Aluminium kuleyliye ah

Buuxiye gudbinta kulaylka sida magaciisu tilmaamayo waxaa lagu daraa walxaha matrix-ka ee loo isticmaalo in lagu kordhiyo gudbinta kulaylka ee buuxinta walxaha, alumina-da buuxinta gudbinta kulaylka ee caadiga ah ee loo isticmaalo alumina, magnesium oxide, zinc oxide, aluminium nitride, boron nitride, silicon carbide, iwm. Kuwaas waxaa ka mid ah, gaar ahaan micron alumina, budada silicon oo ah jirka ugu weyn. Qaab-dhismeedka alumina wuxuu saameyn weyn ku leeyahay gudbinta kulaylka ee alumina. Budada alumina ultrafine ee wareegsan waa budo micron ah, oo leh gudbin kuleyl sare, dahaadh sare, adkaansho sare, iska caabin heerkul sare, iska caabin xoqid, iska caabin daxalka, iyo astaamo kale; Nadiifnimo sare, qaab wanaagsan, xasillooni wanaagsan, qaybinta cabbirka walxaha cidhiidhiga ah, oo leh xaddi yar oo buuxin ah si loo helo gudbin kuleyl sare. Hordhac alumina gudbinta kulaylka: alumina gudbinta kulaylka waa crystal budo cad oo laga soo saaro heerkul sare. Waxaa jira budo badan oo crystalline ah oo alumina ah, laakiin alumina loo isticmaalo gudbinta kulaylka waxaa ka mid ah alumina wareegsan (taxanaha zf-kq), alumina wareegsan (taxanaha zf-kk), alumina isku dhafan (zf-kqm, taxanaha KCM), iwm. Alumina-da kulaylka gudbisa waa inay lahaataa astaamaha qaybinta cabbirka walxaha cidhiidhiga ah, xasilloonida cabbirka walxaha wanaagsan, qiimaha K ee kulaylka gudbisa oo sarreeya iyo tirada badan ee jajabyada buuxinta ka dib wax ka beddelka isku xirka. Guud ahaan, celceliska cabbirka walxaha alumina-da kulaylka gudbisa waxaa lagu xakamayn karaa qiyaastii 5um, kulaylka gudbisa kulaylkana wuxuu gaari karaa inta u dhaxaysa 3-10w /mk iyadoo loo eegayo xaddiga buuxinta kala duwan.
