Ua ntej ntawm tag nrho cov, hnav tsis kam ntawm cemented carbide txias hau pwm yog ze ze rau hardness ntawm nws cov khoom. Cov ntaub ntawv carbide yog cov khoom sib xyaw tsim los ntawm cov hlau carbide hais (xws li tungsten carbide lossis titanium carbide) hauv cov hlau (feem ntau yog cobalt) matrix. Cov khoom siv no muaj qhov nyuaj siab heev, feem ntau ntawm 900 thiab 2200HV. Lub siab hardness ntawm cov khoom siv cemented carbide muab cov kab mob khaub thuas pwm zoo hnav tsis kam, uas tuaj yeem tiv taus hnav hauv qab kev sib txhuam nrog cov ntaub ntawv hlau thiab txuas ntxiv lub neej kev pab cuam ntawm pwm.
Qhov thib ob, kev hnav tsis kam ntawm cemented carbide txias hau pwm yog ze rau nws lub koom haum thiab cov qauv. Lub koom haum zoo thiab cov qauv tuaj yeem txhim kho lub zog thiab qaug zog tiv thaiv ntawm cemented carbide, yog li tswj kev ruaj khov thiab kav ntev ntawm pwm. Carbide Moulds yog precision machised thiab feem ntau yog muaj cov qauv ntom ntom thiab tsim kom zoo theem muaj pes tsawg leeg, yog li kev txhim kho lawv cov coj tsis kam.
Tsis tas li ntawd, kev hnav tsis kam ntawm cemented carbide txias hau pwm kuj cuam tshuam los ntawm lwm yam. Piv txwv li, kev siv cov roj nplua nyeem uas tsim nyog tuaj yeem txo qhov kev sib cuag ncaj qha ntawm cov pwm thiab cov khoom siv hlau, txo kev sib txhuam thiab hnav, thiab txuas ntxiv lub neej kev pab cuam ntawm pwm. Tsis tas li ntawd, qhov tsim nyog ua kom txias thiab txaus condensation tuaj yeem txo qhov kub ntawm pwm, txo cov kev ntxhov siab thermal, thiab txhim kho qhov hnav tsis kam ntawm cemented carbide txias hau pwm.
