Ibisobanuro Bigufi

Fuse Alumina - Zirconia ikorerwa mubushyuhe bwo hejuru bw'amashanyarazi arc itanura zirconium quartz umucanga na alumina.Irangwa nuburyo bukomeye kandi bwuzuye, gukomera gukomeye, guhagarara neza kwubushyuhe.Birakwiye gukora ibiziga binini byo gusya kugirango bikoreshwe ibyuma hamwe no gusya, ibikoresho bisize hamwe no guturika amabuye, nibindi.

Irakoreshwa kandi nk'inyongeramusaruro ikomeza guta inganda.Bitewe no gukomera kwayo birakoreshwa mugutanga imbaraga za Mechanical muri izi nganda.

Inzira yumusaruro no kuyishyira mubikorwa

Alumina Fused - Zirconia ikorerwa mubushyuhe bwo hejuru bwamashanyarazi arc itanura zirconium quartz umucanga na alumina.Irangwa nuburyo bukomeye kandi bwuzuye, gukomera gukomeye, guhagarara neza kwubushyuhe.Birakwiye gukora ibiziga binini byo gusya kugirango bikoreshwe ibyuma hamwe no gusya, ibikoresho bisize hamwe no guturika amabuye, nibindi.

Irakoreshwa kandi nk'inyongeramusaruro ikomeza guta inganda.Bitewe no gukomera kwayo birakoreshwa mugutanga imbaraga za Mechanical muri izi nganda.

Yttria-Tetragonal Zirconia Polycrystal (Y-TZP) na Alumina (Al2O3) bashishikajwe cyane nubuhanga bwibikoresho byatewe bitewe nuburyo bwiza bwo guhuza imitungo, nko gukomera cyane, gukomera kuvunika, n'imbaraga nyinshi no gukomera ， Ibyo biranga byatumye bakora ibikoresho bishimishije kumurongo mugari wa porogaramu ikubiyemo urwego rwa biomedical aho rwakunze gukoreshwa mugukoresha amenyo nka prothèque yatewe, abiraro, inkingi zumuzi, hamwe nikamba rya ceramic.Uretse ibyo, zikoreshwa kandi mubikorwa bitandukanye byubuhanga birimo sensor ya ogisijeni, gutwika amashyuza yumuriro, ibikoresho byo gukata, guhuza fibre optique, hamwe na selile ikomeye ya oxyde.Birakwiye ko tumenya ko iterambere ryimiterere ya Y-TZP ryatewe nubunini bwaryo bwiza hamwe na tetragonal kugirango ihindure icyiciro cya monoclinic.Ihinduka ryicyiciro riherekezwa no kwiyongera kwijwi rya 3-5% bikaviramo guhagarika ikwirakwizwa bityo bikazamura ubukana bwibintu.Ariko, ni ngombwa kumenya ko iri hinduka rishobora no kubaho ubwabyo mubihe bimwe.Niba zirconi ihuye nubushyuhe buke mubidukikije bitose biri hagati ya 100 ℃ na 300 ℃, ibyo bikaba bishobora gutuma zirconi yangirika, bikaviramo gukomera na microcracking.Iyi phenomenon izwi nka hydrothermal gusaza cyangwa Ubushyuhe buke (LTD) kandi byagaragaye nkimpamvu igira uruhare mukugabanya imikorere yibice bya zirconi mubikorwa bya orthopedic

Abashakashatsi bakoze ibintu byinshi aho alumina yinjizwa mu miterere ya zirconiya.Intego yuru ruganda ni ukongera imbaraga za LTD no gukoresha ibiranga bidasanzwe biranga ayo mafumbire kugirango tunonosore imiterere yubukorikori bwa matrise ya tetragonal zirconia Kurundi ruhande, kuba alumina muri matrix bigira uruhare runini mugushinga a imiterere ikomeye ifasha kugabanya ibice bya zirconi.Mugihe cyo gukonjesha kuva ubushyuhe bukabije, ibinyampeke bya tetragonal zirconia birashobora guhinduka mugice cya tetragonal ikagera kuri monoclinic.Ni muri urwo rwego, alumina ikora kugirango ibungabunge ibinyampeke bya zirconi mu buryo bworoshye, birinda impinduka zuzuye mu cyiciro cya monoclinic.Uku kubungabunga icyiciro cya tetragonal bigira uruhare mugutezimbere kugaragara mubukomere bwibikoresho bya ceramic
