NISKAYUNA, N.Y., Nov 07, 2013 -- A potential "fountain of youth" for metal, GE researchers announced the use of a process called "cold spray," in which metal powders are sprayed at high velocities to build a part or add material to repair an existing part. Cold spray is part of GE's expanded additive manufacturing toolkit. Anteneh Kebbede, Manager of the Coating and Surface Technologies Lab at the GE Research Center said, "In addition to being able to build new parts without welding or machining, what's particularly exciting about cold spray coatings as an innovative, 3D process is that it affords us t
