Title:
DEVICE AND METHOD FOR PREPARING SURFACE STRENGTHENING COATING
Document Type and Number:
WIPO Patent Application WO/2019/204979
Kind Code:
A1
Abstract:
A device for preparing a surface strengthening coating, comprising a displacement platform (1), an electrode fixture (4), a sheet electrode (6), a coating (7), a workpiece fixture (10), and an electrical discharge machining power source (11). A positive electrode of the electrical discharge machining power source (11) is electrically connected to the electrode fixture (4), and a negative electrode thereof is electrically connected to the workpiece fixture (10). The coating (7) is provided on a surface of the electrode. When the electrical discharge machining power supply (11) is turned on, the displacement platform (1) drives the sheet electrode (6) held by the electrode fixture (4) to move, and the sheet electrode (6) processes a surface to be processed (9) of the workpiece (8), and forms a strengthening coating on said surface (9), so as to improve surface properties, reduce surface wear, and increase the service life thereof. Compared with conventional energy beam coating, PVD, thermal spraying, and other coating technologies; the device and method for preparing a surface strengthening coating can be adopted to carry out processing of inner surfaces of small structures, such as narrow slits and small holes, and is particularly applicable to hot extrusion dies for aluminum alloy profiles.
