Intergranular corrosion test
 
Intergranular corrosion is a type of local corrosion, namely the corrosion extending to the inside along the boundary between metal grains.
 
Intergranular corrosion test is a fast metal corrosion test that tests the intergranular corrosion susceptibility of metallic material under specific media conditions. It is to understand whether the chemical composition, heat treatment and processing of the material are reasonable. The principle is to use a variety of test solutions that allow the corrosion potential of the metal to be within a specific interval of the anodic polarization curve of constant potential. The significant difference in the corrosion current between the metal grain and the grain boundary in this potential interval is used to accelerate the display of intergranular corrosion.
