I-ZTA (Zirconia Toughened Alumina) ulwelwesi lwe-ceramiciyinto yobunjiniyela esebenza kahle kakhulu eyenziwe ngokungenisa isigaba se-zirconia (ZrO₂) ku-matrix ye-alumina (Al₂O₃). Lesi sakhiwo esihlanganisiwe sihlanganisa ubulukhuni obukhulu be-alumina nezici zokuqina zokuguqulwa kwesigaba se-zirconia, ngaleyo ndlela sithuthukisa kakhulu ukuqina kokuqhekeka kwento kanye nokumelana nomthelela womshini. Isakhiwo sayo esincane esijwayelekile siyafana futhi siminyene, ngobuningi obukhulu ngokuvamile obungu-≥3.95 g/cm³ kanye nobunzima be-Rockwell (HRA) obungadlula ama-85. Izinto zikhiqizwa ngokucubungula i-powder ecwengisisiwe, ukucindezela kwe-isostatic, kanye nokushisa okuphezulu, okuqinisekisa ukuzinza okuhle ngokomzimba nangokomshini.
Izinzuzo eziyinhloko zalolu hlaka zisekugugeni kwalo okuhle kakhulu nokungagqwali. Ezindaweni zokugqoka zezimboni ezisebenzayo, izinga lokugugika kwe-ZTA ceramic lingaba ngaphansi ngo-30%-50% kunele-ceramics evamile ene-alumina ephezulu. Ukumelana kwayo nokugugika kuzuza ngokuqina okuphezulu okumelana nokusika okurhabaxa kanye nendlela yokumunca amandla emifantu emincane ekhiqizwa ukuguqulwa kwesigaba se-zirconia. Ngesikhathi esifanayo, inokungasebenzi kahle kwamakhemikhali okuphezulu, imelana nokuguguleka okuvela ezingxenyeni eziningi ze-acid kanye ne-alkali (ngaphandle kwe-hydrofluoric acid kanye nama-alkali aqinile ashisayo agxilile). Igcina ukusebenza okuzinzile ngaphansi kokuchayeka isikhathi eside emazingeni okushisa aphezulu (izinga lokushisa eliphezulu lenkonzo kufika ku-850°C) kanye nezimo zokusebenza ezinzima, kanye nokuphila kwenkonzo okudlula kakhulu okwezinto zokuvikela zensimbi zendabuko.
Ulwelwesi lwe-ZTA ceramic lusetshenziswa kabanzi ezimbonini ezigugile kakhulu, okuhlanganisa ukukhiqizwa kwamandla okushisa, izimayini, ukukhiqizwa kwesimende, ukuncibilikisa insimbi, kanye nezinhlelo zokuphatha izinto. Izindawo ezithile zokusetshenziswa zifaka phakathi abahlukanisi bezishingishane, izindololwane zamapayipi, ama-impellers e-fan, ama-chute, ama-hopper, kanye nemishini ehlukahlukene yokuhlukanisa i-powder. Izindlela zayo zokufaka ziyahlukahluka, njengokubopha, ukubhoboza, noma ukushumeka kwe-modular, okuvikela ngempumelelo ama-substrate emishini. Lokhu kunciphisa kakhulu imvamisa yokugcinwa kwesikhashana kanye nezindleko zokukhiqiza ezibangelwa ukuguguleka, kuthuthukisa ukusebenza kahle kohlelo kanye nokuphepha.
Ngamafuphi, ulwelwesi lwe-ZTA alumina ceramic selube yinto ebalulekile kwezobuchwepheshe emkhakheni wokuvikelwa kokugqokwa kwezimboni, ngenxa yomklamo walo ohlanganisiwe owenziwe ngokwesayensi kanye nokusebenza okuhle kakhulu okuqinisekiswayo. Inikeza isiqinisekiso esithembekile sokusebenza okuzinzile kwesikhathi eside kwemishini ezindaweni ezinzima zokuhudula, okunikeza izinzuzo ezinkulu kwezomnotho kanye nenani lokusetshenziswa. Ucwaningo oluqhubekayo ezintweni zokwakha kanye nokucubungula luzokwandisa imikhawulo yalo yokusebenza kanye nobubanzi bezicelo.
