Cemented carbidemuaj qhov hardness siab heev, feem ntau ntawm HRA80 thiab HRA95 (Rockwell hardness A).Qhov no yog vim muaj qee qhov kev faib ua feem ntawm cobalt, npib tsib xee, tungsten thiab lwm cov ntsiab lus ntxiv rau cov cemented carbide, uas ua rau nws muaj kev hnav siab heev thiab hardness.Lub ntsiab nyuaj theem hauv cemented carbide yog tungsten carbide (WC) thiab tungsten carbide cobalt (WC-Co), ntawm cov hardness ntawm WC yog siab heev, txawm harder dua pob zeb diamond.Cov cobalt hauv WC-Co cov khoom tuaj yeem txhim kho qhov toughness thiab corrosion kuj ntawm cov khoom.Nws yuav tsum tau muab sau tseg tias hardness ntawm cemented carbide muaj feem xyuam rau nws cov tshuaj muaj pes tsawg leeg, kev npaj, thaiv ceev thiab lwm yam, thiab hardness ntawm ntau hom cemented carbide yuav txawv.
Cemented carbide muaj siab hardness thiab hnav tsis kam, thiab feem ntau yog siv los txiav cov ntaub ntawv thiab ua cov cuab yeej.Tab sis tsis yog txhua yam khoom siv tau yooj yim txiav los yog ua tiav los ntawm carbide, thiab muaj qee qhov kev txwv.Piv txwv li, txiav kev ua tau zoo ntawmcov cuab yeej carbidetej zaum yuav txawv thaum txiav ntau hom hlau.
Thaum txiav cov hlau hnyav, cov cuab yeej carbide feem ntau xav tau cov txheej txheem tshwj xeeb lossis cov qauv duab geometric los tswj lawv cov kev ua haujlwm.Tib lub sijhawm, cov cuab yeej cemented carbide tsis tuaj yeem txiav cov ntaub ntawv nkig, xws li iav thiab ceramics.Yog li ntawd, cemented carbide tsis yog kiag li tsis muaj kev txwv.Nws yuav tsum tau siv rau hauv cov xwm txheej tshwj xeeb ntawm daim ntawv thov thiab yuav tsum tau ua kom zoo dua qub nrog rau lwm cov ntaub ntawv lossis cov qauv tsim.
