<p>A metal, e.g. in the form of a shaped article, is made by atomizing a stream of molten metal and directing the atomized stream at a collecting surface to form a deposit of the metal. Fine, solid particulate material of different composition from the metal, e.g., nonmetallic particles, and of mean particle size less than 20 micrometers, preferably less than 10 micrometers, is applied to the stream or spray so that it becomes incorporated into the deposit. The particulate material is applied by generating a fluidized bed thereof and feeding it from the bed into the stream or spray. Uniform dispersion of material such as SiC at a high volume percentage (e.g. greater than 15%) may be achieved.</p> |
