The solid-state spray forming of low-oxide titanium components

This paper presents a novel approach for the production of essentially oxide-free Ti parts in near-net shapes. The hydride-dehydride (HDH) process is used to produce oxide-free titanium (OFTi) powder; the powder is then used as feedstock for the solid-state spray forming (SSF) process. Older spray forming techniques (e.g., thermal, Osprey, and low-pressure plasma spray) are not particualrly suited to the production of parts of near-net shape and typically introduce supplementary oxidation.
