Title: Steel bonded dense silicon nitride compositions and method for their fabrication

Abstract

A method of fabricating a multilayered ceramic-metal composite is described comprising: (a) polishing a surface of a dense ceramic material to enhance wetting and reaction with molten reactive material; (b) applying a thin slurry coating of a fine powder mixture of a refractory material comprising a mixture of powdered nickel and molybdenum silicide and bonding it to the surface of the ceramic material; (c) grinding the layer of refractory material to uniform thickness; (d) brazing a surface of the layer of refractory material with a metal alloy at elevated temperatures; and (e) pressure bonding a metal piece to the metal alloy to form the composite.
