Feem ntau siab alumina cib, lub thermal shock stability thiab spalling kuj tsis zoo, tus naj npawb ntawm thermal shock stability feem ntau ntawm xya zaus.
Taw qhia ntawm ZrO2 rau hauv dav dav siab alumina cib tsim tshuab,thaumsib tovUa ntej sib tov cov zirconium mullite hmoov thiab bauxite hmoov sib npaug, nyob rau hauv txoj kev no, ua rau lub siab alumina cib matrix ib feem los txhim kho lub toughness.Tam sim no, los ntawm kev siv qhov sib txawv coefficient ntawm expansion ntawm Al2O3 thiab ZrO2 tsim me me tawg, tiv taus. lub thermal stress, yog li, zoo heev txhim kho lub thermalpoob siab stability thiab spalling kuj.Nws tus naj npawb ntawm thermal poob siab stability yog ntau tshaj 17 lub sij hawm, zoo txhim kho lub thermal shock stability, tiv thaiv vim qhov kub thiab txias hloov sai.
Spalling siab alumina cib vim nws cov kev ua tau zoo tshaj plaws nyob rau hauv dav dav siab alumina cib, feem ntau siv rau cement rotary kiln, txiv qaub kiln, kiln tsheb thiab kiln rooj tog, thiab lwm yam, tau txais cov txiaj ntsig zoo.
