1. Sandblasting (shot peening)
The process of cleaning and roughening metal surfaces by the impact of high-velocity sand streams.
Surface treatment of aluminum alloy parts in this way can make the surface of the workpiece obtain a certain degree of cleanliness and different roughness, improve the mechanical properties of the surface of the workpiece, thereby improve the fatigue resistance of aluminum alloy parts, and increase the friction between the workpiece and the coating. Adhesion, prolongs the durability of the coating film, and is beneficial to the leveling and decoration of the coating.
2. Grinding
A machining method that uses mechanical, chemical, or electrochemical action to reduce the surface roughness of aluminum alloy parts to obtain a bright, flat surface. According to the editor of Transit Aluminum, the polishing process is mainly divided into mechanical polishing, chemical polishing and electrolytic polishing. After mechanical polishing and electrolytic polishing, aluminum alloy parts can approach the mirror effect of stainless steel. This process gives a sense of high-end simplicity and a stylish future.
