<p>A system for the spray forming manufacturing of near-net-shape molds, dies a nd related toolings, wherein liquid material such as molten metal, metallic alloys, or polymers are atomized into fine droplets by a high temperature, high velocity gas and deposited onto a pattern (34). Quenching of the in- flight atomized droplets by a quench gas in a chamber (51) provides a heat sink, thereby allowing undercooled and partially solidified droplets to be formed in-flight. Composites can be formed by combining the atomized droplet s with solid particles such as powders, whiskers or fibers.</p> |
