Nws yog paub zoo tias lub hardness ntawmtungsten carbideyog ntau dua li cov hlau zoo tib yam, thiab siab hardness thiab siab hnav tsis kam yog cov yam ntxwv tseem ceeb ntawm cov khoom carbide.Tom qab ntawd qhov kev sim hardness rau txhua pawg ntawm cov khoom dhau los ua ib qho tseem ceeb los xyuas kom meej qhov hardness ntawm cov khoom.
Txhua pawg ntawm peb lub tuam txhab cov khoom yuav raug kuaj los ntawm kev sim cov qauv coj mus kuaj seb puas yog Rockwell hardness mus txog tus qauv.Txhawm rau kom ntseeg tau qhov tseeb ntawm qhov ntsuas, qhov saum npoo ntawm cov hlau yog hauv av tsawg kawg yog 0.2 hli ua ntej ntsuas, thiab qhov roughness Ra yog tsawg dua lossis sib npaug rau 0.2 micron.Vim lub siab hardness ntawm carbide, lub pob zeb diamond indenter yog yooj yim puas, yog li lub pob zeb diamond indenter kuj raug kuaj ua ntej qhov kev xeem kom paub tseeb tias qhov tseeb ntawm kev ntsuas.
Qhov kev sim hardness tuaj yeem cuam tshuam cov khoom siv kho tshuab thiab qhov sib txawv ntawm cov ntaub ntawv carbide nyob rau hauv cov tshuaj sib txawv, ib puag ncig ua haujlwm.Cov khoom tsim nyog tuaj yeem siv rau ntau qhov chaw ua haujlwm hnyav thiab ua si nws qhov kev ua tau zoo dua.
Ltd. ruaj khov tsim kev nco qab ntawm "zoo ua ntej, cov neeg siv khoom ua ntej", kho cov khoom zoo yeej tsis txaus siab thiab siv zog ua kom zoo.Peb tau txiav txim siab los tsim qhov zoo tshaj plawstungsten carbide khoom.
