Bulk metallic glasses show excellent surface properties such as high resistance to corrosion, erosion, and wear. These characteristics are simplistically attributed to their uniform amorphous structure with no grain boundaries, high hardness, and chemical inertness. However, the intricacies of the mechanisms are often ignored and are of paramount importance to fundamentally understand amorphous alloys. For example, the corrosion behavior may change dramatically with slight change in chemistry even though the amorphous structure is maintained. There are similar reports on wear behavior. We compared the surface properties of several BMGs with processing conditions ranging from surface rejuvenation to thermal relaxation. This provided valuable insights into the role of chemistry, free volume, and surface state on the degradation behavior of BMGs.
