Ha ho tluoa tabeng ea silicon carbide ceramics, ho na le mefuta e 'meli e meholo:karabelo bonded silicon carbidele sintered silicon carbide. Le hoja mefuta e 'meli ea li-ceramics e fana ka maemo a phahameng a ho tšoarella le ho hanyetsa ho apara, ho na le phapang e kholo pakeng tsa tse peli.
Ha re qaleng ka lirafshoa tse kopantsoeng tsa silicon carbide ceramics. Li-ceramics tsena li pakeng tsa 85% le 90% silicon carbide 'me li na le silicon e itseng. Boemo ba bona ba mocheso bo phahameng ke 1380 ° C. E 'ngoe ea melemo ea mantlha ea lirafshoa tsa silicon carbide ceramics ke hore li ka hlophisoa ka boholo le libopeho tse kholo. Sena se etsa hore e be lisebelisoa tse loketseng bakeng sa ho theha lihlahisoa tse ikhethang le tsa setsebi. Ho feta moo, coefficient e tlase ea katoloso le khanyetso e ntle ea ho roala ha li-ceramics li li etsa khetho e tsebahalang indastering ea leholiotsoana la meepo.
Sintered sintered silicon carbide e na le lintho tse phahameng tsa silicon carbide, tse ka fihlang ho feta 99%, 'me mocheso o phahameng ka ho fetisisa oa ho hanyetsa ke 1650 ° C. Karolo e itseng ea katoloso e hlahisoa nakong ea ts'ebetso ea sintering, e etsang hore SiC e se nang khatello e be e loketseng ho etsa likarolo tsa SiC tse nepahetseng. Ka lebaka la ho nepahala ha eona ho phahameng, silicon carbide e se nang khatello e atisa ho sebelisoa ho etsa hlobo le likarolo tse nepahetseng tse sa senyeheng.
Ntle le liforomo tse nepahetseng le likarolo tsa ho roala, lisebelisoa tsa sebōpi tse phahameng tsa indasteri ea lik'hemik'hale li ka nka monyetla oa ho hanyetsa mocheso o phahameng oa sintered silicon carbide. Bakeng sa ba batlang li-tubes tsa mocheso o sebetsang hantle bakeng sa lisebelisoa tsa bona tsa ho sebetsa ka lik'hemik'hale, silicon carbide e se nang khatello ke khetho e sebetsang ea thepa.
Ka kakaretso, bonding ba karabelo le sintering e se nang khatello ea li-ceramics tsa SiC, leha e 'ngoe le e' ngoe e na le melemo le mefokolo ea eona, e loketse liindasteri le lits'ebetso tse fapaneng. Haeba o hloka sehlahisoa se ikhethileng kapa se seholoanyane se ka mamellang ho roala, li-ceramics tsa silicon carbide ceramics e ka ba khetho e nepahetseng bakeng sa hau. Bakeng sa likarolo tse thata tse hlokang ho mamella mocheso o phahameng, silicon carbide e se nang khatello e ka ba khetho e ntle. Ho sa tsotellehe hore na u khetha mofuta ofe oa silicon carbide ceramic, u ka kholiseha hore e tla fana ka nako e telele le e tsitsitseng eo morero oa hau o e hlokang.
