Introduction Chromate Conversion Coating

Anodising makes metal better by forming a layer of aluminum oxide on its surface. Type II is good for general use and offers a uniform oxide layer that resists corrosion. It is commonly used in construction and electronics. Type III creates a harder oxide layer than Type II, making the metal more resistant to wear. It is ideal for high-performance areas like aerospace and automotive engines. Type II is good for general use. It creates a protective oxide layer that fights corrosion. The choice of type depends on the specific application and the nature of the material.

Design Considerations

Material selection: Choose aluminum alloys that can be anodized. Take into account the color and texture of the alloys after oxidation.

Surface design: To prevent color differences in the oxidized layer, it’s important to have a flat surface. Additionally, it’s best to avoid closed recesses so liquids can flow smoothly during oxidation.

Shape of edges: Rounded edges help to achieve a uniform oxidation.

Insulating properties: In the design, we need to pay attention to maintaining the electrical conductivity of the part. Anodising has insulating properties that will insulate your part.
