Tsis zoo li cov khoom siv ceramic ib txwm muaj uas feem ntau nyuaj thiab tawg yooj yim, Zirconia muaj lub zog siab, tiv taus kev hnav, thiab yooj ywm dua li lwm cov khoom siv ceramic. Zirconia yog cov khoom siv ceramic muaj zog heev nrog cov khoom zoo heev hauv kev tawv, tawg yooj yim, thiab tiv taus xeb; txhua yam tsis muaj cov khoom zoo tshaj plaws ntawm cov khoom siv ceramic - siab brittleness.
Muaj ntau qib ntawm Zirconia muaj, feem ntau ntawm cov uas yog Yttria Partially Stabilized Zirconia (Y-PSZ) thiab Magnesia Partially Stabilized Zirconia (Mg-PSZ). Ob qho tib si ntawm cov ntaub ntawv no muaj cov khoom zoo heev, txawm li cas los xij, qhov chaw ua haujlwm thiab qhov geometry ntawm ib feem yuav qhia tias qib twg yuav haum rau cov ntawv thov tshwj xeeb (ntau ntxiv rau qhov no hauv qab no). Nws txoj kev tiv thaiv tshwj xeeb rau kev tawg thiab kev nthuav dav thermal siab ua rau nws yog cov khoom zoo heev rau kev koom ua ke ceramics nrog cov hlau zoo li hlau. Vim yog Zirconia cov khoom tshwj xeeb nws qee zaum hu ua "ceramic steel".
Cov Khoom Siv Zirconia Dav Dav
