I. Introduction
With the rapid development of the automotive industry, as an important part of a vehicle, the appearance and performance of a car wheel hub directly affect the overall image and driving safety of the vehicle. Due to various reasons, wheel hubs may suffer damages such as scratches, deformations, and corrosion, which require repair. This paper aims to explore the wheel hub repair process and provide scientific and standardized methods for wheel hub repair.
II. Wheel Hub Damage Assessment
(A) Visual inspection
Conduct a comprehensive visual inspection of the wheel hub to observe whether there are damages such as scratches, abrasions, deformations, and corrosion. Record the location, degree, and type of damage to provide a basis for subsequent repair work.

(B) Dimension measurement
Use measuring tools to measure the diameter, width, PCD (pitch circle diameter of bolt holes) and other dimensions of the wheel hub to check for deformations. If the dimensional deviation is large, correction or replacement of the wheel hub may be required.

(C) Dynamic balance detection
Install the wheel hub on a dynamic balancer for detection to determine whether there is an imbalance phenomenon. If the dynamic balance is poor, it will affect the driving stability and comfort of the vehicle and needs to be adjusted.

III. Surface Treatment
(A) Cleaning
Use cleaning agents and high-pressure water guns to clean the wheel hub to remove surface dirt, oil stains, and dust. For severely contaminated wheel hubs, degreasing agents can be used for soaking and cleaning.

(B) Sanding
Use sandpaper or grinding wheels to sand the scratched, corroded and other damaged parts on the wheel hub surface to remove the oxide layer and damaged metal layer and make the surface flat and smooth. Pay attention to the force and direction during sanding to avoid excessive sanding that causes the wheel hub to become thinner.

(C) Sandblasting
For wheel hubs with severe surface corrosion or requiring large-area repair, sandblasting treatment can be adopted. Sandblasting can remove rust and old paint layers on the wheel hub surface, increase surface roughness, and improve the adhesion of subsequent painting.

IV. Selection of Repair Methods
(A) Scratch repair
For minor scratches, sanding can be done first and then polishing. If the scratch is deep, a filler can be used for filling, then sanded flat, and finally painted.

(B) Deformation repair
If the wheel hub is deformed, professional wheel hub correction equipment can be used for correction. When correcting, appropriate correction methods and forces should be selected according to the material and deformation degree of the wheel hub to avoid damaging the wheel hub.

(C) Corrosion repair
For corroded wheel hubs, sanding treatment can be done first to remove the corrosion layer, and then anti-rust agents can be used for treatment to prevent further corrosion. If the corrosion is severe, welding repair or replacement of the wheel hub may be required.

V. Painting
(A) Primer spraying
Spray primer on the repaired wheel hub surface. Primer can play a role in rust prevention and increasing adhesion. Primer should be sprayed evenly with moderate thickness to avoid phenomena such as sagging and missed spraying.

(B) Color paint spraying
Select appropriate color paint according to customer requirements for spraying. The color paint should be the same as the original car color. Pay attention to the distance, angle, and pressure of the spray gun during spraying to ensure that the color paint is uniform and smooth.

(C) Clear coat spraying
Spray clear coat on the surface of the color paint. Clear coat can increase the gloss and wear resistance of the wheel hub. Clear coat should be sprayed evenly with moderate thickness to avoid phenomena such as blistering and orange peel.

VI. Quality Inspection
(A) Visual inspection
Check whether the surface of the wheel hub is flat and smooth, whether the color is uniform, and whether there are defects such as sagging, missed spraying, blistering, and orange peel.
