Abstract
A powder consolidation method and apparatus make use of corrosion processes occurring on surfaces of metal particles to consolidate a metal-containing powder into a formed body. The method includes contacting metal particles with an acidic or basic liquid at a pH and potential at which dissolution of metal from the particles and reduction of soluble metal-containing ions to metal on surfaces of the particles can co-occur, such that the metal powder agglomerates to form a body.
