What are the types of corrosion of
spring?
Manufacturer of spring spring corrosion according to the reflection of the species can be divided into chemical corrosion and electrochemical corrosion.
They are all spring surface of metallic material molecules shift or electronic devices and loss as ionization results.
In the manufacture, storage and application of spring in the whole process, often by the surrounding material corrosion.
Because spring on elastic give full play to the work when it is, the spring is lack of elasticity changes after corrosion.
Thus avoid corrosion can ensure that spring spring work smoothly, and increase its life.
If the surface of the spring only simple metal material and the surrounding material produces chemical reaction, cause corrosion according to chemical corrosion and spring.
Such as spring in very dry air oxidation in the atmosphere of mania into air oxidation film, and the spring in the electrolyte in the liquid and residue produced in the liquid or the liquid chemical shift, belongs to chemical corrosion.
Spring by chemical etching is small, slow, and the electrochemical corrosion is the key, broad.
But in general chemical corrosion and electrochemical corrosion is the other entities.
If spring and touch, electrolyte solution for micro cell corrosion caused by the role of electrochemical corrosion.
Such as spring touch with acid saline alkaline or acid solution, such solution is full of electrolyte solution, because weakness or residue on the surface of the spring and produce electric potential difference is not the same power level that spring continue to suffer from an electrolytic corrosion;
Such as spring in damp atmosphere again, because the water vapor in the atmosphere of spring into water or water droplets on the surface, and increase of corrosion in gas gas (
Such as organic sulfur dioxide and hydrogen chloride in waste gas or deep-sea atmospheric corrosion resistance, etc. )
Dissolve in shrink water or water droplets in the electrolyte solution.
Then add spring metal residue or shortcomings can also produce electric potential difference is not the same power level, spring also caused an electrolytic corrosion.
This is electrochemical corrosion.
