1. Kev nyab xeeb yam
Kev nyab xeeb yam xam los ntawm lub siab, load yam tsis txaus nyob rau hauv txhua rooj plaub. Engineering applications thiab computer simulations txiav txim siab xaiv ntawm kev nyab xeeb yam. Qhov kev nyab xeeb yuav tsum yog ob qho tib si siv tau thiab txaus kom ua tiav txoj haujlwm.
2. siab
Qhov kev xeem flexural zog yog siv los ntsuas qhov tsis kam ntawm cov qib carbide tshwj xeeb rau kev ntxhov siab. Hauv kev tsim cov cemented carbide, nws raug nquahu kom xav txog qhov kev ntxhov siab ntawm cov khoom siv.
3. Kev cuam tshuam tsis kam
Tungsten carbide yog qhov cuam tshuam ntau dua li cov hlau. Qhov loj tshaj plaws cuam tshuam lub zog yog absorbed los ntawm elastic qauv tsim nyob rau hauv cov khoom. Qee lub zog hloov dua siab tshiab los ntawm kev kub thiab kev sib txhuam. Rau cov ntawv thov stamping, nws yog ib qho tseem ceeb uas yuav tsum xav txog kev cuam tshuam los ntawm kev ua haujlwm ntawm cov khoom muaj pes tsawg leeg thaum xaiv cov qib carbide. Qib nrog ib tug loj binder tivthaiv muaj kev cuam tshuam zoo. Nyob rau tib lub sijhawm, nws yog ib qho tseem ceeb kom txo lossis tshem tawm tag nrho cov khoom uas yuav ua rau muaj kev ntxhov siab thaum tsim cov khoom lag luam kev ntxhov siab.
4. Abrasion tsis kam
Piv nrog cov hlau, cemented carbide muaj kev hnav zoo dua. Kev hnav tsis kam ntawm cov khoom siv cemented carbide nyob ntawm qhov loj me ntawm cov hmoov xaiv. Qhov qis dua cov ntsiab lus binder, qhov zoo dua qhov me me, qhov zoo dua qhov hnav tsis kam. Yog tias cov khoom xav tau kev tiv thaiv corrosion thiab ua kom cov npoo ntse ntawm qhov loj, cov qib nrog submicron hais tuaj yeem xaiv.
5. Corrosion kuj
Kev xaiv cov khoom yuav tsum tau coj mus rau hauv tus account qhov chaw ua haujlwm. Txawm tias nyob rau hauv ib puag ncig corrosive. Carbide ua tau zoo dua li lwm cov hlau, tab sis qhov ntawd tsis tau txhais hais tias nws yog inert kiag li. Cobalt nyob rau hauv cemented carbide yog raug rau binder leaching nyob rau hauv cov kua chloride, thiab npib tsib xee yuav muaj corrosion kuj zoo dua cobalt nyob rau hauv qhov chaw no.
