Abstract:

This invention relates to amorphous metal alloys and particularly to amorphous metal alloy coatings for protecting metals against corrosion. Metallic glasses are relatively new materials that are produced in the form of ribbons, wires, or coatings by rapid solidification from either the liquid or vapor state. They are truly noncrystalline alloys which combine the properties of a metal electrical conductivity, metallic luster, etc. with the lack of long range order typical of a glass. They are very homogeneous and lack the defects typical of a crystalline material, such as grain boundaries and dislocations.
