FINISHES

What is passivation?

Passivation is treating a metal surface to make it more corrosion-resistant. The process involves the creation of a thin layer of oxide on the metal surface that acts as a barrier against corrosive agents such as oxygen and water. This layer is typically formed by immersing the metal in an acid bath, which causes a chemical reaction that generates the oxide layer. It is commonly used in manufacturing medical instruments, aerospace components, and food processing equipment, where corrosion resistance is critical for long-term reliability. The process is also widely used in the automotive and electronics industries to protect parts and components from wear and tear caused by exposure to harsh environments.

Our passivation process:

Our process involves several steps to ensure the protection and enhancement of metal parts.

  1. Firstly, the components are thoroughly cleaned to remove any impurities or contaminants.
  2. Next, we apply the solution, typically a nitric acid solution, to the parts, removing any surface iron that has come into contact with the metal during manufacturing. The solution also removes any machining or grinding residue that could be potential corrosion sites.
  3. After applying the solution, the parts are rinsed with water to remove any excess residue.
  4. Finally, the components are dried and inspected to ensure success.

We carefully tailor the process to the specific materials and parts we work with, ensuring the method effectively enhances the materials’ quality, reliability, and longevity.

Why choose passivation for your next project?

It removes free iron and contaminants from parts to create a protective layer that offers corrosion resistance. This extends the lifespan and durability of metal parts, improves their appearance, and reduces the need for repairs and replacements, resulting in cost savings. Moreover, the process is a simple and cost-effective process that can be performed on various metals, making it an attractive option for businesses to enhance the quality and reliability of their products.
