Problems solved by technology
However, in the existing aluminum coating process, the bonding force between the aluminum coating and the magnesium substrate is low. When the external force is applied, the coating is easy to fall off from the surface of the magnesium alloy, and it is difficult to meet the requirements of the wheel.

Embodiment Construction
[0026] The specific implementation will be described in detail below in conjunction with the accompanying drawings (this embodiment is a further description of the present invention, rather than any limitation to the present invention).
[0027] Such as figure 1 Shown, the process flow chart of magnesium alloy wheel surface treatment method of the present invention. A surface treatment method for a magnesium alloy wheel includes preforming-machine adding-surface spraying aluminum-heating diffusion-final forming-heat treatment-surface coating treatment. The method of the invention can be used to make a magnesium alloy wheel with a layer of aluminum or aluminum alloy on the surface.
[0028] In the preforming process, the wheel blank is prepared by plastic deformation, and the wheel semi-finished product is obtained after machining, leaving a suitable amount of deformation for the final forming; the preforming is determined according to the specification and shape of the wheel,...

Abstract
The invention pertains to a surface treatment method of magnesium alloy wheels. The surface treatment method is characterized by the inclusion of preliminary shaping, machining, aluminium coating on the surface, heating and diffusion, final shaping, heat treatment and surface coating treatment, wherein, the preliminary shaping and the machining can provide a semi-product of a magnesium alloy wheel with a deflection left for the final shaping; after the aluminium coating on the surface and the heating and diffusion, a finished product of the magnesium alloy wheel can be obtained through the final shaping. Heating action during the procedure of the heating and diffusion and mechanical action during the procedure of deformation improve the bonding force of an aluminium coating and a magnesium alloy substrate as well as corrosion resistance of the magnesium alloy wheel, solve the problem of electrochemical corrosion of a bonding part and the problem that a coating with a common treatment method is liable to fall off, and do not reduce mechanical performance of materials of the magnesium alloy substrate with low production cost and no environmental pollution.
Description
1. Technical field [0001] The invention discloses a method for treating the surface of a magnesium alloy wheel, in particular a method for thermally deforming the surface of the magnesium alloy wheel after spraying aluminum, which is mainly used for processing and manufacturing the magnesium alloy wheel. 2. Background technology [0002] Magnesium alloy has low density, high specific strength, and good damping performance. It is known as "the green engineering material of the 21st century". With the increasing urgency of automobile lightweighting, magnesium alloys have shown great advantages in automobiles, and wheels are typical parts that use magnesium alloys as alternative new materials in the field of new-generation automobile products. However, for magnesium alloy wheels, low performance and poor corrosion resistance have always restricted its popularization and application. [0003] In terms of improving the performance of magnesium alloy wheels, Chinese patent ZL0310...
