Anodising is an electrochemical process that improves the physical and chemical properties of aluminium and its alloys by forming an oxide film on their surface. The process is carried out by applying an applied electric current to the aluminium product (acting as the anode) under the appropriate electrolyte and specific process conditions, thereby forming an oxide film on its surface.
Anodising has a wide range of applications and the main advantages include.
1. Good processability: anodized aluminium sheet has good decorative properties and moderate hardness, which can be easily bent into shape for continuous high-speed stamping and conveniently processed directly into products without complicated Surface treatment, greatly shorten the production cycle and reduce production costs.
2. Good weather resistance: anodized aluminium sheet has excellent corrosion resistance, the standard thickness of oxide film (3μm) of anodized aluminium sheet used indoors for a long time without discolouration and corrosion, No oxidation, no rust. The anodized aluminium sheet with thickened oxide film (10μm) can be used outdoors and can be exposed to sunlight for a long time without discolouration.
3. Strong sense of metal: the surface hardness of anodized aluminium plate is high and reaches the gem level, good scratch resistance, no paint covering the surface, retaining the metallic colour of aluminium plate, highlighting the modern sense of metal, improving the grade and quality of products. metal sense, improve product grade and added value.
4. High hardness of the barrier layer: the porous oxide film has very high hardness, which can exceed corundum, with good wear resistance, corrosion resistance and chemical stability. The morphology and size of the holes can be changed in a wide range with different electrolysis processes, and the thickness of the film can be adjusted.
5. Simple preparation process: anodic oxidation does not require high environmental conditions and equipment, and the preparation process is relatively simple, suitable for mass production and application.
In summary, anodic oxidation technology significantly improves the hardness, wear resistance, corrosion resistance and chemical stability of aluminium and its alloys by forming a solid oxide film on its surface, while simplifying the production process and reduces the cost, so it is widely used in various fields requiring surface hardening and corrosion resistance protection.
