A slurry for joining metallic or ceramic surfaces or for coating metallic or ceramic and refractory surfaces, comprising a liquid suspending medium and at least two constituents in particulate form suspended in the medium, the constituents being so selected and proportioned as to undergo combustion synthesis when ignited. A method for coating or joining metallic or ceramic surfaces comprises applying such a slurry to a surface to be coated or to surfaces to be joined, and igniting the slurry to cause combustion synthesis.

Combustible slurry for joining metallic or ceramic surfaces or for

The present invention relates to a method of making metal ceramic composites and the metal ceramic compositions and articles made therefrom, especially net-shaped articles having a wide variety of applications. The present invention involves preparing a combustion synthesis mixture comprising at least one substance containing a combustible mixture of powders and at least one low-melting metal, forming this mixture into a desired final shape in a die, and carrying out a combustion synthesis therewith. Ceramic or metallic reinforcements may be incorporated in the combustion synthesis. The present invention allows the control of porosity in the resultant composite compositions and can result in composites having high toughness characteristics.
