Iridite, primarily used for treating aluminum surfaces, is a significant surface coating process employed in diverse industries, including aerospace and electronics. The Iridite process involves preparing the aluminum substrate by cleaning it thoroughly and then applying a conversion coating free of hexavalent chromium. This coating chemically reacts with the aluminum, creating a thin, protective layer that enhances corrosion resistance and facilitates superior adhesion for subsequent coatings.

The Iridite-treated aluminum surfaces exhibit heightened durability, essential for components exposed to challenging environments. The conversion coating acts as a reliable barrier against corrosion, ensuring the prolonged integrity of aluminum parts. While the process can impart different colors to the treated surface, ongoing research explores alternatives such as trivalent chromium to address environmental concerns associated with hexavalent chromium, aligning Iridite with evolving eco-friendly practices. In aerospace and electronics applications, Iridite stands as a crucial method for enhancing the performance and reliability of aluminum components while meeting industry standards.
