Abstract
A flowable slurry comprising powder matrix particles and reinforcing particles is pumped, under pressure, through an atomizing nozzle to form discrete droplets containing reinforcing particles coated with the powder matrix particles The discrete droplets are suspended in an elevated temperature environment for a sufficient time to evaporate the water from the droplets and form nonreacted reinforced powder particles. The reinforced powder particles are nonagglomerated and are suitable for immediate use as powder for thermal spray coatings or for dry processed compacted structural components.
