Anodisation
Anodisation is an electrochemical process used to control the oxide layer on the surface of an aluminum part.
The properties thus obtained are varied and interesting:
• Resistance to corrosion: By isolating the matter from the environment, the anodic layer protects the part from corrosion. The finish of the part is then preserved;
• Coloration: An anodization process also allows us to color the part in a variety of colors. The coloration of the part is very durable and outlasts most other paints and coatings, while offering an interesting texture and finish;
• Abrasion resistance: The anodic layer is much harder than the aluminum itself (200 to 800 Vickers compared to 120 for standard aluminum (6061-T6)),
the anodised part is extremely resistant to wear and abrasion. Furthermore, the hardness is limited to the oxide layer and the other properties of the part are preserved;
• Electrical Insulation : The anodic layer is dielectric, meaning that it does not conduc electricity;
•Improved adhesion of coatings : The anodic layer is porous, which increases the adhesion of the different coatings that can be applied to the part (in the case of unsealed anodizing only);
• Masking: It is possible to mask certain areas of the parts to keep the anodic layer from forming on selected surfaces (be they interior, a hole for instance, or exterior). This is interesting if the properties of the anodisation process are not desirable on the whole part.
