Product Description

Black oxide is a cost-effective way to finish your part by Techno Surface finish Services.
Black oxide is a functional surface finish formed by immersing parts into a hot alkaline bath. Typically matte black, this coating reduces glare and enhances corrosion resistance.

What is Black Oxide Coating?

Black oxide, sometimes referred to as blackening, is a low-cost finishing method for adding corrosion resistance, reducing reflection, and enhancing the appearance of parts. Black oxide conversion coatings are created by submerging ferrous parts in a hot alkaline aqueous salt solution bath. Once immersed, a chemical reaction is created on the surface of the parts, which results in a magnetite coating. As a final step, an after-finish of oil, wax, or lacquer is applied for added corrosion resistance.
