Ibumba rya alumina ryakozwe neza: ibikoresho bigezweho bifite imikorere myiza cyane

Ibumba rya alumina rikoreshwa cyane mu nzego nyinshi bitewe n'ibyiza byaryo nko gukomera cyane no kudahinduka cyane mu binyabutabire. Ariko, kudakomera kwaryo kugabanya igihe cyo gukoresha. Ibumba rya alumina ryaravutse kandi rikemura iki kibazo neza.

 Ibumba rya alumina ryakozwe nezabishobora gukomera mu buryo butandukanye. Ibimenyerewe harimo gukomera kwa zirconia, binongera cyane gukomera binyuze mu kongeramo ZrO₂ kuri alumina no gukoresha uburyo bwayo bwo guhindura imiterere n'izindi nzira; gukomera kwa wisker na fibre, kongeramo SiC, Si₃N₄ wisker cyangwa C, fibres za SiC kugira ngo byongere imiyoboro yo gukwirakwiza imyanda no gukoresha imbaraga zo gucika; gukomera kwa wisker ni ukongeramo uduce twinshi twa modulus nka SiC na TiC kugira ngo duhindure kandi duce duto.

 Imbaraga zo guhindagurika n'imbaraga z'ingufu za keramike za alumina zikomeye zirarushaho kwiyongera. Urugero, imbaraga zo guhindagurika za keramike za alumina zikomeye za zirconia zishobora kugera kuri 480MPa, kandi imbaraga zo guhindagurika ni 7MPam1/2.

 Mu bijyanye n'ikoreshwa ryayo, mu rwego rw'ubuvuzi, ikoreshwa mu gukora implants z'amenyo n'ingingo z'ubukorano kubera ko ihura neza n'ibinyabuzima kandi ikaba ikomeye cyane, ibyo bikaba bishobora kugabanya ingorane; mu rwego rwa semiconductor, nk'igikoresho cyo gupakira, ikoreshwa mu bikoresho by'amashanyarazi bya IGBT, nibindi bitewe n'uburyo ikoresha ubushyuhe bwinshi, irinda ubushyuhe n'imbaraga za mekanike; mu bikoresho byo gukata, ishobora kuguma ihamye mu bushyuhe bwinshi no gutunganya ibyuma n'ibyuma bivanze. Ibumba rya alumina rikaze ririmo kurabagirana mu nzego nyinshi bitewe n'imikorere yaryo myiza. Ibumba rya Chemshun ritanga ibumba rya alumina rikaze rifite ubushobozi bwo kwirinda kwangirika kw'ifunguro rya nimugoroba ndetse rikanarwanya ingaruka ku buryo bwo gufata ibikoresho byinshi.
