Polycrystalline Al2O3 alumina ceramics e etselitsoeng ho hanyetsa mocheso o phahameng
Ts'ebetso ea aluminium oxide ceramics
1--Bothata bo phahameng
Rockwell hardness ea alumina ceramics ke HRA80-90, ea bobeli ho daemane ka thatafala, e feta hole ho feta tšepe e sa senyeheng le tšepe e sa hloekang.
2--Hantle ho Wear Resistance
Ho hanyetsa ho roala ha lirafshoa tsa alumina ho lekana le linako tse 266 tsa tšepe ea manganese le linako tse 171.5 tsa tšepe e phahameng ea chromium. Tlas'a maemo a ts'oanang a ts'ebetso, e ka eketsa bophelo ba tšebeletso ea lisebelisoa bonyane ka makhetlo a leshome.
3-- Boima ba Leseli
Boima ba li-ceramics tsa alumina ke 3.7 ~ 3.95g / cm °, e leng halofo feela ea tšepe le tšepe, 'me e ka fokotsa haholo mojaro oa thepa.
4-- Phatlalatso e Pharalletseng ea Tšebeliso
Li-ceramics tsa aluminium li sebelisoa haholo mecheng, li-fiber optics, lisebelisoa tsa ho itšeha, bongaka, lijo, lik'hemik'hale, sefofane le masimo a mang.
Melemo ea lisebelisoa tsa alumina ceramics:
1 - Li-ceramics tsa aluminium li na le thepa e ntle haholo ea ho itšireletsa. Tahlehelo ea maqhubu a holimo e batla e le nyane, 'me ho koala maqhubu a phahameng ho lokile.
2-Alumina ceramics e na le ho hanyetsa mocheso, coefficient e nyane ea katoloso ea mocheso, matla a phahameng a mochini le conductivity e ntle ea mocheso.
3-- Alumina ceramics e na le khanyetso ea lik'hemik'hale le tšepe e qhibilihisitsoeng.
4-- Alumina ceramics ha e chese, ha e bonolo ho mafome ebile e matla ebile ha e bonolo ho senya, ka lisebelisoa tse ling tsa manyolo le lisebelisoa tsa tšepe li ke ke tsa bapisoa le boleng bo botle haholo.
5 - Li-ceramics tsa aluminium tse phahameng ka ho fetisisa, ho thatafala le corundum ka mokhoa o ts'oanang, li ka fihla boima ba Mohs 9, khanyetso ea eona ea ho roala e ka tsamaisana le li-alloys tse thata haholo.
