The surface treatment process of wheel bolts usually includes the following:
1.Galvanizing: Immerse the surface of the bolt in a zinc solution and form a protective layer of zinc on the bolt surface through electrochemical reactions. This treatment process can improve the corrosion resistance of bolts and extend their service life.
2.Heat treatment: Improve the mechanical properties of bolts by heating them to a certain temperature and then rapidly cooling them. Common heat treatment methods include quenching, tempering, etc., which can improve the strength and hardness of bolts.
3.Rust prevention treatment: Use rust inhibitors or coatings to protect the surface of wheel bolts from oxidation and corrosion. Common rust prevention methods include spraying anti rust paint, applying anti-corrosion coatings, etc.
4.Electroplating: Immerse the bolt in an electrolyte to form an electrochemical reaction of metal ions between the anode and cathode, causing the metal ions to deposit on the surface of the bolt, forming a metal film with corrosion resistance, brightness, and aesthetics.
5.Dacromet:Place the bolt components excited by water in a bath containing Dacromet solution for immersion plating. Dacromet solution is an inorganic coating solution containing zinc, aluminum, and chromium.
