Abstract
Official abstract text for this publication.
Disclosed herein is a method of manufacturing a wheel nut. The method includes annealing an aluminum (Al) alloy material and preheating the annealed Al alloy material. The Al alloy material is also forged to form a wheel nut. Furthermore, the method includes performing an anodizing treatment to form a primary coating on the wheel nut and performing a vacuum deposition to form a secondary coating on the wheel nut. In addition, the method includes performing a surface treatment using powder paint to form a tertiary coating on the wheel nut.
