Optical microscopic examination was performed on all tested specimens to evaluate the extent of surface damage resulting from galvanic interaction. Galvanic corrosion (also called bimetallic corrosion or dissimilar metal corrosion) is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another, in the presence of an electrolyte. A similar galvanic reaction is exploited in primary cells to generate a useful electrical voltage to power portable devices. This phenomenon is named after Italian physician Luigi Galvani (1737-1798). chinese song tomorrow will be better https://gfreemanart.com
