Tungsten Carbide Hniav
Yog xaiv qib zoo tshaj plaws, cov hniav tungsten carbide uas loj li submicron tuaj yeem ua kom ntse mus txog ntug razor yam tsis muaj qhov brittleness uas feem ntau cuam tshuam nrog cov carbide ib txwm muaj. Txawm hais tias tsis tiv taus kev co zoo li hlau, carbide tiv taus kev hnav heev, nrog rau qhov nyuaj sib npaug rau Rc 75-80. Lub neej ntawm cov hniav tsawg kawg yog 50X cov hlau hniav ib txwm muaj yog tias tsis txhob muaj kev tawg thiab tawg.
Ib yam li kev xaiv hlau, kev xaiv qib zoo tshaj plaws ntawm tungsten carbide (WC) yog ib qho txheej txheem nyuaj uas muaj kev xaiv tsis zoo ntawm kev hnav tsis kam thiab kev tawv/kev poob siab tsis kam. Cemented tungsten carbide yog ua los ntawm sintering (ntawm qhov kub siab) kev sib xyaw ua ke ntawm tungsten carbide hmoov nrog hmoov cobalt (Co), ib qho hlau ductile uas ua haujlwm ua "binder" rau cov khoom tungsten carbide nyuaj heev. Qhov kub ntawm cov txheej txheem sintering tsis cuam tshuam nrog kev cuam tshuam ntawm 2 cov khoom sib xyaw, tab sis ua rau cobalt mus txog lub xeev ze-kua thiab ua zoo li cov kua nplaum encapsulating rau cov khoom WC (uas tsis cuam tshuam los ntawm qhov kub). Ob qho kev ntsuas, uas yog qhov sib piv ntawm Cobalt rau WC thiab qhov loj me ntawm WC, tswj hwm cov khoom siv loj ntawm cov khoom "cemented tungsten carbide" uas tshwm sim.
Kev teev qhov loj ntawm WC cov khoom me me thiab feem pua ntawm Cobalt ntau yuav ua rau muaj qhov tsis kam rau kev co (thiab muaj zog cuam tshuam siab). Qhov loj ntawm WC cov noob me me (yog li ntawd, qhov ntau ntawm WC thaj chaw uas yuav tsum tau coated nrog Cobalt) thiab qhov tsawg dua Cobalt siv, qhov nyuaj dua thiab tiv taus kev hnav ntau dua qhov tshwm sim yuav dhau los ua. Txhawm rau kom tau txais kev ua tau zoo tshaj plaws los ntawm carbide ua cov khoom siv hniav, nws yog ib qho tseem ceeb kom tsis txhob muaj kev puas tsuaj ntawm ntug ua ntej los ntawm kev tawg lossis tawg, thaum tib lub sijhawm ua kom ntseeg tau tias qhov zoo tshaj plaws tiv taus kev hnav.
Ua ib qho teeb meem tiag tiag, kev tsim cov ntug txiav ntse heev, cov ces kaum ntse ntse qhia tias yuav tsum siv cov carbide zoo rau hauv cov ntawv thov hniav (kom tiv thaiv cov qhov loj thiab cov npoo ntxhib). Muab kev siv carbide uas muaj qhov nruab nrab ntawm 1 micron lossis tsawg dua, kev ua haujlwm ntawm cov hniav carbide; yog li ntawd, feem ntau cuam tshuam los ntawm % ntawm Cobalt thiab cov qauv ntug uas tau teev tseg. Cov ntawv thov txiav uas muaj qhov nruab nrab mus rau qhov siab tshaj plaws yog qhov zoo tshaj plaws los ntawm kev teev tseg 12-15 feem pua Cobalt thiab cov qauv ntug uas muaj lub kaum sab xis ntawm ntug ntawm kwv yees li 40º. Cov ntawv thov uas muaj cov khoom sib dua thiab muab qhov tseem ceeb rau lub neej hniav ntev yog cov neeg sib tw zoo rau carbide uas muaj 6-9 feem pua cob thiab muaj lub kaum sab xis ntawm ntug hauv qhov ntau ntawm 30-35º.
HUAXIN CARBIDE sawv ntsug los pab koj kom ua tiav qhov sib npaug zoo tshaj plaws ntawm cov khoom uas yuav ua rau koj tau txais kev ua tau zoo tshaj plaws los ntawm koj cov hniav carbide.
HUAXIN CARBIDE muaj kev xaiv ntawm cov hniav txiav carbide uas muaj cov khoom siv sib xyaw ua ke
