Insimbi ye-Tungsten: Umkhiqizo oqediwe uqukethe cishe i-18% yensimbi ye-tungsten alloy. Insimbi ye-Tungsten ingeye-hard alloy, eyaziwa nangokuthi i-tungsten-titanium alloy. Ukuqina yi-10K Vickers, okwesibili ngemuva kwedayimane. Ngenxa yalokhu, imikhiqizo yensimbi ye-tungsten (amawashi ensimbi e-tungsten avamile) inesici sokungagqoki kalula. Isetshenziswa kaningi kumathuluzi e-lathe, ama-drill drill bits, ama-glass cutter bits, ama-tile cutters. Inamandla futhi ayikwesabi ukuhushulwa, kodwa iyaphuka.
I-carbide enosimende: ingeyomkhakha we-powder metallurgy. I-carbide enosimende, eyaziwa nangokuthi i-ceramic yensimbi, iyi-ceramic enezici ezithile zensimbi, eyenziwe nge-carbides yensimbi (WC, TaC, TiC, NbC, njll.) noma ama-oxide ensimbi (afana ne-Al2O3, ZrO2, njll.) njengezingxenye eziyinhloko, kanye nenani elifanele le-powder yensimbi (Co, Cr, Mo, Ni, Fe ngokusebenzisa i-powder metallurgy). I-Cobalt (Co) isetshenziselwa ukudlala umphumela wokuhlanganisa ku-alloy, okungukuthi, ngesikhathi senqubo ye-sintering, ingazungeza i-tungsten carbide (WC) powder futhi ihlanganiswe ngokuqinile ndawonye. Ngemuva kokupholisa, iba yi-carbide enosimende. (Umphumela ulingana nosimende kukhonki). Okuqukethwe ngokuvamile: 3% -30%. I-Tungsten carbide (WC) iyingxenye eyinhloko enquma ezinye izakhiwo zensimbi zale carbide enosimende noma i-cermet, ibalwa ku-70% -97% wesamba sezingxenye (isilinganiso sesisindo). Isetshenziswa kabanzi ezingxenyeni ezingagugi, ezimelana nokushisa okuphezulu, ezingxenyeni ezimelana nokugqwala noma imibese namakhanda amathuluzi ezindaweni zokusebenza ezinokhahlo.
Insimbi ye-Tungsten ingeye-carbide enosimende, kodwa i-carbide enosimende ayiyona insimbi ye-tungsten. Namuhla, amakhasimende ase-Taiwan nasemazweni aseNingizimu-mpumalanga ye-Asia athanda ukusebenzisa igama elithi tungsten steel. Uma ukhuluma nabo ngokuningiliziwe, uzothola ukuthi iningi labo lisabhekisela ku-carbide enosimende.
Umehluko phakathi kwensimbi ye-tungsten ne-cemented carbide ukuthi insimbi ye-tungsten, eyaziwa nangokuthi insimbi enesivinini esikhulu noma insimbi yamathuluzi, yenziwa ngokwengeza insimbi ye-tungsten njengempahla eluhlaza ye-tungsten ensimbi encibilikisiwe kusetshenziswa ubuchwepheshe bokwenza insimbi, eyaziwa nangokuthi insimbi enesivinini esikhulu noma insimbi yamathuluzi, futhi okuqukethwe kwayo kwe-tungsten kuvame ukuba ngu-15-25%; kuyilapho i-carbide enosimende yenziwa nge-sintering tungsten carbide njengomzimba oyinhloko one-cobalt noma ezinye izinsimbi ezibophayo zisebenzisa ubuchwepheshe be-powder metallurgy, futhi okuqukethwe kwayo kwe-tungsten kuvame ukuba ngaphezu kwama-80%. Kalula nje, noma yini enobulukhuni obudlula i-HRC65 inqobo nje uma iyingxubevange ingabizwa nge-cemented carbide, futhi insimbi ye-tungsten iwuhlobo nje lwe-carbide enosimende enobulukhuni obuphakathi kwe-HRC85 nama-92, futhi ivame ukusetshenziselwa ukwenza imimese.
