Abstract
Przedmiotem wynalazku jest sposób wytwarzania porowatych spieków tytanowych (na bazie tytanu, stopów tytanu i kompozytów na osnowie tytanowej) za pomocą procesu termicznego odstępowania magnezu. Sposób wytwarzania porowatych spieków tytanowych, ze stopów tytanu lub kompozytów na osnowie tytanowej w procesie odstopowania magnezu charakteryzuje się tym, że proszki tytanu i magnezu i ewentualnych innych dodatków stopowych (Ta, Nb, Zr, Mo, Si, Fe, AL, V), w proporcjach uwzględniających gęstość lub objętość 30 - 70 mas.%, korzystnie 50 mas.%, poddaje się procesowi mechanicznej syntezy w atmosferze ochronnej argonu z kontrolowaną zawartością tlenu i wody na poziomie ? 1 ppm, przy stosunku masy mielników do masy proszku minimum 10, korzystnie 20, w czasie 8 - 10 godzin, korzystnie przez 10 godzin, następnie stop w postaci proszku prasowany jest pod ciśnieniem 500 - 1000 MPa, korzystnie 1000 MPa, następnie wypraski poddawane są spiekaniu z jednoczesnym procesem odstopowania w temperaturze powyżej temperatury wrzenia magnezu, 1200 - 1300°C, korzystnie 1300°C, w ciągu 1 - 5 godzin, korzystnie 2 godzin, w próżni; następnie spieki studzi się z piecem.The subject of the invention is a method of producing porous titanium sinters (based on titanium, titanium alloys and titanium matrix composites) by means of a thermal magnesium deposition process. The method of producing porous titanium sinters from titanium alloys or titanium matrix composites in the process of magnesium alloying is characterized by the fact that titanium and magnesium powders and any other alloying additives (Ta, Nb, Zr, Mo, Si, Fe, AL, V), in proportions that take into account the density or volume of 30-70 mass%, preferably 50 mass%, are subjected to a mechanical synthesis process in a protective atmosphere of argon with controlled oxygen and water content at the level of 1 ppm, with a mass ratio of grinders to powder mass of a minimum of 10, preferably 20, in 8-10 hours, preferably for 10 hours, then the alloy in the form of powder is pressed at a pressure of 500 - 1000 MPa, preferably 1000 MPa, then the compacts are subjected to sintering with a simultaneous melting process at a temperature above the boiling point of magnesium, 1200-1300 ° C, preferably 1300 ° C, for 1-5 hours, preferably 2 hours, in a vacuum; then the sinter is cooled with the furnace.
