I-Magnesia-stabilized zirconia (MSZ) inokomelela ngakumbi kukhukuliseko kunye nokuphazamiseka kwe-thermal. Ukunyuka kwesigaba esincinci se-tetragonal kuphuhla ngaphakathi kwi-cubic phase grains of transformation-toughened zirconias ezifana ne-magnesium-stabilized zirconia. Xa i-fracture izama ukuhamba kwizinto eziphathekayo, ezi zitshintshi zitshintsha ukusuka kwisigaba se-tetragonal se-meta-stable ukuya kwisigaba esizinzile se-monoclinic. Imvula iyanda ngenxa yoko, iphazamisa indawo yokuphuka kunye nokwandisa ukuqina. Ngenxa yeeyantlukwano kwindlela izinto ekrwada ezilungiswe ngayo, i-MSZ inokuba yindlovu okanye tyheli-orenji ngombala. I-MSZ, enombala wophondo lwendlovu, icocekile kwaye ineempawu ezibalaseleyo. Kubushushu obuphezulu (220°C nangaphezulu) kunye nezicwangciso zokufuma eziphezulu, i-MSZ izinzile kune-YTZP, kwaye i-YTZP idla ngokuthotywa. Ngaphandle koko, i-MSZ ine-conductivity ephantsi ye-thermal kunye ne-CTE efana nentsimbi, ukuthintela ukungahambi kakuhle kwe-thermal kwiinkqubo ze-ceramic-to-metal.

Usetyenziso

I-Magnesia-zirconia ezinzileyo ingasetyenziswa kwiivalvu, iimpompo, kunye neegaskets kuba inxibe kakuhle kunye nokumelana nomhlwa. Ikwayinto ekhethwayo kumacandelo epetrochemical and chemical processing. I-Zirconia ceramics lukhetho olukhulu kumacandelo amaninzi, kubandakanya:

• Iiseramics zesakhiwo

• Iibheringi

• Nxiba amalungu

• Nxiba imikhono

• Imilomo yokutshiza

• Impompo imikhono

• Iipiston zokutshiza

• Izihlahla

• Amalungu eseli ye-oksidi eqinile

• izixhobo ze-MWD

• Izikhokelo ze-roller yokwenza ityhubhu

• Ngokunzulu kakuhle, iindawo ezisezantsi

IMagnesia-Stabilized Zirconia Machining

Kwiindawo eziluhlaza, iibhiskithi, okanye iindawo ezixinene ngokupheleleyo, iMSZ inokwenziwa ngoomatshini. Xa iluhlaza okanye ikwimo yebhiskithi, inokwenziwa ngoomatshini bejometri entsonkothileyo ngokulula. Umzimba we-zirconia uyancipha malunga ne-20% ngexesha lenkqubo ye-sintering, okuyimfuneko ukuxinanisa ngokwaneleyo izinto eziphathekayo. Ngenxa yoku kucutheka, i-zirconia pre-sintering ayikwazi ukwenziwa ngoomatshini ngokunyamezela okuhle kakhulu. Isixhobo esonakele ngokupheleleyo kufuneka senziwe ngoomatshini okanye siphuculwe ngezixhobo zedayimani ukuze sifumane ukunyamezelana okuqinileyo. Kobu buchule bokwenza, imathiriyeli iyacolwa ngokusebenzisa isixhobo esihle kakhulu esiqatywe ngedayimane okanye ivili de ifomu efunekayo ifumaneke. Oku kunokuba yinkqubo echitha ixesha kwaye ibiza kakhulu ngenxa yobunzima bendalo kunye nokuqina.
