Spring Surface Treatment Prolongs Service Life

In contact with acidic or salt solutions, which are electrolytes, electrodes with different potential differences are formed due to defects or impurities on the surface of the spring, resulting in continuous electrolytic corrosion of the spring; For example, when a spring is in a humid atmosphere, the water vapor in the atmosphere condenses into a water film or water droplet on the surface of the spring, and corrosive gases in the atmosphere (such as sulfur dioxide and hydrogen sulfide in industrial waste gas or salt mist in the ocean atmosphere) dissolve in the water film or water droplet to form an electrolyte. In addition, impurities or defects in spring metal can also form electrodes with different potential differences, which are often corroded by surrounding media during manufacturing, storage, use, and other processes. Due to the fact that springs rely on elastic force during operation, their elasticity will change and lose function after being corroded. So preventing corrosion of the spring can ensure its stable operation and extend its service life.
