An iron oxide surface acts like a car battery, with the surface divided into microscopic anodes (+) and cathodes (-). In condensate systems, iron acts as an anode so that it is oxidized (i.e., gives its electrons to the cathode). The cathode in pure water is a proton or hydrogen ion (H ... WebJan 12, 2024 · Black oxidation treatment is a surface coating treatment method commonly used by military cutting tools because it can eliminate reflection. After the Black Oxide process is complete, the metal hardware will have a smooth, dark finish. This finish is typically applied to steel or brass hardware and can be used to create a sleek, modern look. flyibonair
