Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The following description is only used to explain the present invention, not to limit the present invention.
[0026] The technical solution is to use a pulsed strong magnetic field to crush an oxide film in a local selective area on the surface of an aluminum alloy plate. Such as figure 1 , figure 2 , image 3 As shown, the relevant equipment may include a hydraulic press, a magnetic pulse power supply, a magnet moving device, a magnet 6, an electric heating power supply, and the like. The magnet 6 can be a solenoid coil or a uniform pressure coil, and is installed on the magnet moving device. The magnet moving device can be a two-dimensional mobile platform 3 controlled by a numerical control system. The magnet moving device is installed on the upper platform 2 of the hydraulic press, and the upper platform 2 Driven by the hydrau...
