Abstract
Przedmiotem zgłoszenia jest spiek o gęstości względnej powyżej 99% na osnowie cyrkonu, z dodatkiem 1 - 2,5% masy proszku manganu, o wielkości cząstek od 0,05 µm do 45 µm. Materiał jest otrzymywany bez stosowania procesów redukcji składników lub ich rozkładu termicznego. Materiał charakteryzuje się wysoką twardością i jest trudno obrabialny metodami obróbki ubytkowej. Sposób wytwarzania spieku polega na spiekaniu mieszanki proszków metali metodą prądu impulsowego SPS, w matrycy grafitowej z naniesioną warstwą heksagonalnego azotku boru, w temperaturze 1100 - 1200°C, w argonie, pod ciśnieniem 35 - 55 MPa, po czym spieczony materiał poddaje się chłodzeniu z szybkością równą lub niższą niż 50°/min.The subject of the application is a sinter with a relative density of more than 99% on a zirconium matrix, with the addition of 1 - 2.5% by weight of manganese powder, with a particle size from 0.05 µm to 45 µm. The material is obtained without the use of reduction or thermal decomposition processes. The material is characterized by high hardness and is difficult to machine by subtractive methods. The sinter production method consists in sintering a mixture of metal powders using the SPS pulse current method, in a graphite matrix with a layer of hexagonal boron nitride, at a temperature of 1100 - 1200 ° C, in argon, under a pressure of 35 - 55 MPa, after which the sintered material is cooled with at a speed equal to or less than 50 ° / min.
