Anodic oxidation is an electrochemical reaction process. By making a metal workpiece act as the anode in an electrolyte and under the action of an external current, a stable and dense oxide film is formed on its surface. This film is closely bonded to the substrate, is not easy to peel off, and has excellent physical and chemical properties.The following are several main advantages of anodizing:
1. Enhance corrosion resistance
The aluminum oxide film formed by anodic oxidation has excellent corrosion resistance. Compared with untreated aluminium materials, anodized aluminium exhibits stronger oxidation resistance in various environments, such as damp, acidic or alkaline conditions. This makes anodized aluminum widely used in industries such as aerospace, automobiles and construction, which can effectively extend the service life of products.
2. Enhance wear resistance
The hardness of the anodic oxide film is usually higher than that of aluminum itself, which can significantly enhance its wear resistance. This characteristic makes anodized aluminum of great value in the manufacturing of mechanical parts and tools, capable of withstanding higher wear and impact.
3. Good adhesion
The surface of aluminum after anodizing treatment has good adhesion and can form a firm bond with coatings, adhesives and other materials. This is of great significance for the subsequent spraying, coating and assembly processes, and can ensure the quality and performance of the final product.
4. Enhance surface treatment
In addition to providing protection, it also enhances the aesthetic appeal of the substrate surface. Anodized surface treatment can almost achieve all surface textures, from matte to high gloss. Therefore, countless color options and customizations can also be provided. Meanwhile, its appearance can remain colorfast for a long time. In addition, this surface treatment can be applied to any complex and delicate component or product.
5. Durability and lifespan
Anodic oxidation coating is a kind of hard oxide coating that can enhance hardness, wear resistance and corrosion resistance. It covers all sharp corners, edges and complex areas. Unlike other coatings, you also do not have the risk of bonding failure. All these reasons extend the service life of the anodized coating, thereby prolonging the service life of the underlying components.
Anodizing treatment is highly suitable for non-ferrous metals such as aluminium, titanium and zinc, being both wear-resistant and aesthetically pleasing. The flexibility in thickness and appearance (color) makes it an ideal choice for almost all industries that use aluminum alloy components.
