Ibikoresho byububumbyi, cyane cyane byerekeranye nububumbyi bwinganda cyangwa ububumbyi bwateye imbere, bikoreshwa mubikorwa bitandukanye byinganda, aho imbaraga za mashini no kurwanya imbaraga ziva hanze (nka ruswa) aribintu byingenzi bisabwa mumikorere.Kurwanya kwambara nigikorwa nyamukuru cyo gupima ibikoresho bya ceramic.Mubisanzwe abantu bakoresha ubukana kugirango bamenye imyambarire nimbaraga za alumina ceramic.Nukuvuga ko, uko gukomera gukomera, niko kwihanganira kwambara.Nigute ushobora kugerageza ibipimo byubukomezi bwibumba-ceramika?
Gukomera nimwe mubintu byingenzi kandi bipimwa kenshi muri alumina ceramics.Irashobora gusobanurwa nkigipimo cyumusaruro wumusaruro wubutaka cyangwa ibikoresho.Gukomera biranga kurwanya ceramic kumeneka, guhindagurika, kwiyegereza no kwimurwa.Muri rusange, uburyo bwa Vickers na Knoop bukoreshwa cyane mugupima ubukana bwibumba.Tekinike ya Vickers niyo isanzwe.Ipima ubukana bwibumba cyangwa ibindi bikoresho mugupima ubunini bwa theindentation yasizwe na indenter.Irakwiriye kubice bito n'ibice bito.Ikoresha indimu ya diyama n'umutwaro woroshye kugirango ikore indentation kubintu bigeragezwa.Agaciro gakomeye karashobora kandi kuba igipimo cyubujyakuzimu bwa indentation yatewe na indenter.
Ukurikije ibikenerwa bitandukanye byisoko kugirango imikorere yububumbyi bwa alumina, Chemshun Ceramics itanga AL2O3 92%, AL2O3 95%alumina yambara ibikoresho bya ceramic birwanya.Ibirimo bya alumina bigira ingaruka ku bukomere bwibikoresho bya ceramic kurwego runaka, ni ukuvuga kwihanganira kwambara.Abakiriya barashobora guhitamo ceramika idashobora kwambara hamwe nibintu bitandukanye bya alumina ukurikije aho bakorera.
