Corrosion of Salt Spray Test Chamber
Latest company news about Corrosion of Salt Spray Test Chamber

Corrosion is the damage or deterioration of materials or their properties caused by the environment. Most of the corrosion occurs in the atmosphere, which contains corrosive components and factors such as oxygen, humidity, temperature changes and pollutants. Salt spray corrosion is a common and most destructive atmospheric corrosion.


The salt spray mentioned here refers to the chloride atmosphere, and its main corrosive component is the chloride salt in the ocean—sodium chloride, which mainly comes from the ocean and inland saline-alkali areas. The corrosion of salt spray on the surface of metal materials is caused by the electrochemical reaction between the contained chloride ions penetrating the oxide layer and protective layer of the metal surface and the internal metal.


At the same time, chloride ions contain a certain amount of hydration energy, which is easily displaced by the pores and cracks adsorbed on the metal surface and replaces the oxygen in the chloride layer, turning insoluble oxides into soluble chlorides and making the passivated surface active surface. Cause a very bad adverse reaction to the product.
