Feem ntau thaum peb tham txog cov khoom ntawmxim av aluminium oxideabrasives, peb feem ntau hais txog hardness, cov ntsiab lus, thiab lwm yam. Cov qib sib txawv ntawm cov xim av fused alumina muaj qhov sib txawv hardness, tab sis tsis tshua hais txog nws lwm yam khoom-toughness. Tab sis qhov tseeb, qhov toughness ntawm xim av fused alumina kuj yog ib qho khoom tseem ceeb heev. Tom qab ntawd cia peb tham txog qhov toughness no txhais li cas rau xim av aluminium oxide.
Ua ntej tshaj plaws, cia peb nkag siab tias lub tswvyim ntawm toughness yog dab tsi. Lub toughness ntawm abrasives hais txog lub peev xwm ntawm abrasive hais los tiv thaiv crushing nyob rau hauv qhov kev txiav txim ntawm kev sib tsoo quab yuam. Nws yog tus cwj pwm ntawm lub peev xwm ntawm abrasives los tiv thaiv kev cuam tshuam thiab nqus lub zog.
Yog tias xim av aluminium oxide muaj qee qhov tawv, nws yuav ua kom nws lub neej kev pab. Nyob rau tib lub sijhawm, toughness kuj muaj kev cuam tshuam zoo rau nws tus kheej-sharpening ntawm xim av fused alumina. Lub zog muaj zog, qhov tsis tshua muaj xim av aluminium oxide yog tawg, tab sis nws yooj yim rau blunted thiab sib tsoo quab yuam txo. Ob lub luag haujlwm yog kev sib koom ua ke.
Ntawm chav kawm, kuj muaj ib qho kev ntsuas rau lub toughness ntawmxim av fused alumina, uas tsis tuaj yeem txuas ntxiv mus tsis kawg, vim yog qhov tsis sib xws ntawm qhov toughness thiab nws tus kheej-sharpening ntawm xim av aluminium oxide, yog li nws yog ib qho tsim nyog los txiav txim siab qhov sib npaug ntawm qhov toughness thiab nws tus kheej-sharpening raws li tus kheej xav tau.
