A single pulse of 0.75-2.0 kJ/0.7 g atomized spherical Ti-6Al-4V powder using 150, 300 and 450 μF capacitors was applied in an Ar atmosphere. After discharge, the self-assembled solid core surrounded by a porous layer was composed of Widmanstätten α + β grains. By manipulating the discharge conditions such as input energy and capacitance, including powder size, porous-surfaced Ti-6Al-4V implant-typed compacts with various porosities can be produced in short times less than 200 μs without changing the unique microstructure.
