Ib yam li nyob rau hauv cov ntaub ntawv xaiv steel, xaiv qhov zoo tshaj plaws qib ntawm tungsten carbide (WC) yog cov txheej txheem nyuaj ntawm kev hnav uas muaj sia ntawm kev hnav khaub ncaws ntawm hnav-kev tiv thaiv thiab tawv / poob siab tsis kam. Cemented tungsten carbide yog ua los ntawm sintering (ntawm qhov kub ntawm tungsten carbide hmoov nrog cov hlau nplaum uas ua rau lub cev tsis tshua muaj zog ntawm lub cev. Cov tshav kub ntawm Sintering cov txheej txheem tsis koom nrog cov tshuaj tiv thaiv ntawm 2 lub xeev, tab sis nws ua rau encaptulating kua nplaum matrix rau WC cov lus (uas tsis muaj kev cuam tshuam los ntawm tshav kub). Ob qho tsis muaj, uas yog qhov sib piv ntawm cobalt rau WC thiab WC Particle qhov loj me ntawm qhov tshwm sim "cemented tungsten carbide" daim.
.
Qhia meej ib qho loj WC porticle loj thiab feem pua ntawm kev cob qhia yuav tawm los ua lub zog tsis txaus siab (thiab siab cuam tshuam lub zog) feem. Tus finer WC grain loj (yog li ntawd, ntau dua wc nto thaj tsam uas yuav tsum tau coated uas tau coated nrog cobalt nrog, qhov nyuaj thiab hnav ntau-resistant qhov tshwm sim yuav. Kom tau txais kev ua tau zoo tshaj plaws los ntawm carbide li cov hniav hniav, nws yog ib qho tseem ceeb kom tsis txhob muaj kev ua kom tsis taus thaum ntxov lossis tawg ua kom zoo tshaj plaws hnav tsis kam.
Raws li cov tswv yim ua tswv yim, kev tsim khoom tsis tshua muaj teeb meem, tsis tshua muaj siab heev ntawm cov npoo uas muaj cov tshuaj ntsuab zoo siv (txhawm rau tiv thaiv cov kab loj loj thiab cov npoo loj). Muab kev siv ntawm carbide uas muaj ib qho nruab nrab grain loj ntawm 1 micron lossis tsawg dua, carbide hniav kev ua tau zoo; Yog li ntawd, dhau los ua cov% ntawm kev cobalt thiab ntug geometry teev. Txiav cov ntawv thov uas muaj teeb meem rau cov high shocks loads yog qhov zoo tshaj plaws ntawm 12-15 feem pua cobaltry muaj ib qho chaw nyob sab ntawm txog 40º. Cov ntawv thov uas koom nrog cov kev sib zog sib zog thiab muab tus nqi tshaj plaws rau carbide uas muaj 6-9 feem pua cobalt thiab muaj ib qho chaw muaj huab cua nyob hauv thaj tsam ntawm 30-35º.
Tungsten carbide yog qhov ntev tshaj plaws hnav hniav hniav ntev tshaj plaws muaj rau ntau cov ntawv thov slitting. Peb tau pom nws hnav txog 75x ntev dua cov qauv steel tuaj. Yog tias koj xav tau tus hniav hnav ntev ntev, tungsten carbide feem ntau muab rau koj hnav-lub neej koj yuav tsum nce koj cov khoom lag luam.
Cov cuab yeej siv lub siab nyiam tsuas yog siv lub siab zoo tshaj plaws tungsten carbide kom paub tseeb tias peb cov neeg muas zaub tau txais cov ntse thiab ntev tshaj plaws hnav tuaj yeem. Peb liCarbide Tuajyog tsim los ntawm cov khoom uas muaj cov qauv submon foob thiab tau dhau mus los ntawm lub ntsag (kub iSostatic xovxwm) txheej txheem los xyuas kom meej cov hnav ntev tshaj plaws thiab hlwv. Txhua tus hniav tseem tau kuaj raws li kev ua haujlwm rau kev tswj kom zoo.
Nws yog qhov txuj ci tseem ceeb rau cov khoom siv carbide kom mus ntawm cov khoom siv riam rau kev lag luam semi-tiav rau cov khoom lag luam semi tiav yog kev tsim khoom ntawm kos duab. XaivMob siab rau Tool®, Xaiv cov Hoobkas zoo WC zoo, yuav yeej koj ntau cov neeg siv khoom zoo.
