Qhov sib txawv ntawm cemented carbide thiab tungsten steel

Tungsten steel: Cov khoom tiav muaj li ntawm 18 feem pua ​​​​tungsten alloy hlau. Tungsten steel belongs rau hard alloy, tseem hu ua tungsten-titanium alloy. Lub hardness yog Vickers 10K, thib ob tsuas yog pob zeb diamond. Vim li no, tungsten steel khoom (tungsten steel watches muaj ntau) tsis yooj yim rau hnav. Nws feem ntau yog siv rau ntawm cov cuab yeej tshuab dhos, cuam tshuam cov khoom laum, iav cutter taub hau, thiab pobzeb cutters. Nws muaj zog thiab tsis ntshai ntawm annealing, tab sis nkig.
Cemented carbide: belongs rau thaj tsam ntawm hmoov metallurgy. Cemented carbide, tseem hu ua cermet, feem ntau yog tsim los ntawm cov hlau carbide (WC, TaC, TiC, NbC, thiab lwm yam) lossis hlau oxides (xws li Al2O3, ZrO2, thiab lwm yam), ntxiv rau cov hmoov hlau hlau (Co, Cr, Mo, Ni, Fe, thiab lwm yam) ua los ntawm hmoov metallurgy txoj kev, ceramics nrog tej yam ntxwv ntawm hlau. Cobalt (Co) yog siv los ua kom muaj kev sib raug zoo hauv cov hlau, uas yog, thaum lub sij hawm sintering, nws tuaj yeem nyob ib puag ncig thiab nruj nreem khi cov tungsten carbide (WC) hmoov ua ke, thiab tom qab txias, nws yuav nyuaj Alloy. (Cov nyhuv sib npaug rau cov cement hauv pob zeb). Cov ntsiab lus nquag: 3 feem pua ​​--30 feem pua ​​​​tungsten carbide (WC) yog cov khoom tseem ceeb uas txiav txim siab qee cov khoom hlau ntawm cov cemented carbide lossis cermet, suav txog 70 feem pua ​​--97 feem pua ​​(qhov hnyav piv) ntawm tag nrho cov muaj pes tsawg leeg . Nws yog dav siv rau hnav tsis kam, kub tsis kam, corrosion kuj, qhov chaw los yog riam nrog hnyav ua hauj lwm ib puag ncig, ntawm lub cutter taub hau ntawm lub cuab tam.
Tungsten steel belongs rau cemented carbide, tab sis cemented carbide tsis tas tungsten hlau. Tam sim no cov neeg siv khoom hauv Taiwan thiab cov tebchaws Esxias sab hnub tuaj nyiam siv lo lus tungsten steel. Yog tias koj tham nrog lawv ua tib zoo, koj yuav pom tias feem ntau ntawm lawv tseem hais txog cov tawv tawv. hlau alloy.
Qhov txawv ntawm tungsten steel thiab cemented carbide yog tias nws tseem hu ua high-speed steel lossis cuab yeej hlau. Feem ntau 15-25 feem pua ​​; thaum cemented carbide yog sintered nrog tungsten carbide ua lub ntsiab lub cev thiab cobalt los yog lwm yam sib txuas hlau los ntawm hmoov metallurgy technology, thiab nws cov ntsiab lus tungsten feem ntau yog siab tshaj 80 feem pua. Cias muab, txhua yam uas muaj hardness tshaj HRC65 tuaj yeem hu ua cemented carbide ntev npaum li lawv yog alloys. Tungsten steel tsuas yog ib hom cemented carbide nrog hardness ntawm HRC85 thiab 92, uas feem ntau yog siv los ua riam.
