Kufotokozera Kwachidule

Fused Alumina-Zirconia amapangidwa mu ng'anjo yamagetsi yotentha kwambiri pophatikiza mchenga wa zirconium quartz ndi alumina.Amadziwika ndi mawonekedwe olimba komanso owundana, kulimba kwambiri, kukhazikika kwamafuta abwino.Ndikoyenera kupanga mawilo akuluakulu opera azitsulo zopangira zitsulo ndi snagging, zida zokutira ndi kuphulika kwa miyala, etc.

Amagwiritsidwanso ntchito ngati chowonjezera mu Continuous casting refractories.Chifukwa cha kulimba kwake kwakukulu kumagwiritsidwa ntchito popereka mphamvu zamakina muzokana izi.

Njira Yopanga Ndi Kugwiritsa Ntchito

Fused Alumina--Zirconia imapangidwa mu ng'anjo yamagetsi yotentha kwambiri pophatikiza mchenga wa zirconium quartz ndi alumina.Amadziwika ndi mawonekedwe olimba komanso owundana, kulimba kwambiri, kukhazikika kwamafuta abwino.Ndikoyenera kupanga mawilo akuluakulu opera azitsulo zopangira zitsulo ndi snagging, zida zokutira ndi kuphulika kwa miyala, etc.

Amagwiritsidwanso ntchito ngati chowonjezera mu Continuous casting refractories.Chifukwa cha kulimba kwake kwakukulu kumagwiritsidwa ntchito popereka mphamvu zamakina muzokana izi.

Yttria-Tetragonal Zirconia Polycrystals (Y-TZP) ndi Alumina (Al2O3) akopa chidwi kwambiri pa matekinoloje azinthu zakuthupi chifukwa cha kuphatikiza kwawo kwakukulu kwa zinthu, monga kuuma kwakukulu, kulimba kwapang'onopang'ono, kulimba kwambiri komanso kuuma , Makhalidwe awa awapanga. zida zowoneka bwino pamagwiritsidwe osiyanasiyana okhudzana ndi zamankhwala momwe zimagwiritsidwira ntchito nthawi zambiri popanga mano monga ma prosthetic implant abutments, milatho, mizati ya mizu, ndi korona wa ceramic.Kupatula apo, amagwiritsidwanso ntchito pamakina osiyanasiyana opangira uinjiniya kuphatikiza masensa okosijeni, zokutira zotchingira matenthedwe, zida zodulira, zolumikizira ma fiber owoneka bwino, ndi ma cell olimba a oxide.Ndizofunikira kudziwa kuti kusintha kwa makina a Y-TZP kumayenderana ndi kukula kwake kwambewu ndi kusintha kwa gawo la tetragonal kupita ku monoclinic.Kusintha kwa gawoli kumayendera limodzi ndi kuchuluka kwa voliyumu pafupifupi 3-5% zomwe zimalepheretsa kufalikira kwa ming'alu motero kumawonjezera kulimba kwa zinthu.Komabe, ndikofunikira kuzindikira kuti kusinthaku kumatha kuchitikanso zokha pamikhalidwe ina.Ngati zirconia imayang'aniridwa ndi kutentha kochepa m'malo onyowa omwe ali pakati pa 100 ℃ ndi 300 ℃, zomwe zingayambitse kuwonongeka kwa zirconia, zomwe zimapangitsa kuti zikhale zovuta komanso zowonongeka.Chodabwitsa ichi chimadziwika kuti kukalamba kwa hydrothermal kapena Low-Temperature Degradation (LTD) ndipo chadziwika kuti ndi chinthu chothandizira kuchepetsa ntchito ya zirconia m'magulu a mafupa.

Ochita kafukufuku apanga ma composites angapo momwe aluminiyamu imaphatikizidwa mu zirconia.Cholinga cha kuphatikiza uku ndikupititsa patsogolo kukana kwa LTD ndikuwonjezera mawonekedwe apadera azoumbazi kuti apititse patsogolo makina a tetragonal zirconia matrix Komano, kupezeka kwa alumina mu matrix kumathandizira kwambiri popanga kapangidwe kolimba komwe kumathandizira kuletsa zirconia particles.Pakuzizira kwa kutentha kwa sintering, mbewu za tetragonal zirconia zimatha kusintha gawo kuchokera ku gawo la tetragonal kupita ku gawo la monoclinic.M'nkhaniyi, alumina amathandiza kusunga mbewu za zirconia m'malo osasunthika, kuteteza kusinthika kwathunthu ku gawo la monoclinic.Kusungidwa kwa gawo la tetragonal kumathandizira kuti pakhale kusintha kwa kuuma kwa zinthu za ceramic
