White Zirconia ZrO2 Ceramic Shafts Lishafi tse khannoang
Kenyelletso ea Sehlahisoa
Zirconia e na le ho thatafala ho hoholo le ho tiea, ho hanyetsa ho roala, 'me e na le motlakase o motle oa motlakase le ho hanyetsa lik'hemik'hale hape. Ke thepa e matla, e tšoarellang, e tiileng, thepa e sebelisoa bakeng sa karolo e sa tsitsang le likarolo tsa mochini. Thermal conductivity ea thepa ea zirconia e tlase haholo (3w / m ・ K), kahoo E sebelisoa bakeng sa insulator ea mocheso hape.
Zirconia e tsitsitseng ea Yttria e fana ka melemo e kang ho eketsa bophelo ba shaft ka ho fokotsa ho senya, ho fokotseha ho hoholo ha lerata (maemong a mangata), tumello ea USDA bakeng sa ho kopana le lihlahisoa tsa lijo. Haeba theko e sa amehe, yttria-stabilized zirconia ke khetho e ntle ea thepa ho feta alumina ceramics.
Li-bearings tsa ceramic tsa zirconia le li-shafts tse thata ka ho fetisisa li apara ka tlase haholo 'me li tšoarella nako e telele ho feta li-bearings tsa tšepe.
Qetello e hlahelletseng ea bokaholimo - Bokhopo ba lirafshoa tsa alumina hangata ha bo fete 0.15um, bo boreleli haholo ho feta libere tsa alumina ceramic. Ha li-bearings li le boreleli, khohlano e fokotseha, 'me e sebetsa hantle haholoanyane.
Insulator e seng ea makenete le ea motlakase - Haeba ho na le litlhoko tse thata tikolohong e sa sebetseng ea makenete, li-ceramic bearings li loketse ho feta libere tsa tšepe.
Lintho tse khahlang joalo ka matla a ho hatella le a flexural, ho tiea ha fracture.
Ho hanyetsa kutu e ntle haholo - Li-ceramics tsa zirconia ha li na kutu 'me li ke ke tsa holisoa joalo ka libering tsa tšepe maemong a alkali kapa acid.
