Amorphous metals have generated much interest, both in basic research and for structural applications, because of their near-theoretical strength to stiffness ratio and extremely low damping characteristics. In addition, a number of amorphous metals exhibit excellent corrosion resistance, which has been explained in terms of their structural homogeneity. Since amorphous metals are in principle structurally and chemically homogeneous and thus lack any microstructure, such as grain boundaries, which could act as local electrochemically-active sites, many researchers attribute good corrosion resistance to the entire class of amorphous metals. It is this point, whether the amorphous condition itself confers improved corrosion resistance, that the authors examine in the present note.
