Abstract
A device for producing metallic particles utilizing the Coanda Effect to draw one stream of gas toward another stream of gas flowing over a foil. Molten metal is introduced between the two gas streams, and the resulting interaction breaks up the molten metal flow into particles of appropriate size, shape, composition and the like. Various embodiments can be used for the process of producing cast articles, while other versions can be used for the process of coating and deposition of the particles in liquid, solid or partially solidified form onto a substrate.
Claims18
A device for producing a metallic particle comprising:
- means defining a Coanda surface;
- means for flowing a first fluid along said Coanda surface;
- a second fluid located adjacent said Coanda surface to be influenced by the flow of said first fluid toward an intersection with said first fluid;
- means for introducing a flow of molten metal between said first and second fluids to permit entrainment and associated breakup of said molten metal into metallic droplets;
- and
- means for receiving said metallic droplets on a substrate which forms the metallic droplets into a coated or molded article.
Apparatus for producing metallic articles comprising:
- means for producing a Coanda Effect;
- means for providing a source of molten metal to be entrained in said Coanda Effect;
- and
- means for receiving metal droplets as produced by the aforesaid structure which forms the metallic droplets into a coated or molded article.
