Abstract
Przedmiotem wynalazku jest sposób wytwarzania porowatych spieków majacych zastosowanie w chirurgii kostnej lub ukladach filtrujacych. Sposób wytwarzania porowatych spieków, polega na tym, ze proszek metalowy lub ceramiczny, lub mieszanina proszków metalowo-ceramicznych mieszany jest z krysztalami sacharozy, korzystnie cukru spozywczego o wielkosci krysztalów sacharozy 1-1,5 mm, korzystnie 1 mm w proporcji wagowej 1:1 oraz z dodatkiem 2-3 kropel alkoholu etylowego na 10 g mieszaniny, nastepnie mieszanina prasowana jest pod cisnieniem 500-700 MPa, po czym otrzymana wypraske umieszcza sie w poruszanej mieszadlem magnetycznym wodzie destylowanej o temperaturze 50-80°C, w czasie 1-2 h. Nastepnie wypraske suszy w temperaturze 60-80°C, dalej nagrzewa sie w ciagu 1 h od temperatury pokojowej do temperatury spiekania wlasciwej dla danego materialu w zakresie 1250-1300°C, przetrzymuje w tej temperaturze przez 1 h w atmosferze ochronnej, korzystnie w argonie, nastepnie spieki schladza sie w ciagu 1 h do temperatury pokojowej.The present invention relates to a method for the production of porous sinters for use in bone surgery or filtration systems. The method for producing porous sinters is that the metal or ceramic powder or metal-ceramic powder mixture is mixed with sucrose crystals, preferably food sugar with a size of 1-1.5 mm, preferably 1 mm, 1: 1 weight ratio and with the addition of 2-3 drops of ethyl alcohol per 10 g of the mixture, then the mixture is pressed under 500-700 MPa pressure, after which the obtained compact is placed in distilled water moved with a magnetic stirrer at a temperature of 50-80 ° C, during 1-2 h. The compact is then dried at 60-80 ° C, further heated within 1 hour from room temperature to the sintering temperature appropriate for the given material in the range 1250-1300 ° C, kept at this temperature for 1 hour in a protective atmosphere, preferably at argon, then the sintered is cooled to room temperature within 1 hour.
