The surface treatment methods of motorcycle forgings mainly include the following: Chromium Plating: The surface of the forgings is deposited by the electroplating process to improve the corrosion resistance of the forgings, while increasing its gloss and decoration. Sandblasting: The use of sandblasting machine will spray high-speed flow of abrasive particles on the surface of the forging to remove surface impurities, oxides and burrs, making the surface of the forging more smooth. Electrophoretic Coating: the forgings are immersed in a specific coating, and the coating is attached to the surface of the forgings through the action of electric field to form a uniform coating, which has good corrosion resistance and decorative effect. Hot-dip Galvanizing: The forging is immersed in a molten zinc solution to form a zinc layer on the surface. Hot-dip galvanizing can improve the corrosion resistance and prolong the service life of forgings. Coating: By spraying, brushing and other methods, a special layer of coating is formed on the surface of the forging, such as paint coating, ceramic coating, etc., to provide specific functions or decorative effects of the forging. Nitriding: The surface of the forgings is placed in nitriding agents such as ammonia, and nitriding is processed at high temperatures to form a nitriding layer with higher hardness to improve the wear resistance and corrosion resistance of the forgings. Salt Bath Carburizing: The forgings are immersed in a salt bath containing carbon sources and carburized under high temperature conditions to make the surface of the forgings carbon-rich and form a layer of carburizing with high hardness to improve the wear resistance and strength of the forgings. Different surface treatments can be selected according to the requirements of the forging and the different use environment to meet the needs of the function, appearance and durability of the forging.
