What are the causes and countermeasures of galvanic corrosion? | Effective methods to prevent dissimilar metal corrosion.
As the "foundation of measures against electrolysis," we will briefly explain "why electrolysis occurs" and "what effective countermeasures are."
"When stainless steel pipes were used with carbon steel bolts, only the bolts rusted excessively. In the case of dissimilar metal connections in seawater piping, one of the metals became severely corroded." Do you have any experience with such "abnormal corrosion" of metals? It may not just be rust, but rather "galvanic corrosion." Galvanic corrosion progresses locally through a mechanism different from normal corrosion, and if left unchecked, it can lead to leaks from the piping, a decrease in equipment strength, and in the worst case, serious accidents. *For more details on the column, please refer to the related link.
