Self-propagating High-temperature Synthesis (SHS) is a novel, economical, method of producing intermetallic composite powders. These materials have potential applications in high temperature engine components and burner nozzles, enabling higher operating temperatures and fuel efficiencies to be achieved. SHS MoSi{sub 2}/SiC composites with up to 30 v/o of the SiC reinforcing phase have been produced and successfully consolidated by low pressure plasma spray. Microstructural characterization of the powders and sprayed coatings, and measurements of mechanical properties (fracture toughness etc.) indicate that plasma sprayed SHS materials exhibit properties superior to those of conventionally produced MoSi{sub 2} materials.
