Understanding Clear Zinc Plating Dekalb Metal Finishing

The first step is to add the zinc plating, through the use of electrical current. The second step is to treat the plated metal with a chemical passivate which adds color. These solutions are referred to as chromates (hex chrome) or passivates (tri chrome). To create a clear finish, a clear passivate is used.

Anodizing - Wikipedia

Zinc. Zinc is rarely anodized, but a process was developed by the International Lead Zinc Research Organization and covered by MIL-A-81801. A solution of ammonium phosphate, chromate and fluoride with voltages of up to 200 V can produce olive green coatings up to 80 μm thick. The coatings are hard and corrosion resistant.

Zinc Coatings for Fasteners American Galvanizers

09-10-2018  High temperature galvanizing (delta galvanizing) is a hot-dip coating process where steel is dipped in a zinc bath at 1040 - 1165 °F (560 - 630 °C) to form a coating comprised of a thin gamma layer with a compact delta layer on top. As a result, a very hard, rough, and thin coating is produced with similar properties to a traditional hot-dip ...
