摘要： 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.
摘要翻译： 该方法包括将粉末放置在电隔离模具中，对粉末施加100-500MPa的压力，并在烧结时间期间将烧结电流施加到粉末上以烧结粉末。 在施加烧结电流密度之前，在低于烧结时间的活化时间期间，在大于烧结电压的活化电压下施加比烧结电流密度低的活化电流密度，以降低粉末的电阻。
