Corrosion is the reason which lead to the damage or deterioration of material or its performance under the action of the environment. Most of corrosion happen in environment. Salt spray corrosion is a common and most damaging atmospheric corrosion. The corrosion of salt fog on the surface of metal materials is caused by the electrochemical reaction of the oxide layer and protective layer of the chloride ion penetrating the metal surface and the internal metal. At the same time, chlorine ion can contain certain hydration, easy to be adsorbed on the surface of the metal, porosity, crack out and replace the oxygen oxidation layer, insoluble oxide into soluble chloride, make surface passivization to state active surface. To cause a bad reaction to the product.Salt spray chamber price is used not to predict the corrosion resistance of a coating, but to maintain coating processes such as pre-treatment and painting, electroplating, galvanizing, and the like, on a comparative basis. Our salt spray corrosion test chamber meets with ASTM B117 salt spray standard and Other important relevant standards ISO9227, JIS Z 2371 and ASTM G85.
