How to protect the surface of the spring
Author:
The surface of the spring can generally be treated, such as black (blue), phosphating, electroplating, plastic spraying, etc. In recent years, there has been a zinc-chromium film. Dacromet protective layer has excellent corrosion resistance, which is 7-10 times of the corrosion resistance of the traditional plating layer, and there is no hydrogen embrittlement of the electroplating process. And strong adhesion, especially suitable for surface protection of elastic materials.
The surface of the Dacrome-treated product was silvery white. The main characteristics of surface treatment and use of corrosion resistance oxidation treatment commonly used spring protection is generally kept in the air for 3 months, electroplating is used to protect the general air medium for 3 months to 2 years. Phosphating treatment has a higher anti-embroidery ability than oxidation treatment, and can withstand a high temperature of 400 ℃. It is generally used for important parts protection such as artillery gun parts, or pretreatment non-metallic protective layers, paint, plastic spraying, electrophoretic paint and other protective layers. It has strong anti-corrosion ability and wide application range, especially electrophoretic paint. At present, special anti-rust oil for pretreatment on automobile surfaces is commonly used for protection of refrigerator press springs without hydrogen embrittlement, simple process, environmental protection and pollution.
