Term explanation: What is intergranular corrosion? Intergranular corrosion is a type of selective corrosion that occurs at the grain boundaries of metals or alloys, without significant erosion of the grains or crystals themselves. ============================== Event Promotion: Petrochemical Zone – “Creative Ideas for Energy Savings” event (the second phase is in full swing) http://bbs.hcbbs.com/thread-1666758-1-1.html (Source: Haichuan Chemical Industry Forum) 2017 Coal Chemical Industry Event – “My Technical Upgrades” http://bbs.hcbbs.com/thread-1786290-1-1.html (Source: Haichuan Chemical Industry Forum)
A type of local corrosion that occurs in metal materials within specific corrosive environments, along the grain boundaries of the material.
Corrosion that spreads inward along the boundaries between metal grains
Intergranular corrosion is a common type of localized corrosion. Corrosion occurs along the grain boundaries of a metal or alloy or in the areas adjacent to them; since the grains themselves are only slightly corroded, this type of corrosion is known as intergranular corrosion.
Intergranular corrosion is a type of local corrosion. Corrosion that spreads inward along the boundaries between metal grains. This is mainly due to the differences in chemical composition between the grain surface and the interior, as well as the presence of impurities at grain boundaries or internal stresses.
