Izinto ze-Ceramic, ngokukodwa zibhekisela kwi-ceramics ye-industrial okanye i-ceramics ephezulu, isetyenziselwa kwiindawo ezahlukeneyo zoshishino, apho amandla omatshini kunye nokuchasana nemikhosi yangaphandle (njenge-corrosion) ziimfuno eziphambili zokusebenza.Ukuxhatshazwa kokugqoka yinkcazo yokusebenza eyintloko yokulinganisa izinto ze-ceramic.Ngokuqhelekileyo abantu basebenzisa ubunzima ukuze bagwebe ukumelana nokunxiba kunye namandla e-alumina ceramic materials.Oko kukuthi, ukuphakama kobunzima, bhetele ukuxhathisa ukunxiba.Ngoko ukuvavanya njani iiparitha zobunzima beekeramics ezixhathisayo?
Ukuqina yenye yezona zinto zibaluleke kakhulu kwaye zilinganiswa rhoqo kwii-alumina ceramics.Inokuchazwa njengomlinganiselo woxinzelelo lwesivuno sayo nayiphi na i-ceramic okanye impahla.Ubunzima bubonakalisa ukuxhathisa kwe-ceramic ukwaphuka, ukuguqulwa, ukuxinana kunye nokufuduka.Ngokubanzi, iindlela zeVickers kunye neKnoop zisetyenziswa ngokubanzi kuvavanyo lobulukhuni beeseramikhi.Ubuchule beVickers bobona buxhaphakileyo.Ilinganisa ubulukhuni beeseramics okanye ezinye izinto ngokulinganisa ubungakanani thei-indenter eshiywe yi-indenter.Kufanelekile kwiindawo ezincinci kunye namacandelo amancinci.Isebenzisa i-indenter yedayimane kunye nomthwalo olula ukwenza i-indentation kwizinto ezivavanywayo.Ixabiso lobunzima bunokuba ngumlinganiselo wobunzulu bokulinganisa okubangelwa yi-indenter.
Ngokweemfuno ezahlukeneyo zemarike yokusebenza kwe-alumina ceramics, iChemshun Ceramics ivelisa i-AL2O3 92%, AL2O3 95%I-alumina inxiba izixhobo ze-ceramic ezixhathisayo.Umxholo we-alumina uchaphazela ubunzima bezinto ze-ceramic kwinqanaba elithile, oko kukuthi, ukuchasana nokugqoka.Abathengi banokukhetha i-ceramics engagungqiyo kunye nomxholo ohlukeneyo we-alumina ngokweemfuno zendawo yokusebenza.
