How can Galvanic Corrosion be Prevented?
Open in App
Solution
- To block the passage of electrons between the two metals and avoid galvanic coupling, electrical insulation is positioned between them.
- Using a galvanic isolator, which can be two parallel series semiconductor diodes with two diodes conducting in the opposite way.
- Galvanic corrosion can be avoided by using an impermeable covering on the metal surface, such as paint, to ensure that the metal won't come into touch with an electrolyte.
- The quantity of galvanic current that will pass through metals when used together is reduced. As a result, the metal's rate of galvanic corrosion is decreased.
- Galvanic corrosion of the metal can also be decreased by electroplating it with a thin coating of inert metal.
