Product Details

We know that most compression springs are made of metal, so the surface is easy to rust. Therefore, we must consider antirust treatment on the spring surface. What is the surface treatment of compression spring? Which method will we use? The following describes the surface treatment method of Electroplating Cylindrical Spring:

 

H96e61a6687db47e6b57544bda156227cZThe thickness of zinc and cadmium coatings determines the protective ability. The thickness is generally selected according to the working environment during use, and the hardness of zinc coating is recommended to be 6 ~ 24 μ M; It is suggested to be between 6 and 12 μ Select the thickness of cadmium plating layer within M. After passivation of the zinc coating of general pressure spring, passivation can improve the protective performance of the coating and increase the appearance of the surface. In the ocean or high-temperature atmosphere, as well as the compression spring in contact with seawater, the pressure spring used in 70 ° C hot water has stable cadmium and strong corrosion resistance.

 

Cadmium coating is brighter and more beautiful than zinc coating, with soft texture, better plasticity than zinc and less hydrogen embrittlement. It is most suitable for compression spring as protective layer. However, cadmium is scarce and expensive. Cadmium salt is toxic and has serious environmental pollution. Therefore, the use is limited. Therefore, cadmium coating is only used for compression springs used in aviation, navigation and electronic industry.

 

The above is the surface treatment method of electroplating spring. Warmly welcome to Contact Us for more information!
