| 发明名称 | Wheel nut and method of manufacturing wheel nut | ||
| 摘要 | 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. | ||

| 主权项 | 1. A method of manufacturing a wheel nut, comprising: annealing an aluminum (Al) alloy material; preheating the annealed Al alloy material; forging the preheated Al alloy material, to form a wheel nut; performing an anodizing treatment to form a primary coating on the wheel nut; performing a vacuum deposition to form a secondary coating on the wheel nut, which was subjected to primary coating; and performing a surface treatment using a powder paint to form a tertiary coating on the wheel nut, which was subjected to secondary coating, wherein the anodizing treatment, the vacuum deposition and the surface treatment are performed in sequence, and wherein the annealing is performed via treatment at about 380˜420° C. for about 2˜5 hr and includes furnace cooling. | ||
