The ceramic sand blasting process uses the impact of high-speed sand flow to clean and roughen the metal surface. The surface treatment of aluminum parts in this method can obtain a certain degree of cleanliness and different roughness on the surface of the workpiece, so that the mechanical properties of the workpiece surface can be improved, thus improving the fatigue resistance of the workpiece and increasing the gap between it and the coating. The adhesion of the coating prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating.
Anodic oxidation of ceramic sand blasting process refers to the electrochemical oxidation of metals or alloys. Under the corresponding electrolyte and specific process conditions, aluminum and its alloys form a layer on the aluminum product (anode) due to the action of the applied current. process of oxide film.
Anodizing can not only solve the defects of aluminum surface hardness and wear resistance, but also prolong the service life of aluminum and enhance the aesthetics. It has become an indispensable part of aluminum surface treatment and is currently the most widely used and very successful. craft.
In theory, micro-arc oxidation of ceramic sand blasting process is suitable for all metal industries, but objectively, because micro-arc oxidation requires too much electric power, it is more suitable for small workpiece industries. Aerospace and IT products just meet micro-arc oxidation. application target. It has the advantages of simple process, small footprint, strong effect, high efficiency, suitable for large-scale production, and low environmental pollution, so it is currently in a period of vigorous development in many industries.
