Detection Purpose: To test the resistance of aluminum alloy to intercrystalline corrosion
Detection range: 2 series, 5 series, 7 series and other aluminum alloy and aluminum alloy products
Intercrystalline corrosion test:
Intergranular corrosion is a common local corrosion of metal corrosion, corrosion from the surface of the metal, along the grain boundary to the internal development of the grain, making the adhesion between the grains greatly weakened, reducing the strength of the material, serious can make the material's mechanical strength completely lost, it is one of the forms of local corrosion with great harm. There is no obvious change in the appearance of materials after intergranular corrosion, but the strength has been completely lost, which will cause sudden damage to the equipment. Therefore, it is of great significance for the national economic construction to study the mechanism of intergranular corrosion and take effective protective measures.
