METHOD FOR CLOSING HOLE |
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. |
