Blackening / 发黑处理剂

 
Black Oxide or blackening is a conversion coating for ferrous materials,copper and copper based alloys, zinc, powdered metals, and silver solder. It is used to add mid corrosion resistance and for appearance. To achieve maximum corrosion resistance the black oxide must be impregnated with oil or wax. One of its advantages over other coatings is its minimal buildup.
