FILIN: aikin ƙarfe.
ABUBUWAN DA KE CIKI: Ƙirƙirar ta shafi filin ƙarfe na foda. Musamman ma tana da alaƙa da karɓar ƙarfe mai tauri da aka yi da sintered a kan tungsten carbide. Ana iya amfani da ita don kera masu yankewa, injinan haƙa da kuma injin niƙa. Gilashin ƙarfe mai tauri ya ƙunshi 80.0-82.0% na tungsten carbide da 18.0-20.0% na ɗaurewa. Gilashin ƙarfe ya ƙunshi, wt%: molybdenum 48.0-50.0; niobium 1.0-2.0; rhenium 10.0-12.0; cobalt 36.0-41.0.
SAKAMAKON: karɓar ƙarfe mai ƙarfi.

Wannan ƙirƙira ta shafi fannin ƙarfe na foda da kuma samar da ƙarfe masu tauri da aka yi da sintered bisa ga tungsten carbide, wanda za a iya amfani da shi wajen ƙera kayan yanka, injinan haƙa, injin niƙa da sauran kayan aiki.
Sanannen carbide mai sintered wanda aka gina shi da tungsten carbide, wanda ke ɗauke da 3.0 zuwa 20.0 wt.% A gami mai ɗaurewa wanda ke ɗauke da, wt.%: Cobalt 20.0-75.0; molybdenum - har zuwa 5.0; niobium - har zuwa 3.0 [1].
Manufar ƙirƙirar wannan ƙirƙira ita ce ƙara ƙarfin ƙarfen.
An cimma sakamakon fasaha ta hanyar cewa a cikin wani ƙarfe mai tauri da aka yi da sintered wanda aka gina a kan tungsten carbide wanda ke ɗauke 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 cikin kayan haɗin, da kuma ƙarfin da ke cikin lanƙwasa. A cikin tebur. 2 yana nuna abun da ke cikin jijiyar.
Tebur 1 Abubuwan da aka haɗa, kashi ɗaya bisa uku: ɗaya 2 3 Wolfram carbide 80.0 81.0 82.0 Bunch 20,0 19.0 18.0 Ƙarfin lanƙwasa, MPa ~ 1950 ~ 1950 ~ 1950
