What is Galvanic Corrosion and How Can it be Prevented
Galvanic corrosion can be prevented by Selecting materials with similar corrosion potentials. Breaking the electrical connection by insulating the two metals from each other. Applying coatings to both materials. The coating on the cathode is the most important and must be in good condition otherwise the galvanic corrosion could be worsened.
