We will provide a detailed introduction to general corrosion, pitting corrosion, and galvanic corrosion!
The main forms of corrosion include "uniform corrosion, pitting corrosion, and galvanic corrosion." Other types of corrosion include "crevice corrosion," which occurs due to the formation of an oxygen concentration cell in tiny gaps on the order of microns, "grain boundary corrosion," where the grain boundaries preferentially corrode, "erosion corrosion," which involves the action of wear by fluids, and "high-temperature oxidation," which occurs in high-temperature atmospheres or steam. Our technical information site "Screw Fastening Technology Navi," which contributes to solving issues related to screw fastening, features the three main forms of corrosion (uniform corrosion, pitting corrosion, and galvanic corrosion). Please take a look through the related links.
