Qhov tsis zoo ntawm cemented carbide feem ntau suav nrog cov ntsiab lus hauv qab no:

Kub tawg qhov tsis xws luag: Carbide yog qhov ua rau kub tawg ntawm qhov kub thiab txias.Qhov no feem ntau yog vim cobalt tuaj yeem hnov ​​​​mob nrog carbides ntawm qhov kub thiab txias los tsim cov theem teeb meem, yog li txo qhov toughness thiab kev ntseeg siab ntawm cov khoom.

Porosity defects:Carbidemuaj pores.Cov teeb meem no yog tshwm sim los ntawm kev cuam tshuam ntawm cov pa roj thaum lub sij hawm kev npaj.Tsis tas li ntawd, qhov ceev ntawm cemented carbide nws tus kheej tsis siab, uas kuj yog ib qho laj thawj rau qhov teeb meem porosity.

Grain ciam teb brittleness: Thaum kub siab, brittle fracture tuaj yeem tshwm sim ntawm cov ciam teb ntawm cemented carbide, thiab qhov tsis xws luag tuaj yeem cuam tshuam rau cov khoom siv.

Yooj yim rau tawg:Carbidemuaj qhov tsis tshua muaj pob txha toughness, thiab microcracks tuaj yeem tshwm sim txawm tias qis qis, ua rau cov khoom tawg.

Yooj yim tawg:Carbidekuj muaj tsis txaus pob txha toughness thiab yuav yooj yim tawg thaum raug kev cuam tshuam loj los yog dabtsi yog khoov loads.

Tsis kub-resistant: thermal stability ntawm cementedcarbideyog neeg pluag.Thaum qhov kub siab tshaj 500 ° C, nws lub koom haum yuav hloov pauv, yog li poob nws qhov kev ua haujlwm qub.

Tsis zoo toughness: Lub toughness ntawmcemented carbidetsis muaj zog dua li lwm yam khoom siv engineering thiab tsis tuaj yeem tiv taus qhov cuam tshuam loj.
