Title:
A DEVICE AND A METHOD FOR CONSOLIDATION OF POWDER MATERIALS
Document Type and Number:
WIPO Patent Application WO/2014/155352
Kind Code:
A3
Abstract:
The object of the invention is a device intended for powder materials consolidation, provided with an operating chamber, press connected to high-current discharge electrodes top and bottom, with arranged therebetween the sintered powder subjected to the pressure exerted by the press. To the top and bottom electrode there is connected a capacitive circuit with a power supply unit, closed by a high-current switch being a transistor switch. The object of the invention is also a method of powder materials consolidation in the device according to the invention, wherein the powder material is subjected to simultaneous operation of pressure in the range of 1-200 MPa and consolidation by electric current pulses with intensity of 1-80 kA, repeated with frequency from the range of 0.1 Hz to 100 Hz, generated by opening and closing the transistor switch.
