This chromate conversion coating is a type of coating used to passivate aluminum, zinc, cadmium, copper, silver, magnesium, and tin alloys.
It is primarily used as a corrosion inhibitor, primer, decorative finish and it can retain electrical conductivity.
The process is named after the chromate found in the chromic acid used in the bath, more commonly known as trivalent chromium.
Trivalent chromate is an iridescent conversion that can exhibit different hues. This is considered normal, when applying iridescents.
Olive drab is generally designed for higher corrosion protection and rust inhibitor.
Olive drab chromate is also a iridescent chromate, that may exhibit different hues. This is considered normal, when dealing with iridescents.
Typically military or automotive applications is appropriate for olive drab plating, where exposure to corrosion is a high factor.
The passivate process is designed to remove foreign metals and oils (usually from machining) from the surface of stainless steel. The end finish will not change the dimension of the part nor the overall appearance of the base metal. Passivation purifies the surface of a machined part and therefore improves corrosion resistance.
