosphere so as to densify the second coating or oxidizing the second coating at least in part to generate a solid lubricant substance.

    摘要： To form a thick coating by a discharge surface treatment, a voltage between an electrode and a workpiece during a discharge is detected, and it is determined that a discharge surface treatment state is abnormal if it is detected that the voltage is reduced. With this arrangement, it is possible to accurately detect an unstable phenomenon in the discharge surface treatment, and take appropriate measures before a state of the coating and a state of the electrode are worsened due to the unstable phenomenon. By discriminating a stability of the discharge surface treatment, the coating and the electrode are prevented from being damaged.

    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.
