NOVELTY - The ferrous metal surface nitriding anti-corrosion method involves (1.1) adding the fittings in the cleaning tank to remove oil stains, (1.2) taking out and blow dry, (1.3) adding in a nitriding furnace and the temperature of the nitriding furnace is 450-480 degrees C and filling the nitriding furnace with nitrogen and oxygen for 5-8 hours, (1.4) preliminary completing nitriding fittings, (2.1) preparing anti-corrosion paint, (2.2) applying the anti-corrosive coating to the nitriding fittings, and (3) completing. USE - Ferrous metal surface nitriding anti-corrosion method. ADVANTAGE - The nitriding anti-corrosion method modifies the surface of the fittings to improve the surface quality of the product. The graphene anti-corrosion coating is reliable and convenient.
