Cov khoom siv cemented carbide feem ntau suav nrog tungsten carbide-based cemented carbide, TiC(N)-based cemented carbide, cemented carbide nrog ntxiv TaC (NbC), thiab ultrafine-grained cemented carbide. Kev ua tau zoo ntawm cov ntaub ntawv cemented carbide feem ntau yog txiav txim siab los ntawm cov theem ntxiv dag zog.
Cemented Carbide nrog Ntxiv TaC (NbC)
Ntxiv TaC (NbC) rau cemented carbide yog ib txoj hauv kev zoo los txhim kho nws cov kev ua tau zoo. Hauv TiC / Ni / Mo alloys, hloov ib feem ntawm TiC nrog carbides zoo li WC thiab TaC, uas muaj kev sib zog zoo dua, txhim kho cov cemented carbide kev ua tau zoo thiab nthuav dav nws cov ntawv thov ntau yam. Qhov sib ntxiv ntawm WC thiab TaC txhim kho:
● Toughness
● Elastic modulus
● Resistance rau yas deformation
● Lub zog kub kub
Nws kuj tseem txhim kho cov thermal conductivity thiab thermal shock resistance, ua rau cov cuab yeej tsim nyog rau kev cuam tshuam kev txiav.In WC-Co alloys, kev ua tau zoo tuaj yeem txhim kho los ntawm kev ntxiv 0.5% mus rau 3% (feem ntau) ntawm carbides xws li TaC, NbC, Cr3C2, VC, TiC, lossis HfC. Lub hom phiaj tseem ceeb suav nrog:
● Grain refinement
● Kev tuav cov qauv siv lead ua zoo ib yam tsis muaj qhov tseem ceeb recrystallization
● Nce hardness thiab hnav tsis kam tsis muaj kev cuam tshuam toughness
Tsis tas li ntawd, cov additives no txhim kho:
● High-temperature hardness
● Lub zog kub kub
● Oxidation kuj
Thaum lub sij hawm txiav, ib tug tawv, nws tus kheej-compensating oxide zaj duab xis cov ntaub ntawv, uas resists nplaum thiab diffusive hnav thaum machining tej yam hlau los yog alloys. Qhov no txhim kho lub cuab yeej hnav tsis kam thiab ua rau nws muaj peev xwm tiv taus crater hnav thiab flank hnav. Cov txiaj ntsig no tau tshaj tawm ntau dua thaum cov ntsiab lus cobalt hauv cemented carbide nce.
● Cemented carbide nrog 1% mus rau 3% (feem feem ntau) TaC (NbC) tuaj yeem siv ntau yam cam khwb cia hlau, nrog rau cov hlau cam khwb cia hard ntxiv thiab alloy cam khwb cia hlau.
● Tsawg-cobalt alloys nrog 3% mus rau 10% (feem feem ntau) TaC (NbC), xws li YG6A, YG8N, thiab YG813, muaj ntau yam. Lawv tuaj yeem ua tau:
Chilled cam khwb cia hlau
Ductile cam khwb cia hlau
Cov hlau tsis muaj hlau
Cov ntaub ntawv nyuaj-rau-tshuab xws li stainless hlau, hardened steel, thiab high-temperature alloys
Cov no feem ntau hu ua General-purpose alloys (YW).Ntau cov ntsiab lus cobalt tsim nyog boosts lub zog thiab toughness ntawm no hom ntawm cemented carbide, ua rau nws haum rau ntxhib machining thiab interrupted txiav ntawm nyuaj-rau-machine cov ntaub ntawv. Cov ntawv thov suav nrog:
● Skinning loj steel castings thiab forgings
● Tig, npaj, thiab milling ntawm austenitic hlau thiab cov hlau tsis muaj cua sov
● Machining nrog loj rake ces kaum, loj txiav seem, thiab nruab nrab mus rau tsawg speeds
● Rough tig rau tsis siv neeg, semi-automatic, thiab ntau lub cuab yeej lathes
● Kev tsim khoom xyaum, iav hobs, thiab lwm yam cuab yeej nrog siab txiav ntug zog **
Nyob rau hauv WC-TiC-Co alloys, ntau TiC cov ntsiab lus nce rhiab heev rau thermal tawg, ua rau ntau dua brittleness. Ntxiv TaC rau qis-TiC, high-cobalt WC-Ti-Co alloys txhim kho:
● Toughness
● Thaum tshav kub kub tsis kam
● Oxidation kuj
Thaum TiC txo cov thermal poob siab tsis kam, TaC them nyiaj rau qhov no, ua rau cov hlau tsim nyog rau kev ua haujlwm milling.Less kim lwm yam xws li NbC los yog Hf-Nb carbides (cov feem ntau: Hf-60%, Nb-40%) tuaj yeem hloov tau rau TaC. Hauv TiC-Ni-Mo alloys, ntxiv TiN, WC, thiab TaC ib txhij txhim kho:
● Hardness
● Flexural zog
● Oxidation kuj
● Thermal conductivity
ntawm qhov kub thiab txias (900-1000 ° C).
Ultrafine-Grained Cemented Carbide
Refining cov nplej ntawm cemented carbide txo cov theem nyuaj, ua rau thaj tsam ntawm cov nplej nyuaj thiab cov khoom sib txuas ntawm cov nplej. Lub binder theem faib ntau tusyees nyob ib ncig ntawm lawv, txhim kho:
Hardness
Hnav tsis kam
Ua kom cov ntsiab lus cobalt kom tsim nyog kuj tseem txhawb zog flexural. Ultrafine-grained cemented carbide, tsim los ntawm cov khoom me me WC thiab Co, ua ke:
Lub siab hardness ntawm cemented carbide
Lub zog ntawm high-speed steel
Grain loj sib piv:
Ordinary cemented carbide: 3-5 μm
General nplua-grained cemented carbide: ~ 1.5 μm
Submicron-grained alloys: 0.5-1 μm
Ultrafine-grained cemented carbide: WC grain loj hauv qab 0.5 μm
Grain refinement txhim kho:
Hardness
Hnav tsis kam
Flexural zog
Chiping kuj
High-kub hardness
Muab piv rau cov cemented carbide zoo tib yam ntawm cov khoom sib xyaw, ultrafine-grained cemented carbide muaj:
Hardness nce ntau tshaj 2 HRA
Flexural zog nce ntawm 600-800 MPa
Yam khoom:
Cov ntsiab lus ntawm cobalt: 9% -15%
Hardness: 90-93 HRA
Flexural zog: 2000-3500 MPa
Cov qib uas tsim nyob rau hauv Suav teb suav nrog YS2 (YG10H, YG10HT), YM051 (YH1), YM052 (YH2), YM053 (YH3), YD05 (YC09), YD10 (YG1101), B60, YG610, YG643, thiab YD05 zoo heev rau nws cov cement. carbide tuaj yeem ua rau hauv av kom ntse txiav cov npoo uas tsis tshua muaj roughness, ua rau nws zoo tagnrho rau cov cuab yeej precision xws li:
Broaches
Reamers
Precision hobs
Nws ua tau zoo hauv machining nrog qhov tob me me ntawm kev txiav thiab pub tus nqi. Nws kuj tseem tsim nyog rau cov cuab yeej me me xws li:
Kev xyaum me me
Me me milling cutters
Me me broaches
Me hobs
Hloov cov cuab yeej siv high-speed steel, nws lub neej ntev yog 10-40 zaug ntev dua, muaj peev xwm tshaj 100 zaug.Ultrafine-grained cemented carbide cov cuab yeej tshwj xeeb yog tsim rau kev ua haujlwm:
Hlau-raws li thiab nickel-based high-temperature alloys
