Surface treatment of springs


Spring surface treatment


HalogenateA phosphate film is attached to the metal surface to enhance the adsorption of oil, which can make the anti-rust ability and electrical insulation better.
RustproofingRustproofing can make the combination of spring and zinc better. Better rust resistance than Electrogalvanizating.
Nickel ElectroplatingElectroplated nickel can prevent rust and be beautiful. Commonly used on battery springs.
Tin ElectroplatingTin plating is a coating with good solderability and certain corrosion resistance.
ElectrogalvanizationEffective anti-rust ability after electroplating. It is not easy to be corroded in acid and alkali. Ductile after electroplating. Can also be bent. Can be electroplated in various colors
Chromium EectroplatingUsually to increase surface hardness and friction resistance. Because chrome is not easy to change color, it is necessary to use the spring in the appearance part. Rust resistance is not as good as galvanized. Expensive.
Gold ElectroplatingIn order to have good electrical conductivity.Expensive.
E-CoatingIt can make the appearance similar to baking paint, the color is uniform and the rust resistance is good, and it is suitable for use on products that require appearance.
Surface PassivationApplied to stainless steel wire, the stainless steel surface is attached with a film to increase corrosion resistance and rust resistance.
Powder CoatingVarious colors can be adjusted,
The surface of the spring can be painted with a layer of 50-300μm.
Shot PeeningSpray spring products with small beads to eliminate stress and increase the service life of springs, often used on compression springs.
GrindUse a grinder to grind the plane at both ends of the compression spring, and the spring can be evenly stressed without tilting when the spring is stressed.
Black OxideBlack with oil on the surface. Can prevent rust. But the effect is limited. To achieve the best results, it is recommended to add anti-rust oil to achieve the best results. Cheap.
