Plating coating on common spring's surface to improve the quality of the surface and also increase the anti-rusty ability.
Improve the surface hardness, increase the wear resistance, improve thermal stability, prevent ray corrosion, etc.. However, if only for the corrosion of the spring, the general use of zinc plating layer。Zinc is more stable in dry air, almost does not change, not easy to change color. White film will form a layer of Zinc Oxide or carbon zinc carbonate in the humid air. This layer of dense film can prevent continued corrosion. Therefore, the zinc coating is used to prevent the corrosion of the spring under general atmospheric conditions. Where is in contact with sulfuric acid, hydrochloric acid, caustic soda solution, and spring work in three, sulfur dioxide atmosphere in humid air, do not take zinc coating.
