Abstract
Przedmiotem wynalazku jest sposób otrzymywania półwyrobów z cyrkonu poprzez spiekanie iskrowo-plazmowe proszku cyrkonu, co w praktyce oznacza zastosowanie technologii SPS (ang. Spark Plasma Sintering). Wyroby z cyrkonu, jako innowacyjne produkty, mają zastosowanie w wielu dziedzinach, m.in. związanych: z energetyką jądrową, produkcją aparatury chemicznej oraz elementów urządzeń elektrycznych i elektronicznych, a także w dziedzinie chirurgii. W procesie spiekania iskrowo-plazmowego, z wykorzystaniem znanego urządzenia, przy zastosowaniu metody SPS, w próżni o wartości 0,01 - 0,10 mbar, korzystnie 0,05 mbar, proszek cyrkonu poddaje się w kolejnych zabiegach: prasowaniu pod ciśnieniem 50 - 100 MPa, korzystnie 80 MPa, utrzymując to ciśnienie przez cały czas trwania procesu, dalej nagrzewaniu z wykorzystaniem prądu impulsowego do temperatury spiekania 700 - 850°C, korzystnie 800°C, z szybkością nagrzewania 50 - 400°C/min, korzystnie 100°C/min, a następnie spiekaniu w temperaturze spiekania w czasie 5 - 15 min, korzystnie 10 min, oraz chłodzeniu do temperatury otoczenia z szybkością chłodzenia 5 - 400°C/min, korzystnie 10°C/min, po czym przeprowadza się operację wyżarzania ukształtowanego półwyrobu z cyrkonu w temperaturze 580 - 750°C, korzystnie 580°C, w czasie 30 - 120 min, korzystnie 120 min, i powoli chłodzi się półwyrób do temperatury otoczenia.The subject of the invention is a method of obtaining zirconium semi-finished products by spark-plasma sintering of zirconium powder, which in practice means the use of the SPS (Spark Plasma Sintering) technology. Zirconium products, as innovative products, are used in many areas, including related to: nuclear energy, production of chemical apparatus and elements of electrical and electronic devices, as well as in the field of surgery. In the spark-plasma sintering process, using a known device, using the SPS method, in a vacuum of 0.01 - 0.10 mbar, preferably 0.05 mbar, the zirconium powder is subjected to the following steps: pressing under a pressure of 50 - 100 MPa, preferably 80 MPa, maintaining this pressure throughout the process, further heating by impulse current to a sintering temperature of 700-850 ° C, preferably 800 ° C, at a heating rate of 50-400 ° C / min, preferably 100 ° C / min, followed by sintering at a sintering temperature of 5 - 15 min, preferably 10 min, and cooling to ambient temperature with a cooling rate of 5 - 400 ° C / min, preferably 10 ° C / min, followed by a shaped annealing operation the zirconium blank at a temperature of 580 - 750 ° C, preferably 580 ° C, for 30 - 120 min, preferably 120 min, and the blank is slowly cooled to ambient temperature.
