Steel-Based Sprayed Metal Tooling

A strategy for building sprayed steel tooling by arc spray deposition is discussed in this paper. Depositing steel is crucial for moving sprayed metal toolingfrom prototype applications to superior prototype and production-quality tooling. Tooling is fabricated by spraying onto S\lbStra~S that define the tooling shell shape. In particular, two process issues are addressed: deposition of thick metal shells, and control of oxide content by atomization with inert gases.
