- Tlhahisoleseding ea Motheo ka Alumina Ceramics le Silicon Carbide Ceramics
Alumina ceramic ke thepa ea ceramic e entsoeng haholo ka aluminium oxide (Al2O3), e khetholloang ka matla a phahameng, ho thatafala, ho hanyetsa, le ho hanyetsa ho bola ha asiti le alkali. Ka lebaka la thepa ea eona e ntle haholo, alumina ceramic e sebelisoa haholo masimong a joalo ka mechini, lisebelisoa tsa elektroniki le boenjiniere ba lik'hemik'hale.
Silicon carbide ceramic ke thepa ea ceramic e entsoeng ka silicon carbide (SiC), eo hape e leng-masebelisoa a phahameng a sebetsang a ceramic. Ntle le ho bonts'a boima bo phahameng, matla le ho hanyetsa ho roala, silicon carbide ceramic e na le botsitso bo botle ba mocheso le botsitso ba lik'hemik'hale. Sena se e nolofalletsa ho boloka botsitso ba ts'ebetso ea eona tlas'a maemo a thata joalo ka mocheso o phahameng, khatello e phahameng le kutu e matla.
- Papiso ea Ts'ebetso ea Lik'hemik'hale
1. Thata le Matla: Ka bobeli alumina ceramics le silicon carbide ceramics li bontša ho thatafala ho phahameng le matla. Leha ho le joalo, li-ceramics tsa silicon carbide ka kakaretso li na le boima bo phahameng ho feta lirafshoa tsa alumina, e leng se etsang hore li se ke tsa betla le ho hoa.
2. Apara Resistance: Ka lebaka la boima bo phahameng ba silicon carbide ceramics, ho hanyetsa ha bona ho batla ho le matla. Ka tlas'a-o sebetsa ka lebelo le phahameng kapa{3}}maemo a boima a{3}moroalo, khanyetso ea silicon carbide ceramics e sebetsa hantle haholo, e etsa hore e tšoanelehe bakeng sa likarolo tsa tlhahiso tse hlokang ho se mamelle haholo.
3. Botsitso ba Lik'hemik'hale: Ka bobeli li-alumina ceramics le silicon carbide ceramics li bonts'a botsitso bo botle ba lik'hemik'hale, ho hanyetsa kutu ho tsoa lik'hemik'hale tse ngata. Leha ho le joalo, libakeng tse itseng tsa lik'hemik'hale, li-ceramics tsa silicon carbide li ka bonts'a khanyetso e phahameng ea kutu.
- Libaka tsa Kopo
1. Lisebelisoa tsa Aluminium Oxide Ceramics: Ka lebaka la matla a eona a phahameng, boima bo phahameng, le ho hanyetsa ka mokhoa o babatsehang oa ho apara, li-ceramics tsa aluminium oxide li sebelisoa haholo ha ho etsoa likarolo tsa mechine, li-abrasives, lisebelisoa tsa ho itšeha, hammoho le li-substrates le lisebelisoa tsa encapsulation bakeng sa lisebelisoa tsa elektronike. Ho feta moo, lirafshoa tsa aluminium oxide li bapala karolo ea bohlokoa masimong a kang boenjiniere ba lik'hemik'hale, peterole le metallurgy.
2. Lisebelisoa tsa Silicon Carbide Ceramics: Ho thatafala ho hoholo, matla, botsitso ba mocheso, le botsitso ba lik'hemik'hale tsa lirafshoa tsa silicon carbide li li etsa khetho e nepahetseng bakeng sa ho etsa{1}}lisebelisoa tse phahameng tsa mocheso, libering, liqibi le likarolo tse ling. Likarolong tse kang sefofane, tlhahiso ea likoloi, le matla a macha, lirafshoa tsa silicon carbide li na le menyetla e mengata ea kopo.
- Qetello
Ka kakaretso, lirafshoa tsa alumina le lirafshoa tsa silicon carbide li sebetsa-lisebelisoa tse phahameng tsa ts'ebetso, 'me e 'ngoe le e 'ngoe e na le melemo e ikhethang mafapheng a fapaneng a ts'ebeliso. Mabapi le ho hanyetsa ho roala, li-ceramics tsa silicon carbide li bonts'a ts'ebetso e phahameng ka lebaka la boima ba tsona bo phahameng. Leha ho le joalo, lits'ebetsong tse sebetsang, khetho ea thepa ea ceramic e tlameha ho hlahlojoa ka botlalo ho ipapisitse le maemo le litlhoko tse ikhethang tsa ts'ebeliso. Le ha li-ceramics tsa alumina li kopana le litlhoko tse itseng tsa ho hanyetsa, li fana ka thepa e ntle haholo ea ho kenya motlakase le tahlehelo e tlase ea dielectric, e leng se etsang hore li sebelisoe haholo lisebelisoa tsa motlakase le li-substrates tsa elektroniki. Ka lehlakoreng le leng, li-ceramics tsa silicon carbide li loketse maemo a thata joalo ka mocheso o phahameng, khatello e phahameng le lebelo le holimo, ho fumana lits'ebetso sebakeng sa sefofane, tlhahiso ea likoloi le likarolo tse ling.
Alumina ceramics le silicon carbide ceramics e 'ngoe le e' ngoe e na le litšobotsi le melemo ea eona. Re lokela ho khetha thepa ea ceramic e loketseng ka ho fetisisa ho latela litlhoko tse khethehileng tsa kopo.
- Tecera e na le lilemo tse 25 tsa boiphihlelo ba tlhahiso, ebang ke alumina kapa silicon carbide ceramics. Haeba u na le litlhoko, ka kopo ikopanye le rona
