AI Technical Summary
Existing magnesium alloy wheels suffer from excessive weight, low performance, and poor stability, making it difficult to meet the demands for vehicle lightweighting and performance improvement, especially in competitive racing projects.
Magnesium alloy wheels are prepared using a specific alloy composition (Li: 6.0-12.0%, Al: 1.0-4.0%, Zn: 1.0-4.0%, total impurities ≤0.05%, balance Mg) and produced through casting, rotary forging, micro-arc oxidation and painting processes, including casting cylindrical ingots, rotary forging, micro-arc oxidation and painting.
The prepared magnesium alloy wheel hub has a density reduced to 1.5-1.6 g/cm3, and the vehicle speed is increased by 0.26%. The wheel hub did not show deformation or cracks in a million-cycle fatigue test, and has high performance stability, making it suitable for racing cars.
