Tungsten carbide blades
Nrog rau kev xaiv qib zoo, submicron grain loj tungsten carbide hniav tuaj yeem ua rau lub taub hau brittleness nquag cuam tshuam nrog cov carbide. Txawm hais tias tsis yog li poob siab-resistant li steel, carbide yog cov hnav tsis tshua muaj zog, nrog kev tawv tawv sib npaug rau RC 75-80. HNIAV lub neej tsawg kawg yog 50x cov pa hniav sib xyaw ua ke tuaj yeem pom tau yog tias chipping thiab breakage tau zam.
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.
Huaxin carbide sawv npaj txhij los pab koj hauv kev ua tiav qhov zoo tshuav nyiaj li cas ntawm cov khoom uas yuav tso cai rau koj kom tau txais kev ua haujlwm siab tshaj plaws los ntawm koj cov pa carbide.
