Surface Finishes and Post-Processing Enhancements for CNC Aircraft Parts

After the CNC machining aerospace parts process, surface finishes and post-processing enhancements play a crucial role in the overall quality and performance of the part. At TMC Technologies, we understand that the right surface finish not only improves the aesthetics of a part but also boosts its durability, corrosion resistance, and maintenance needs. We offer a variety of post-processing techniques, including anodizing, passivation, polishing, and powder coating.

Anodizing Process for Aerospace Parts

Anodizing is a process that helps protect aerospace parts from corrosion by creating a uniform oxide layer on the part’s surface. The part is immersed in an electrolyte solution, leading to the formation of this protective layer.

There are two types of anodizing used on aerospace parts. Type II, which forms a decorative layer, and Type III, which creates a more protective hard coat layer. Although Type II anodizing offers an aesthetic appeal, it leaves the part susceptible to corrosion. Therefore, for parts needing more protection, we use Type III anodizing, which provides a thicker, harder coating that is more resistant to wear and tear.

Passivation and Polishing Techniques for Aerospace Components

Passivation is another post-processing method we use at TMC Technologies. This process enhances the surface quality and functionality of components by improving their corrosion resistance and reducing surface impurities. Consequently, aerospace parts require less maintenance over time.

Polishing, on the other hand, is a simple but effective technique that results in a smooth, attractive finish. This process involves using abrasion to remove surface irregularities, making the part smoother and more pleasing to the eye. Additionally, polishing increases the part’s durability by reducing the chances of chipping or cracking. However, it’s worth noting that polishing can be time-consuming and may add to the overall cost of the part.

The Role of Powder Coating in Aerospace CNC Machining

Powder coating is a popular surface finish for metallic aerospace parts. This process involves applying a free-flowing, dry powder to the surface of a part, which is then cured under heat to form a hard, protective layer.

Powder-coated aerospace parts are resistant to scratches, fading, and chipping, making this finish ideal for parts that are exposed to harsh environmental conditions. Additionally, powder coating offers a wide range of color options, giving manufacturers the flexibility to match the aesthetic requirements of any project.

At TMC Technologies, we prioritize quality and precision in every step of the CNC machining process, from initial design and production to post-processing enhancements.
