Abstract

A method of making a composite material in which a porous preform is produced by spray casting. An appropriate metal or alloy is caused to infiltrate the interconnected pores. This may be accomplished by infiltrating the porous preform with a liquid metal of a melting point lower than the melting point of the porous preform and thereafter solidifying the infiltrated material or the material can be infiltrated by the use of a slurry containing the desired particles and the liquid carrier driven off by baking the infiltrated preform. Alternatively, infiltration may be accomplished by plating of a desired metal or alloy from an appropriate infiltrate electroplating or electro-less plating solution.
