Motorcycle aluminum alloy forging is an important part of motorcycle structure, its surface treatment and anti-corrosion properties have an important impact on the life and safety of the motorcycle. This paper discusses the surface treatment methods and anti-corrosion properties of motorcycle aluminum alloy forgings.
- Surface treatment of aluminum alloy forgings
The surface treatment of aluminum alloy forgings mainly has the following methods:
Anodizing treatment: Through electrolysis, a dense oxide film is formed on the surface of the aluminum alloy to improve corrosion resistance and wear resistance. This treatment method works well, but the cost is relatively high.
Sandblasting treatment: The use of high-speed spray sand to clean the impurities and oxide layer on the surface of aluminum alloy, increase the surface roughness, and improve the adhesion of the coating.
Chemical conversion film treatment: forming a protective film on the surface of aluminum alloy through chemical reaction, commonly used chromate treatment and phosphate treatment. This method has low cost, but the film layer is thin and the corrosion resistance is relatively poor.
- Corrosion resistance
The corrosion resistance of aluminum alloy forgings is mainly affected by the following factors:
Alloy composition: Different components of aluminum alloys have different corrosion resistance. Through reasonable alloy design, the corrosion resistance of aluminum alloy itself can be improved.
Surface treatment quality: High quality surface treatment can significantly improve the corrosion resistance of aluminum alloy. For example, the oxide film formed by anodizing treatment can effectively isolate air and water and reduce the corrosion rate.
Environmental conditions: During the use of motorcycles, they will face different environmental conditions, such as humidity, temperature, salt spray, etc. These factors will affect the corrosion resistance of aluminum alloy forgings. In harsh environments, the corrosion rate of aluminum alloy forgings will be accelerated.
In order to improve the anti-corrosion performance of motorcycle aluminum alloy forgings, the following measures can be taken:
Select the right aluminum alloy composition to meet the corrosion resistance requirements under specific environmental conditions.
Strictly control the surface treatment process, ensure the treatment quality, improve the adhesion and corrosion resistance of the coating.
For the harsh use environment, additional protective measures can be taken, such as adding corrosion resistance agents to the coating.
The surface treatment and anti-corrosion properties of motorcycle aluminum alloy forgings are the key factors affecting motorcycle life and safety. Through reasonable surface treatment and high-quality anti-corrosion measures, the corrosion resistance of aluminum alloy forgings can be significantly improved to ensure the safe operation of motorcycles and extend their service life.
