Protection method of spring surface:
The surface of the spring can generally be treated, such as blackening, phosphating, electroplating, spraying, etc. In recent years, Dacromet’s protective layer has appeared with excellent corrosion resistance, which is 7~10 of the corrosion resistance of traditional electroplating layers. Double, there is no hydrogen embrittlement of electroplating process. And strong adhesion, especially suitable for surface protection of elastic materials.
The surface of the product treated by Dacromet is silvery white. The main characteristics and use of the surface treatment are corrosion resistance. Oxidation treatment, common spring protection is generally kept in the air for 3 months, and electroplating is used to protect 3 in the general air medium with higher protection. Month-2 years. Phosphating treatment has higher anti-embroidery ability than oxidation treatment, and can withstand high temperatures of 400℃. It is generally used for the protection of important parts such as artillery and gun parts, or as the pre-treatment of other protective layers. Non-metallic protective layer, paint, spray , Electrophoretic paint and other anti-corrosion capabilities, a wide range of applications, and strong anti-corrosion capabilities. At present, the special anti-rust oil protection used for the pretreatment of automobile surfaces is often used for refrigerator compressor springs without hydrogen embrittlement, simple process, environmental protection and pollution-free produce.
