Tungsten carbide yog cov khoom siv ntom ntom thiab tawv uas feem ntau siv rau ntau yam kev lag luam vim nws cov khoom tshwj xeeb xws li lub zog, hnav tsis kam, thiab hardness.Txawm li cas los xij, zoo li txhua yam khoom siv, nws tsis yog tag nrho impervious rau imperfections, thiab porosity yog ib qho teeb meem tshwm sim nrogtungsten carbide.
Porosity hauvtungsten carbidehais txog qhov muaj qhov khoob, qhov tawg, lossis qhov khoob hauv cov khoom uas tuaj yeem ua rau nws cov qauv thiab kev ua haujlwm tsis muaj zog.Cov pores no tuaj yeem tshwm sim los ntawm ntau yam, suav nrog cov txheej txheem tsim khoom tsis raug, tsis sib xws ntawm cov khoom siv raw, thiab kev hloov pauv hauv cov txheej txheem sintering.
Porosity hauv tungsten carbide tuaj yeem muaj kev cuam tshuam loj rau cov khoom siv thiab kev ua haujlwm.Cov porosity siab tuaj yeem txo cov khoom siv lub zog, hardness, thiab toughness, ua rau nws yooj yim rau tawg thiab hnav.Tsis tas li ntawd, porosity tuaj yeem cuam tshuam rau cov khoom muaj peev xwm ua kom sov, uas tuaj yeem ua rau muaj teeb meem xws li thermal tawg thiab deformation.
Txhawm rau txo cov porosity hauv tungsten carbide, cov tuam ntxhab tuaj yeem siv cov txheej txheem tshwj xeeb xws li kub isostatic nias, uas tuaj yeem pab kaw qhov pores hauv cov khoom.Kub isostatic nias nrog rau kev siv lub siab thiab qhov kub thiab txias rau cov khoom siv tungsten carbide, uas yuav pab tshem tawm txhua qhov khoob, voids, lossis tawg ntawm cov khoom.Zuag qhia tag nrho,
porosity yog ib qho teeb meem uas cuam tshuam nrog tungsten carbide, tab sis nws tuaj yeem txo qis los ntawm kev siv cov txheej txheem tsim thiab cov txheej txheem, thiab los ntawm kev xaiv cov khoom siv raw khoom zoo.
