Chromate conversion coatings are surface treatments used across industries to enhance corrosion resistance and promote adhesion on various metals, including aluminum, magnesium, zinc, and zinc-plated steel. The process involves cleaning the metal substrate and applying a chromate coating, typically containing hexavalent or trivalent chromium. This coating chemically reacts with the metal surface, forming a protective layer that acts as a barrier against corrosion, ensuring the longevity and durability of metal components in harsh environments.
Alodine
Alodine (also known as chem film), specifically applied to aluminum surfaces, is a surface treatment method prevalent in aerospace, automotive, and electronics industries. The Alodine process involves cleaning the aluminum substrate and applying a chromate conversion coating, often containing hexavalent chromium. This coating chemically reacts with the aluminum, forming a thin, adherent layer that enhances...
Iridite
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...
Zinc Chromate Coatings
Chromate conversion coatings applied to zinc-plated substrates, commonly referred to as zinc chromate coatings, serve to enhance the corrosion resistance and adhesion properties of the zinc-plated surface. The process typically involves electroplating the substrate with a layer of zinc, creating a sacrificial barrier against corrosion. Subsequently, a chromate conversion coating is applied to the zinc-plated...
