3. What is the principle of Black Oxidation?

The principle of black oxidation blackening surface treatment is based on the oxidation reaction between metal and oxygen, forming a dense oxide film. This type of oxide film is usually rich in metal oxides (such as Fe3O4), which have good corrosion resistance and wear resistance, and can effectively protect the metal surface from further oxidation and corrosion.
