I-Zirconia yaqinisa i-alumina, eyaziwa ngokuba yi-ZTA yinto edibanisa i-alumina kunye ne-zirconia. Le ngxubevange yeyeqela leeseramics ezibizwa ngokuba yi-AZ composite.
Iimpawu ezichukumisayo ze-ZTA
I-alumina eqinile yeZirconia ivelele ngenxa, kwiipropati zayo. Ifumana ukusetyenziswa kwizicelo zokusika izixhobo kunye nemimandla eyahlukeneyo yezonyango. Amandla aphezulu, ubunzima, ukuqina, ubulukhuni kunye nokumelana nokunxiba kwee-AZ composites kubenza bafaneleke kakhulu, kwezi zicelo.

Ubume be-ZTA
I-Zirconia yaqinisa i-alumina (ZTA) iyaziwa ngamandla ayo xa ithelekiswa ne-alumina ecocekileyo. La mandla avela ekuguqulweni kweenkozo ze-zirconia xa ziphantsi koxinzelelo.
Uxinzelelo lwenze iNguquko Toughening
Amandla e-ZTA ayanda, ngenkqubo ebizwa ngokuba yi-stress induced transformation toughening. Le nkqubo idala iingxaki ezikhokelela ekuqhekekeni kwisakhiwo se-zirconium esivumela iinqununu ze-zirconium ukuba zitshintshe izigaba kwaye zihambe ngokukhululekile phakathi kweengqungquthela ze-alumina..
I-Versatility ye-ZTA
I-ZTA ibonisa uluhlu lweepropati eziyenza ibe yimathiriyeli exabisekileyo kwizicelo. Kwishishini lifumana ukusetyenziswa njengesixhobo sokutshintsha okudibeneyo kunye neenjongo zokubuyisela kwisimo sangaphambili.
I-ZTA kuShishino lwezoNyango
Ii-ZTAs ezixhathisayo zokunxiba ziyenza ilungele ukuvelisa izifakelo zokusebenza eziphezulu. Amandla ayo akhethekileyo kunye nokumelana nomhlwa kuyenza ikwazi ukumelana nemithwalo ngaphandle kokuthotywa iyenze ilungele izicelo zokuthwala umthwalo..
I-ZTA kwiZixhobo zokusika
Ngenxa yokuqina kwayo i-ZTA iqhele ukuqeshwa kwizixhobo zokusika ecaleni kweefom ze-alumina kwizicelo zokusika isinyithi..
I-ZTA kumacandelo eNjini
amacandelo enjini, izinto zelebhu, ii-crucibles zamashishini kunye neetyhubhu eziphikisayo zingenziwa zonke kusetyenziswa i-ZTA.
I-ZTA kwi-sandblasting
I-Zirconia yaqinisa i-alumina, eyaziwa ngokuba yi-ZTA ingasetyenziswa kwizicelo, njengokuqhunyiswa kwesanti.
Enye yeenzuzo ze-ZTA kukusebenza kwayo kweendleko. Iwela phakathi koluhlu lwexabiso le-Alumina kunye neZirconium iyenza ifikeleleke ngakumbi xa kuthelekiswa nezinto.. Ukuqina kwayo okuphuculweyo kokwaphuka kuyenza ifaneleke kakuhle kumacandelo afumana ukulayisha okuchaphazelekileyo.Enye iadvanteji ye-ZTA kukuqhuba kwayo kuvumela ukuchithwa kobushushu okusebenzayo okubangelwa kukukhuhlana.. Ukongeza inkqubo ye-sintering iphumela kwi-microstructure ephucula ukusebenza kokunxiba.Ukushwankathela i-zirconia eqinile i-alumina yimali esebenzayo eneempawu eziluncedo kumashishini ahlukeneyo.. Amandla ayo kunye nokuqina kwayo kudityaniswe nokuxhathisa okugqwesileyo kokunxiba kunye nokuhanjiswa kwe-thermal kuyenza ibe lolona khetho lufanelekileyo kwimimandla ukusuka kunyango ukuya kwimveliso..
