Cemented Carbide Studs PM Sintered Parts
Tungsten carbide cement studs tau siv dav hauv cov khoom siv raw cov ntaub ntawv hauv kev lag luam cement. Vim nws ruaj khov npaum li cas thiab kev pab lub neej ntev, cemented carbide cement studs tau dav siv nyob rau hauv raw khoom rau cov menyuam presses hauv kev lag luam cement. Vim nws qhov ruaj khov tus nqi ntau lawm thiab lub neej ua haujlwm ntev, nws tau nyiam los ntawm kev lag luam cement.

Tungsten carbide cement studs tau siv dav hauv cov khoom siv raw cov ntaub ntawv hauv kev lag luam cement. Vim nws ruaj khov npaum li cas thiab kev pab lub neej ntev, cemented carbide cement studs tau dav siv nyob rau hauv raw khoom rau cov menyuam presses hauv kev lag luam cement. Vim nws qhov ruaj khov tus nqi ntau lawm thiab lub neej ua haujlwm ntev, nws tau nyiam los ntawm kev lag luam cement. Cov studs siv nyob rau hauv cov menyuam xovxwm yog ua los ntawm tungsten-cobalt cemented carbide, nrog tungsten carbide (WC) raws li cov matrix thiab cobalt (CO) raws li lub binder theem. Nws yog ua los ntawm cov hmoov hlau metallurgy nrog siab hardness, siab zog, thiab muaj kev cuam tshuam zoo. hnav-resistant cov ntaub ntawv. HRA hardness ntawm cemented carbide studs yog hais txog 87, uas tuaj yeem txhim kho lub neej kev pab cuam thiab kev ua haujlwm zoo ntawm cov menyuam xovxwm, thiab muaj kev hnav tsis kam. Txaus siab los ntawm kev lag luam cement.

Nta
1. Cov ces kaum yog sib npaug thiab chamfered kom tsis txhob muaj kev puas tsuaj hauv zos thaum lub sijhawm tsim khoom, kev thauj mus los, kev teeb tsa, thiab siv.
2. Lub sintering adopts overpressure sintering, cov khoom muaj qhov ntom ntom zoo thiab lub zog siab.
3. Cemented carbide studs PM sintered qhov chaw txais yuav cov txheej txheem tshwj xeeb los tshem tawm cov kev ntxhov siab saum npoo tom qab ua cov khoom lag luam thiab ua kom cov tawv tawv nce rau tib lub sijhawm.
Lub ntsiab kev ua tau zoo ntawm tungsten-cobalt cemented carbide studs muaj xws li hardness, flexural zog, cuam tshuam toughness, thiab flexural magnetism. Feem ntau hais lus, qhov siab dua qhov hardness ntawm cov khoom, qhov zoo dua qhov hnav tsis kam; qhov siab dua qhov khoov lub zog, qhov zoo dua qhov qaug zog; qhov zoo dua qhov cuam tshuam toughness ntawm cemented carbide studs, yog li qhov zoo dua qhov tawg tsis kam. Muaj ntau yam uas cuam tshuam rau qhov Performance index ntawm tungsten-cobalt cemented carbide studs. Piv txwv li, qhov siab dua cov ntsiab lus cobalt, qhov siab dua qhov khoov lub zog thiab cuam tshuam toughness, thiab cov txheeb ze hardness thiab dabtsi yog khoov lub zog yuav txo tau raws li.
Yog li ntawd, tsuas yog los ntawm kev xaiv cov cemented carbide studs uas ua tau raws li qhov kev ua tau zoo ntawm cov ntawv thov tshwj xeeb tuaj yeem ua rau lub neej kev pabcuam ntawm cov menyuam xovxwm tuaj yeem ua tiav. Nws yog qhov zoo tshaj los txiav txim siab cov khoom siv raw khoom raws li qhov chaw ua haujlwm ntawm cov cemented carbide stud.
Cemented carbide, raws li kev lag luam hniav, siv ib los yog ntau tshaj carbides ntawm refractory hlau (WC, TiC, thiab lwm yam) raws li ib tug nyuaj theem, thiab kev hloov hlau (Co, thiab lwm yam.) Raws li ib tug multi-theem khoom rau txiav cemented carbide cov cuab yeej, Feem ntau siv carbide yog WC, TiC, TaC, NbC, thiab lwm yam., thiab feem ntau siv binder theem yog Co, Ni, Fe, thiab lwm yam. Lub zog ntawm cemented carbide feem ntau yog nyob ntawm qib binder Cov ntsiab lus ntawm cemented carbide muaj qhov zoo ntawm qhov siab. lub zog, siab hardness, hnav tsis kam, corrosion kuj, siab kub kuj, thiab me me linear expansion coefficient. Nws yog dav siv nyob rau hauv ntau cov kev lag luam ntau lawm thiab kev ua haujlwm thiab yog ib qho ntawm cov khoom siv zoo tshaj plaws.
