  • Patent number: 4863810
    Abstract: A method of providing corrosion resistant substrates having an amorphous metallic alloy coating thereon. The method comprises depositing refractory and transition elements, such as Ni, Nb, Ti and Cr, onto the substrate to provide a crystalline metallic layer thereon which is then irradiated to convert the layer into an amorphous metallic coating on the substrate. The coated substrate displays a corrosion resistance which is at least about four orders of magnitude greater than for the uncoated substrate in both lN HNO.sub.3 and 0.1 N NaCl aqueous solutions.
