Izinto ze-Ceramic, ikakhulukazi zibhekisela kuma-ceramics ezimbonini noma izitsha zobumba ezithuthukisiwe, zisetshenziswa emikhakheni ehlukahlukene yezimboni, lapho amandla emishini nokumelana namandla angaphandle (njengokugqwala) kuyizidingo eziyinhloko zokusebenza.Ukumelana nokugqoka kuyinkomba yokusebenza eyinhloko yokulinganisa impahla ye-ceramic.Ngokuvamile abantu basebenzisa ubulukhuni ukuze bahlulele ukumelana nokugqoka namandla ezinto zobumba ze-alumina.Okusho ukuthi, ukuphakama kokuqina, kungcono ukumelana nokugqoka.Ngakho-ke ungahlola kanjani imingcele yobulukhuni be-ceramics resistant?
Ukuqina kungenye yezinto ezibaluleke kakhulu futhi ezivame ukukalwa kuma-alumina ceramics.Kungachazwa njengesilinganiso sokucindezeleka kwesivuno kwanoma iyiphi i-ceramic noma impahla.Ukuqina kubonisa ukumelana kwe-ceramic ukuphuka, ukuguquguquka, ukuminyana kanye nokugudluzwa.Ngokuvamile, izindlela ze-Vickers ne-Knoop zisetshenziswa kakhulu ekuhloleni ubulukhuni bezitsha zobumba.Indlela ye-Vickers ivame kakhulu.Ikala ubulukhuni bezitsha zobumba noma ezinye izinto ngokulinganisa usayizi we theukuhlehlisa okushiywe yi-indenter.Ifanele izingxenye ezincane nezingxenye ezincane.Isebenzisa i-indenter yedayimane kanye nomthwalo omncane ukuze idale ukuhlehlisa kokubalulekile okuhlolwayo.Inani lokuqina lingase libe isilinganiso sokujula kokuhlehlisa okubangelwa i-indenter.
Ngokwezidingo ezihlukene zemakethe zokusebenza kwe-alumina ceramics, iChemshun Ceramics ikhiqiza i-AL2O3 92%, AL2O3 95%i-alumina igqoka izinto zobumba eziqinile.Okuqukethwe kwe-alumina kuthinta ubulukhuni bezinto ze-ceramic ngezinga elithile, okungukuthi, ukumelana nokugqoka.Amakhasimende angakhetha ama-ceramics angagugi anokuqukethwe okuhlukile kwe-alumina ngokuya ngezidingo zendawo yokusebenza.
