Motorcycle magnesium alloy forging is one of the key components commonly used in motorcycle manufacturing, which has high requirements on surface treatment technology while ensuring strength and lightweight. This paper will explore the surface treatment technology of motorcycle magnesium alloy forgings.
- Anti-corrosion treatment
Magnesium alloys are susceptible to oxidation and corrosion, so it is essential to prevent corrosion during surface treatment. Common corrosion prevention methods include electroplating, anodizing and chemical coating. Electroplating can use nickel, chromium, zinc and other metals to form a protective layer, which can effectively increase the corrosion resistance of the material. Anodizing improves corrosion resistance by forming a dense oxide layer on the surface of magnesium alloys. Chemical coating is the use of a specific solution for surface treatment, to produce a corrosion resistant film. - Surface modification treatment
In order to improve the surface properties of motorcycle magnesium alloy forgings, many methods can be used to modify the surface. Among them, sandblasting and polishing is one of the most common surface treatment methods. Sand blasting can remove the surface oxide layer and impurities and improve the surface finish. Polishing can make the surface smooth, bright, and enhance the appearance of the motorcycle texture. - Coating technology
Coating technology is one of the important means for surface treatment of motorcycle magnesium alloy forgings. By choosing the appropriate coating material, it is possible to increase the hardness, wear and corrosion resistance of the surface, as well as improve lubrication and reduce friction. Common coating technologies include electrophoretic coating, spray coating, thermal spraying, etc. Electrophoretic coating can form a uniform, dense coating with excellent corrosion resistance. Different coating materials such as epoxy, polyester and polyester metal can be selected according to the requirements of the spraying technology. Thermal spraying technology can form a coating on the surface that is resistant to high temperature and wear. - Surface nano treatment
In recent years, surface nano treatment technology has been gradually applied to the surface treatment of motorcycle magnesium alloy forgings. The hardness, wear resistance and corrosion resistance of the surface can be improved by nano treatment. Common nanocrystalline treatment methods include nanocrystalline material spraying treatment, surface nanocrystalline treatment and so on. Nanocrystalline material spraying treatment Nanocrystalline material is formed on the surface of alloy by high-speed spraying processing method to improve the surface hardness and wear resistance. The surface nanocrystalline treatment is to transform the surface of the alloy through a special process to improve the surface properties.
In summary, the surface treatment technology of motorcycle magnesium alloy forgings involves anti-corrosion, surface modification, coating and surface nano treatment. Selecting the appropriate surface treatment method and process can improve the surface properties of motorcycle magnesium alloy forgings such as corrosion resistance, wear resistance and permanence, improve the overall quality of motorcycle and extend its service life. With the continuous progress of science and technology, it is believed that the study of motorcycle magnesium alloy forging surface treatment technology will bring more innovation and development to the motorcycle manufacturing industry.
