Galvanic Corrosion is an accelerated form of corrosion that occurs when two dissimilar metals are in an electrical contact. The more noble metal drives the corrosion of the active metal and this can be a very fast process. For example if an aluminum frame is connected with steel bolts then aluminum rapidly corrodes and after a few months the whole construction may collapse. So how to prevent galvanic corrosion? First, one should connect only those materials that have a similar electrochemical activity. Second, dielectric corrosion resistant coatings should be applied on the metal parts so that the electrochemical processes cannot take place.
This free educational video about galvanic corrosion was done in collaboration with the Institute of Physics, University of Tartu.
