Abstract (en)
[origin: EP3208015A1] The method comprises placing the powders in an electrically isolating mold, applying a pressure to the powders between 100 and 500MPa and applying to the powders a sintering current at a sintering voltage during a sintering time, for sintering the powders. Before applying the sintering current density, applying an activation current density lower than the sintering current density at an activation voltage greater than the sintering voltage during an activation time lower than the sintering time, to reduce the electrical resistance of the powders.
