Surface Treatment Technology of Automobile Wheel Hub

In the 20th century, with the development of society, people's demand for cars is increasing.hubIt is an important part of the car, and the performance of the wheel hub is directly related to the performance of the whole vehicle.

The surface treatment method of the magnesium alloy grinding wheel includes grinding the surface of the magnesium alloy grinding wheel workpiece to remove oil stains, ultrasonic cleaning after anodic electrophoresis; then performing micro-arc oxidation treatment, then spraying, cleaning, drying, and then nickel plating, washing, and drying; and then performing Cathodic electrophoresis, water washing, curing; and then the intermediate coating is dried by acrylic resin, and the top coat is sprayed and cured.

This method firstly performs electrophoresis treatment on the workpiece, forms a layer of electrophoretic paint film on the surface of the workpiece, forms a uniform, smooth and strong adhesion paint film on all parts of the hub, and then forms a layer of nickel-plated micro-arc oxidation layer on the surface of the paint film , cured by cathodic electrophoresis, intermediate paint and spray topcoat.

theAluminum alloy wheelsThe surface is mechanically polished, the surface is alkaline etched, and the surface of the aluminum alloy wheel hub is roughly polished with an electrolyte with a high acid concentration; the aluminum alloy wheel is finely polished with an electrolyte with a low acid concentration.
