Li-ceramics tsa alumina tsa polycrystalline Al2O3 tse etselitsoeng ho hanyetsa mocheso o phahameng ka mokhoa o ikhethileng

Tshebetso ea li-ceramics tsa aluminium oxide

1--Bothata bo phahameng

Thatafalo ea Rockwell ea liserami tsa alumina ke HRA80-90, e latelang daemane feela ka thatafalo, e fetang hole tšepe e sa tsofaleng le ho hanyetsa ho robeha ha tšepe e sa hloekang.

2--Khanyetso e Ntle ea ho Tloha

Ho hanyetsa ho tsofala ha liserami tsa alumina ho lekana le tšepe ea manganese ka makhetlo a 266 le tšepe e nang le chromium e ngata ka makhetlo a 171.5. Tlas'a maemo a tšoanang a ts'ebetso, e ka eketsa bophelo ba ts'ebeletso ea lisebelisoa bonyane ka makhetlo a leshome.

3--Boima bo bobebe

Botenya ba liserami tsa alumina ke 3.7 ~ 3.95g/cm°, e leng halofo feela ea tšepe le tšepe, 'me e ka fokotsa mojaro oa lisebelisoa haholo.

4--Sebaka se Seholo sa Ts'ebeliso

Li-ceramic tsa alumina li sebelisoa haholo mechineng, fiber optics, lisebelisoa tsa ho seha, tsa bongaka, tsa lijo, tsa lik'hemik'hale, tsa lifofane le masimong a mang.

Melemo ea li-ceramic tsa alumina:

1--Liserame tsa Alumina li na le thepa e ntle ea ho thibela ho ruruha. Tahlehelo ea maqhubu a phahameng e nyane haholo, 'me ho thibela ho ruruha ha maqhubu a phahameng ho molemo.

2--Liserame tsa Alumina li na le ho hanyetsa mocheso, coefficient e nyane ea katoloso ea mocheso, matla a phahameng a mechini le conductivity e ntle ea mocheso.

3--Liserame tsa Alumina li na le khanyetso ea lik'hemik'hale le khanyetso ea tšepe e qhibilihisitsoeng.

4--Lisepa tsa Alumina ha li chese, ha li bonolo ho rusa ebile li matla ebile ha li senyehe habonolo, hammoho le lisebelisoa tse ling tsa tlhaho le lisebelisoa tsa tšepe li ke ke tsa bapisoa le boleng bo botle.

5--Alumina ceramics e hanyetsa ho tsofala ho hoholo, ho thatafala le corundum ho tšoana, e ka fihla ho thatafalo ea Mohs 9, ho hanyetsa ha eona ho ka bapisoa le li-alloy tse thata haholo.
