Ƙirƙirar tana da alaƙa da fannin ƙarfe na foda da kuma samar da na'urori masu ƙarfi da aka yi amfani da su a kan tungsten carbide, waɗanda za a iya amfani da su don kera na'urori, na'urori, niƙa da sauran kayan aikin.
Sanin sintered carbide dangane da tungsten carbide, dauke da 3.0 zuwa 20.0 wt.% A binder gami dauke, wt.%: Cobalt 20.0-75.0;molybdenum - har zuwa 5.0;niobium - har zuwa 3.0 [1].
Manufar ƙirƙirar ita ce ƙara ƙarfin gami.
Ana samun sakamakon fasaha a cikin abin da aka yi amfani da shi a cikin wani nau'i mai mahimmanci wanda ya dogara da tungsten carbide dauke da 80.0-82.0 wt.% Tungsten carbide da 18.0-20.0 wt.% Binder, mai ɗaure ya ƙunshi, wt.%: Molybdenum 48 0-50.0;niobium 1.0-2.0, rhenium 10.0-12.0;cobalt 36.0-41.0.
A cikin tebur.1 yana nuna abun da ke ciki na gami, da kuma ƙarfin ƙarshe a cikin lanƙwasa.A cikin tebur.2 yana nuna haɗin haɗin gwiwa.
Tebur 1 Abubuwan Haɗawa, wt.%: ɗaya 2 3 Wolfram carbide 80.0 81.0 82.0 Bunch 20,0 19.0 18.0 Ƙarfin Lankwasawa, MPa ~ 1950 ~ 1950 ~ 1950
Tebur 2. Abubuwan Haɗaɗɗiya, wt.%: ɗaya 2 3 Molybdenum 48.0 49.0 50,0 Niobium 1,0 1,5 2.0 Rhenium 10.0 11.0 12.0 Cobalt 41.0 38.5 36.0
Ana haɗe foda na kayan haɗin gwal a cikin adadin da aka nuna, ana matse cakuda a ƙarƙashin matsin lamba na 4.5-4.8 t / cm 2 kuma an sanya shi a cikin tanderun lantarki a zazzabi na 1300-1330 ° C a cikin injin don awanni 7-9.Lokacin sintering, mai ɗaure yana narkar da wani ɓangare na tungsten carbide kuma ya narke.Sakamakon abu ne mai yawa wanda tsarinsa ya ƙunshi barbashi na tungsten carbide da aka haɗa ta hanyar ɗaure.
