Summary

The new technique spray forming also known as spray casting or Osprey-process fills the gap between casting and powder metallurgy and offers economic benefits compared to both. In spray forming a molten metal stream is atomized into micron-size droplets by gas jets, directing the droplets towards a substrate. Depending on size the impacting droplets arrive at the substrate in either a fully solid, fully liquid or mushy state and form a thin semisolid layer which solidifies incrementally.
