* Hardness
Lub hardness ntawm cov khoom yog txhais raws li lub peev xwm los tawm tsam cov tawv Pressed rau saum npoo ntawm cov khoom.Mainly siv kev ntsuas ntawm Rockwell thiab vickers.Raws li cov hauv paus ntsiab lus ntawm Vickers thiab Rockwell cov kev xeem sib txawv, kev saib xyuas yuav tsum tau ua thaum hloov los ntawm ib qho mus rau lwm qhov.
* Coercive Field Strength
Coercive teb lub zog yog ib qho kev ntsuas ntawm qhov seem hlau nplaum nyob rau hauv lub hysteresis voj thaum lub cobalt (Co) binder nyob rau hauv qib ntawm cemented carbide yog magnetized thiab ces demagnetized.Nws tuaj yeem siv los ntsuas cov xwm txheej ntawm lub koom haum alloy .Qhov zoo dua cov nplej loj ntawm cov carbide theem siab dua yuav yog tus nqi quab yuam.
* Sib nqus saturation
Sib nqus Saturation: yog qhov sib nqus sib nqus rau qhov zoo.Sib nqus Saturation ntsuas ntawm cobalt (Co) binder theem nyob rau hauv cemented carbide yog siv los ntawm kev lag luam los ntsuam xyuas nws cov muaj pes tsawg leeg.Low magnetic Saturation qhov tseem ceeb qhia tau hais tias muaj cov pa roj carbon tsawg thiab los yog muaj Eta-phase carbide.high magnetic saturation qhov tseem ceeb qhia tias muaj. "dawb carbon" los yog graphite.
* Ceev
Lub qhov ceev (tshwj xeeb nqus tau) ntawm cov khoom siv yog qhov sib piv ntawm nws lub ntim .it siv cov ntsiab lus carbide
* Transverse Rupture zog
Transverse Rupture Strength (TRS) yog lub peev xwm ntawm cov khoom siv los tiv thaiv bending.measured ntawm qhov tawg ntawm cov khoom hauv ib qho qauv peb taw tes khoov.
* Metallographic Analysis
Cobalt Lakes yuav sib cog lus tom qab sintering, ntau tshaj cobalt tej zaum yuav muaj nyob rau hauv tej cheeb tsam ntawm cov qauv.forming lub pas dej cobalt, yog tias lub sij hawm sib txuas tsis tiav, yuav muaj ib co residual pores, Cobalt pas dej ua ke thiab porosity yuav kuaj tau los ntawm kev siv metallographic microscope.
