Thaum peb feem ntau 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 aluminium oxide 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 aluminium oxide kuj yog ib qho khoom tseem ceeb heev. Tom ntej no, cia peb tham txog qhov toughness txhais tau li cas rau xim av fused alumina.
Ua ntej, cia peb nkag siab lub tswvyim ntawm toughness. Lub toughness ntawm abrasives hais txog lub peev xwm ntawm abrasive hais los tiv thaiv kev tawg nyob rau hauv qhov kev txiav txim ntawm kev sib tsoo quab yuam. Nws yog ib qho cuab yeej ntawm abrasive lub peev xwm 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 sij hawm, toughness kuj muaj kev cuam tshuam zoo rau tus kheej-sharpening ntawm xim av aluminium oxide. Qhov muaj zog ntawm qhov toughness, qhov tsawg dua cov xim av fused alumina 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.
Tau kawg, kuj tseem muaj kev ntsuas rau lub zog ntawm cov xim av aluminium oxide, uas tsis tuaj yeem txuas ntxiv mus tsis kawg, vim yog qhov tsis sib xws ntawm cov tawv tawv thiab nws tus kheej-sharpening.xim av fused alumina. Yog li ntawd, nws yog ib qho tsim nyog los txiav txim siab qhov sib npaug ntawm qhov toughness thiab nws tus kheej sharpening raws li ib tus neeg xav tau.
