Abstract

The invention discloses a motor vehicle aluminum alloy wheel hub retreading repair method. The method at least comprises the following steps: 1, repairing a substrate of a wheel hub; and 2, performing original aluminum alloy wheel hub coating. According to the method disclosed by the invention, the surface hardness adhesion force and service life of the repaired aluminum alloy wheel hub can be improved and prolonged; and moreover, the surface of the repaired aluminum alloy wheel hub is new, so that the repair quality is improved, lots of resources are saved, and the environment is protected.

Description

technical field [0001] The invention relates to the field of motor vehicle repair and manufacture, in particular to a method for refurbishing and repairing an aluminum alloy wheel hub of a motor vehicle. Background technique [0002] With the development of the economy, the automobile manufacturing industry is changing day by day, and people's economic income level is increasing. Cars gradually enter the homes of ordinary people. At present, 95% of the cars on the market use aluminum alloy wheels, and aluminum alloy wheels have also become an item. The basic configuration of the car, however, when the car is in use, the aluminum alloy wheel hub is exposed outside like the car body, and surface damage often occurs, for example: after the surface layer and edges are physically damaged due to collision and corrosion, the existing motor vehicle maintenance technology cannot be effective The repair restores its state when it leaves the factory. If it is replaced with a new alum...
