Chromate Passivation – Eminent Surface Metal Coating

Chromate passivation is a chemical treatment applied to metal surfaces, primarily aluminum, to enhance their corrosion resistance and durability. This process involves immersing the metal in a chromate solution, which forms a protective, passive oxide layer on the surface.

The resulting coating not only protects the metal from oxidation and environmental damage but also improves its adhesion properties, making it an ideal base for subsequent painting or coating. Chromate passivation is widely used in various industries, including automotive, aerospace, and electronics, where enhanced corrosion protection and surface preparation are critical. The process can produce a distinctive, aesthetically pleasing finish in a range of colors, from clear to iridescent yellow and green.

Despite its effectiveness, modern chromate passivation techniques are increasingly focused on reducing environmental and health impacts, adhering to stringent regulations regarding the use of hexavalent chromium. Our chromate conversion coating complies with the requirements of MIL-DTL-5541, and we have extensive experience applying it to parts used in the demanding aerospace, oil and gas, and power generation industries.
