About Black Oxide

Black oxide, also known as blackening (similar to Alodine) , is a chemical conversion coating used to provide a layer of black corrosion protection on various types of metal surfaces, particularly steel and iron.

The process of black oxide involves immersing parts in a hot bath containing various chemicals to convert the surface of the material into magnetite, thereby forming a black oxide layer. This process will not have a significant impact on the size of the parts, so there is no need for special steps to cover or cover the parts.

In addition, the black oxide immersed in oil can provide higher corrosion resistance. Because after the black oxide, a layer of oil film is usually applied, which helps to provide additional corrosion protection and reduce contact between the metal surface and the external environment.
