Raws li peb txhua tus paub, cemented carbide muaj cov khoom ruaj khov thiab yog siv dav hauv kev ua tub rog, machining, metallurgy thiab yog hu ua "hniav hniav". Nyob rau hauv xyoo tsis ntev los no, nrog kev txhim kho riam phom siab thiab khoom siv thiab kev ua lag luam nrawm rau lub zog ua kom zoo ntawm carbide tau maj mam nthuav dav.
Raws li rau cov cemented carbide, coob leej ntau tus tsis quav ntsej nws. Coob tus neeg paub tungsten carbide thiab tungsten steel, tab sis lawv tsis paub qhov kev sib txuas thiab qhov sib txawv ntawm ob.
Cemented carbide kuj tseem hu ua lub harding compound alloy cov khoom siv sib xyaw ua ke, thiab muaj peev xwm ua tau zoo ntawm cov hmoov av, thiab muaj peev xwm ua tau zoo ntawm cov hmoov av uas muaj zog, thiab muaj peev xwm ua tau zoo ntawm kev siv hluav taws xob ntau ntawm 1000 ° C, nws tseem muaj a Hardness uas lwm yam hlau tsis tuaj yeem ua tiav.
Tungsten carbide yog lub ntsiab tivthaiv yog lub ntsiab lus carbide, ntawm cov ntsiab lus sib xyaw ua ke, cov ntsiab lus tsuas yog siv cov nyiaj siv rau carbide, thiab tom qab txias txias, muaj cov cemented carbide peb pom. Kev txiav ceev ntawm cov cuab yeej ua los ntawm carbide no yog 15 lub sij hawm nrawm dua li 3 lab ntau dua li 3 lab nyob rau hauv cov nroj tsuag tshuaj lom neeg, ntsuas hluav taws xob nrawm, thiab lwm yam.
Raws li cov muaj pes tsawg leeg thiab kev ua tiav cov yam ntxwv ntawm kev tso cai carbide, nws yog muab faib ua tungsten cibalt, tungsten tunanium tantalum (niobium). Hauv peb cov kev siv tswv yim, cov feem ntau cov uas yog tungsten cobalt thiab tungsten titanium cobalt cemented carbide. Raws li lub npe qhia, lub ntsiab Cheebtsam ntawm tungsten cemented carbide thiab cobalt, thaum lub sij hawm lub ntsiab lus carbide yog tungsten carbide, titanium carbide thiab cobalt.
Thiab peb tab tom tham txog tungsten steel kuj yog ib hom cemented carbide, uas yog sintered composite cov khoom siv ntawm tsawg kawg ib hlau carbide. Tungsten Steel belong belong belongs kom cemented carbide, yog li nws tseem hu ua "tungsten titanium alloy". Tungsten steel muaj lub hardness ntawm vickers 10k, thib ob tsuas yog pob zeb diamond, thiab tseem muaj lub zog muaj zog thiab tiv thaiv kev hnav, cua sov thiab xeb. Hauv lub neej, tungsten steel cutters, percussion laum, thiab tom qab ntawd, nws yog qhov ntsuas kub, yog li nws tau siv dav hauv tub rog thiab Muaj chaw teb.
Qhov sib txawv ntawm tungsten steel thiab cemented carbide yog feem ntau yog tungsten steel mus rau kev ntxiv cov khoom siv tungsten, thiab cov cuab yeej siv tunglaking ntau lossis cov tungsten cov ntsiab lus feem ntau 15-25%. Yog li no, txhua qhov alloys nrog Hardness Top HRC65 tuaj yeem hu ua tungsten carbide, thaum tungsten carbide tsis tas tungsten steel.
