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--Palo e pharalletseng ea Ts'ebeliso

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 insulation ea maqhubu a holimo e ntle.

2 - Li-ceramics tsa Alumina li na le ho hanyetsa mocheso, li-coefficient tse nyane tsa 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 Alumina tse phahameng ka ho fetisisa, ho thatafala le corundum ka mokhoa o ts'oanang, li ka fihla boima ba Mohs 9, ho hanyetsa ha eona ho ka tsamaisana le li-alloys tse thata haholo.
