Chem film vs clear chromate
WebChromate Conversion Coating is a process that converts the aluminum surface properties, unlike plating, which applies a coating onto the aluminum’s surface. It is typically used to passivate magnesium, copper, silver, tin, zinc, aluminum, and steel alloys. It can also be used as a decorative finish, primer, corrosion inhibitor, or to retain ... WebIn contrast, Alodine (chem film) coatings do NOT apply electrical current to the aluminum. The metal is immersed in a tank, often at room temperature. Compared to anodizing, …

Chromating is often performed on galvanized parts to make them more durable. The chromate coating acts as paint does, protecting the zinc from white corrosion, thus making the part considerably more durable, depending on the chromate layer's thickness. The protective effect of chromate coatings on zinc is indicated by color, progressing from clear/blue to yellow, gold, olive drab and black. Darker coatings generally provide more corrosio…
