Filed:

Jun 21, 2002

Appl. No.:

10/177540

Inventors:

David Senor - West Richland WA, US
Roger Johnson - Richland WA, US
Bruce Reid - Pasco WA, US
Edward Love - West Richland WA, US
Sandra Larson - Richland WA, US
Andrew Prichard - Richland WA, US

International Classification:

B23K028/00

US Classification:

219/076130

Abstract:

A laminated structure having two or more layers, wherein at least one layer is a metal substrate and at least one other layer is a coating comprising at least one rare earth element. For structures having more than two layers, the coating and metal substrate layers alternate. In one embodiment of the invention, the structure is a two-layer laminate having a rare earth coating electrospark deposited onto a metal substrate. In another embodiment of the invention, the structure is a three-layer laminate having the rare earth coating electrospark deposited onto a first metal substrate and the coating subsequently bonded to a second metal substrate. The bonding of the coating to the second metal substrate may be accomplished by hot pressing, hot rolling, high deformation rate processing, or combinations thereof. The laminated structure may be used in nuclear components where reactivity control or neutron absorption is desired and in non-nuclear applications such as magnetic and superconducting films.
