Alumina ceramics muaj kev tiv thaiv kev hnav siab, feem ntau yog vim lawv cov qauv microstructure thiab cov khoom siv tshuaj lom neeg tshwj xeeb.
Ua ntej tshaj plaws, cov qauv me me ntawm alumina ceramics yog cov qauv polycrystalline uas muaj cov khoom me me thiab cov hlwb, uas ua rau nws muaj lub zog siab. Qhov thib ob, alumina ceramics yog cov khoom siv tawv heev, nws qhov tawv zoo ib yam li pob zeb diamond, nyuaj rau hnav, yog li nws muaj kev tiv thaiv abrasive siab. Qhov thib peb, cov khoom siv tshuaj lom neeg ntawm alumina ceramics ruaj khov heev, yuav luag tiv taus kev yaig ntawm txhua cov kua qaub, cov hauv paus thiab cov ntsev thiab lwm yam tshuaj lom neeg, thiab yuav luag tsis cuam tshuam los ntawm txhua yam kev xeb tshuaj lom neeg.
Alumina ceramics muaj ntau qib purity, thiab cov ntsiab lus ntawm Al2O3 ntau dua hauv cov alumina ceramics uas muaj purity ntau dua. Feem ntau, cov ntsiab lus aluminium ntau dua, nws qhov kev tiv thaiv kev hnav zoo dua.
Tsis tas li ntawd,alumina ceramicskuj muaj kev ruaj khov thermal zoo heev, tuaj yeem tswj tau qhov ua tau zoo heev ntawm qhov kub siab, uas ua rau nws tuaj yeem ua tau zoo heev hauv ntau yam kev ua haujlwm hnav-resistant.
Yog li ntawd, cov yam ntxwv ntawm alumina ceramics ua rau lawv ua tau zoo hauv ntau qhov chaw uas xav tau kev tiv thaiv kev hnav.
