Melemo e tšeletseng ea khabide ea silicon e sintered e nang le khatello ea sepakapaka le ts'ebeliso ea li-ceramic tsa silicon carbide

Carbide ea silicon e sintered e nang le khatello ea sepakapaka ha e sa sebelisoa feela e le ntho e khorofolang, empa e sebelisoa haholo e le thepa e ncha, 'me e sebelisoa haholo lihlahisoa tsa theknoloji e phahameng, tse kang liseramike tse entsoeng ka thepa ea silicon carbide. Joale melemo e tšeletseng ea silicon carbide e sintering ea khatello ea sepakapaka le ts'ebeliso ea liseramike tsa silicon carbide ke efe?

Melemo e tšeletseng ea thepa ea silicon carbide e sintered khatello ea sepakapaka:

1. Boima bo tlase

Thepa ea silicon carbide e na le boima bo tlase ho feta tšepe, e leng se etsang hore sesebelisoa se be bobebe.

2. Khanyetso ea ts'enyeho

Thepa ea silicon carbide e na le ntlha e phahameng ea ho qhibiliha, ho se sebetse hantle ha lik'hemik'hale, ho hanyetsa ho thothomela ha mocheso, silicon carbide e sebelisoa linthong tse senyang, li-oven tsa ceramic, li-blanks tsa silicon carbide, e ka sebelisoa indastering ea ho qhibilihisa le ho qhibilihisa ka setofo sa silindara se otlolohileng, setene, lesela la sele ea aluminium electrolytic, tungsten, setofo se senyenyane le lihlahisoa tse ling tsa silicon carbide tsa ceramic.

3, mocheso o phahameng, coefficient ea katoloso ea mocheso e fokotsehile

Thepa ea silicon carbide e etsoa mochesong o phahameng. Libakeng tse ling tsa mocheso o phahameng, thepa e hlokang matla a ts'ebetso le ho nepahala ha ts'ebetso eo li-ceramics tsa silicon carbide li ka e fihlelang ea hlokahala. Mocheso o phahameng oa silicon carbide ke hoo e ka bang 800, 'me mocheso oa tšepe ke 250 feela. Palo e boima, karolelano ea katoloso ea mocheso ea silicon carbide e pakeng tsa 25 ~ 1400 ke 4.10-6 /C. Coefficient ea katoloso ea mocheso ea silicon carbide ea lekanngoa, 'me liphetho li bontša hore bongata bo bonyenyane haholo ho feta ba lintho tse ling tse senyang le thepa ea mocheso o phahameng. Carbide ea silicon e sintered tlas'a khatello ea sepakapaka

4, conductivity e phahameng ea mocheso

Ho tsamaisa mocheso ha thepa ea silicon carbide ho phahame, e leng tšobotsi e 'ngoe ea bohlokoa ea thepa ea 'mele ea silicon carbide. Ho tsamaisa mocheso ha silicon carbide ho hoholo haholo ho feta ha lintho tse ling tse sa sebetseng hantle le tse sa sebetseng hantle, hoo e ka bang makhetlo a 4 ho feta corundum. Silicon carbide e na le coefficient e tlase ea katoloso ea mocheso le ho tsamaisa mocheso ho phahameng, kahoo mosebetsi o tla ba tlas'a khatello e fokolang ea mocheso nakong ea ho futhumatsa le ho pholisa. Ke ka lebaka leo likarolo tsa SiC li hanelang haholo ho tšoaroa ke shock.

5, matla a phahameng a mechini, ho satalla hantle

Matla a mechini a thepa ea silicon carbide a phahame haholo, a thibela ho fetoha ha thepa. Silicon carbide e na le matla a mechini a phahameng ho feta corundum.

6, ho thatafala ho hoholo le ho hanyetsa ho tsofala

Bothata ba thepa ea silicon carbide bo phahame haholo, 'me boima ba sekheo sa Moss ke 9.2 ~ 9.6, bo latela daemane le tungsten carbide feela. Ha e bapisoa le thepa ea tšepe ea tšepe, e fana ka boima bo phahameng, coefficient e tlase ea khohlano, khohlano e tlase haholo, ho ba thata ha bokaholimo le ho hanyetsa ho tsofala hantle ntle le ho tlotsa. Ho feta moo, e hanela lintho tse kantle, e ntlafatsa mamello ea bokaholimo. Carbide ea silicon e sintered tlas'a khatello ea sepakapaka

Tšebeliso ea li-ceramic tsa silicon carbide tse nang le khatello ea sepakapaka

1, tlhahiso ea lintho tse khethehileng tsa silicon carbide tsa letsopa

Thepa ea silicon carbide ke thepa e nang le bothata bo phahameng le litšenyehelo tse tlase, e ka hlahisang lihlahisoa tsa silicon carbide, tse kang litiiso tsa silicon carbide, matsoho a silicon carbide, lipoleiti tse thibelang likulo tsa silicon carbide, liprofaele tsa silicon carbide, jj., tse ka sebelisoang ho litiiso tsa mechini le lipompong tse fapaneng. Carbide ea silicon e sintered tlas'a khatello ea sepakapaka

2, tlhahiso ea lintho tse bonahalang tsa zirconia tsa letsopa le khethehileng

Ceramic ea Zirconia e na le conductivity e phahameng ea ionic, botsitso bo botle ba lik'hemik'hale le botsitso ba sebopeho, 'me e fetohile thepa ea electrolyte e ithutoang haholo le e sebelisoang. Ka ho ntlafatsa ts'ebetso ea tlhahiso ea filimi ea electrolyte e thehiloeng ho zirconia, ho fokotsa mocheso oa ts'ebetso le litšenyehelo tsa tlhahiso ea thepa ena, le ho loanela ho fihlela indasteri le hona ke tataiso ea bohlokoa ea lipatlisiso tsa nakong e tlang.
