Device with a large-current electronic connector for the consolidation of powder materials and the method for consolidation of powder material using the apparatus with a large-current electronic connector

摘要

The object of the invention is a device for the consolidation of powder materials, equipped with a working chamber,Pressure combined with high-current (upper and lower) discharge electrodes (electrically isolated from the process chamber and moving vacuum vents),between which is a consolidated powder which is under pressure from the press. The upper and lower electrodes are connected by a capacity circuit with a power supply closed by a high-current connector, which is a transistor key. The invention is also a way of consolidating the powder materials in the device according to the invention, The powder is simultaneously subjected to 1-200 MPa pressure and to the consolidation by 1-80 kA electric current pulses, repeated at a frequency ranging from 0,1 Hz to 100 Hz, caused by opening and closing the transistor key.
