As one of the key parts of motorcycle copper alloy forgings, its surface treatment technology is very important to improve product quality and enhance performance. In this paper, the surface treatment technology of motorcycle copper alloy forgings will be analyzed in detail.
- Pickling and cleaning: In the manufacturing process of motorcycle copper alloy forgings, some oxides, rust or other impurities will be produced. Pickling cleaning is one of the most basic surface treatment methods, which can remove these impurities from the surface of copper alloy forgings by using an acidic solution to ensure the smooth progress of the next process.
- Anodizing: Anodizing is a common surface treatment method, which is suitable for improving the corrosion resistance, wear resistance and heat resistance of copper alloy forgings. By adding a specific additive to hydrochloric acid or sulfuric acid, a dense and uniform oxide film is formed on the surface of copper alloy forgings. This oxide film not only has the characteristics of corrosion resistance, but also plays the role of decoration and prevention of surface scratches.
- Electrophoretic coating: Electrophoretic coating is a surface treatment method with good adhesion and uniform coverage. By applying a direct current electric field on copper alloy forgings, solid particles are suspended in the electrolyte and deposited on the surface of copper alloy forgings to form a coating under the action of electric field. Electrophoretic coating can not only provide certain anti-corrosion protection, but also increase the decoration of motorcycle copper alloy forgings.
- Sandblasting treatment: Sandblasting is a method of physical erosion of oxides, stains and rough layers on the surface of copper alloy forgings through high-speed abrasive particles. Sandblasting can effectively improve the surface quality and finish, and provide a good basis for subsequent surface treatment methods.
- Electroless plating: Electroless plating is a surface treatment method of depositing metal on the surface of copper alloy forgings using the principle of electrochemistry. It does not require an external power supply, by controlling the reaction conditions in a specific electrolyte, the metal ions are reduced and deposited on the surface of the copper alloy forgings, and the effect of increasing wear resistance and decoration.
In short, the surface treatment technology of motorcycle copper alloy forgings includes pickling cleaning, anodizing, electrophoretic coating, sandblasting and electroless plating. Choosing suitable surface treatment technology can improve the performance and quality of motorcycle copper alloy forgings, extend their service life, and make the product more beautiful.
