In the spring in use, store can occur because of various factors lead to the phenomenon such as corrosion, so to be surface anti-corrosion treatment, increase the service life of the spring.
How to carry out anti-corrosion treatment on the surface of the spring?
To summarize: (spring manufacturer
1)
Streamline the surface of the reed to defend dumped goods number, like electricity gold plated hard to impress the
hardware layer, electroplating process cover not only can cover the spring would not be erosion, in addition to improved streamline the shapes of reeds, hardware, electroplating process but also to the next level reduce spring's basic laws, such as three conditions surface strength, increase the wear resistance force, improve the thermal comfortable housing project, make provisions before troubles occur radiation FengBaoYuShi, etc.
But if only to resolutely du * broken the erosion of reed, general should use phosphating layer want cadmium plating processes.

2)
To like a duck to water cut of spring corrosion protective properties of cadmium plating layer, can be in progress after plating passivation of bidding: zinc and cadmium plating thick shura maintenance energy voice of god.
Thickness of prioritize masher should act according to use when the natural environment to pick, hot dip galvanized layer strength cited in the range of 6 ~ 24 mu m option;
Cadmium plating layer thickness presented in the range of 6 ~ 12 mu m option.

3)
Form nearly pressure spring of hot galvanizing layer passivation of the left goods, after passivation can breed seen coating surface of the bunker basic law and exploded.
Forgive and forget in maritime or high temperature, and the surface of the touch, the way of the spring, at 70 ° C in use in the boiling water pressure springs, cadmium as stable, strong corrosion resistance characteristics.

Cadmium plating than zinc plating smooth into eyes, soft, ductility is better than zinc, coating small hydrogen brittleness, * suitable for lose spring as a protective layer, but there is little to mark parts of cadmium cadmium salt, use the value of money, and side effects, the air pollution is very hot, spring manufacturers therefore restricted in use, so the most only in airlines, ship and electronics industry production common protection measures is cadmium plating layer.
