Incazelo emfushane

I-Fused Alumina-Zirconia ikhiqizwa esithandweni se-arc sikagesi esishisa kakhulu ngokuhlanganisa isihlabathi se-zirconium quartz ne-alumina.Ibonakala ngesakhiwo esiqinile nesiminyene, ukuqina okuphezulu, ukuzinza okuhle kokushisa.Ilungele ukukhiqiza amasondo amakhulu okugaya ensimbi kanye ne-Foundry snagging, amathuluzi amboziwe kanye nokuqhunyiswa kwamatshe, njll.

Iphinde isetshenziswe njengesengezo kuma-Continuous casting refractories.Ngenxa yokuqina kwayo okuphezulu isetshenziselwa ukunikeza amandla eMechanical kulawa ma-refractories.

Inqubo Yokukhiqiza Nesicelo

I-Fused Alumina--I-Zirconia ikhiqizwa esithandweni se-arc sikagesi esishisa kakhulu ngokuhlanganisa isihlabathi se-zirconium quartz ne-alumina.Ibonakala ngesakhiwo esiqinile nesiminyene, ukuqina okuphezulu, ukuzinza okuhle kokushisa.Ilungele ukukhiqiza amasondo amakhulu okugaya ensimbi kanye ne-Foundry snagging, amathuluzi amboziwe kanye nokuqhunyiswa kwamatshe, njll.

Iphinde isetshenziswe njengesengezo kuma-Continuous casting refractories.Ngenxa yokuqina kwayo okuphezulu isetshenziselwa ukunikeza amandla eMechanical kulawa ma-refractories.

I-Yttria-Tetragonal Zirconia Polycrystals (Y-TZP) ne-Alumina (Al2O3) idonse ukunakwa okubalulekile kobuchwepheshe bokufakelwa kwezinto ezibonakalayo ngenxa yokuhlanganiswa kwazo okuhle kwezakhiwo, njengokuqina okuphezulu, ukuqina kokuphuka, namandla aphezulu nokuqina , Lezi zici zizenzile. izinto ezikhangayo zohlelo olubanzi lwezinhlelo zokusebenza ezimboza uhla lwe-biomedical lapho evame ukusetshenziswa khona ezinsizeni zamazinyo njengama-abutments okufakelwa okufakelwa, amabhuloho, izigxobo zezimpande, nomqhele we-ceramic.Ngaphandle kwalokho, ziphinde zisetshenziswe ezinhlelweni zobunjiniyela ezahlukahlukene kufaka phakathi izinzwa ze-oxygen, i-thermal barrier coatings, amathuluzi okusika, izixhumi ze-fiber optical, namaseli kaphethiloli we-oxide aqinile.Kuyaphawuleka ukuthi ukuthuthukiswa kwezakhiwo zemishini ye-Y-TZP kubangelwa usayizi wayo wokusanhlamvu ocolekile noguquko lwesigaba se-tetragonal ukuya kwese-monoclinic.Lokhu kuguqulwa kwesigaba kuhambisana nokukhuphuka kwevolumu cishe ngo-3-5% okuholela ekuvimbeleni ukusakazeka kokuqhekeka futhi ngaleyo ndlela kuthuthukise ukuqina kwempahla.Nokho, kubalulekile ukuqaphela ukuthi lolu shintsho lungenzeka ngokuzenzakalelayo ngaphansi kwezimo ezithile.Uma i-zirconia ibhekene nezinga lokushisa eliphansi endaweni enomswakama ophakathi kuka-100 ℃ no-300 ℃, okungase kuholele ekuwohlokeni kwe-zirconia, okuholela ekuqineni nasekuqhekekeni okuncane.Lesi senzakalo saziwa ngokuthi ukuguga kwe-hydrothermal noma i-Low-Temperature Degradation (LTD) futhi ikhonjwe njengesici esinomthelela ekusebenzeni okuncishisiwe kwezingxenye ze-zirconia ekusetshenzisweni kwamathambo.

Abacwaningi baye bahlakulela izinhlanganisela eziningana lapho i-alumina ihlanganiswa khona nesakhiwo se-zirconia.Inhloso yalokhu kuhlanganiswa ukuthuthukisa ukumelana kwe-LTD kanye nokukhulisa izici ezihlukile zalezi zitsha zobumba ukuze kuthuthukiswe izakhiwo zemishini ye-tetragonal zirconia matrix Ngakolunye uhlangothi, ukuba khona kwe-alumina ku-matrix kudlala indima ebalulekile ekwakheni isakhiwo esiqinile esiza ekuvimbeleni izinhlayiya ze-zirconia.Ngesikhathi senqubo yokupholisa kusukela ekushiseni okushisayo, izinhlamvu ze-tetragonal zirconia zingangena ukuguqulwa kwesigaba kusukela esigabeni se-tetragonal kuya esigabeni se-monoclinic.Kulo mongo, i-alumina isebenza ukugcina okusanhlamvu kwe-zirconia esimweni esine-metastable, ukuvimbela ukuguqulwa okuphelele kwesigaba se-monoclinic.Lokhu kulondolozwa kwesigaba se-tetragonal kunomthelela ekuthuthukisweni okubonwayo ebukhuni bezinto zobumba
