Quality engineering and design requires an understanding of material compatibility. Galvanic corrosion (some times called dissimilar metal corrosion) is the process by which the materials in contact with each other oxidizes or corrodes. There are three c

In a galvanic couple, the higher resistance metal turns cathodic while the less resistant one becomes anodic. Typically, the cathodic material undergoes little or no corrosion at all in a galvanic couple. Due to the unlike metals that are involved and the electric currents, the type of corrosion...
Galvanic-induced failure is corrosion damage or failure induced by galvanic coupling. This is an aggressive and localized form of corrosion due to electrochemical reactions often found between two or more dissimilar metals in an electrically conductive environment. It is usually associated with black ste...
Galvanic cells are also important for corrosion protection. Any two metals can be used to make a galvanic cell. If two metals are in contact, one metal can be the anode and the other the cathode, leading to galvanic corrosion of the more anodic metal. Two metals having different potentials...
