Carbide ea silicon e sintered ke thepa ea bohlokoa ea ceramic, e sebelisoang haholo maemong a mocheso o phahameng, khatello e phahameng le matla a phahameng. Ho sintering ha SIC ka mokhoa o arabelang ke mohato oa bohlokoa ho lokiseng thepa ea SIC e sintered. Taolo e ntle ka ho fetisisa ea karabelo ea SIC e sintered e ka re thusa ho laola boemo ba karabelo le ho ntlafatsa boleng ba sehlahisoa. Mokhoa o motle ka ho fetisisa oa taolo ea karabelo ea silicon e sintered o tšohloa pampiring ena.
1. Ntlafatso ea maemo a SIC a sintering reaction
Maemo a karabelo ke diparamente tsa bohlokwa tsa karabelo ya sintered silicon carbide, ho kenyeletswa mocheso wa karabelo, kgatello ya karabelo, karolelano ya boima ba reactant le nako ya karabelo. Ha ho ntlafatswa maemo a karabelo, ho hlokahala ho fetola ho ya ka ditlhoko tse ikgethang tsa kopo le mokgwa wa karabelo.
(1) Mocheso oa karabelo: Mocheso oa karabelo ke e 'ngoe ea lintlha tsa bohlokoa tse amang lebelo la karabelo le boleng ba sehlahisoa. Sebakeng se itseng, ha mocheso oa karabelo o phahame, lebelo la karabelo le potlaka, boleng ba sehlahisoa boa phahama. Leha ho le joalo, mocheso o phahameng haholo oa karabelo o tla lebisa keketseho ea masoba le mapetsong sehlahisoa, e leng se amang boleng ba sehlahisoa.
(2) Khatello ea karabelo: Khatello ea karabelo le eona e na le tšusumetso lebelong la karabelo le bongata ba sehlahisoa. Ka har'a sebaka se itseng, ha khatello ea karabelo e phahame, lebelo la karabelo le eketseha 'me bongata ba sehlahisoa bo phahame. Leha ho le joalo, khatello e phahameng haholo ea karabelo le eona e ka lebisa masobeng le mapetsong a mangata sehlahisoa.
(3) karolelano ea boima ba reactant: karolelano ea boima ba reactant ke ntlha e 'ngoe ea bohlokoa e amang lebelo la karabelo le boleng ba sehlahisoa. Ha karolelano ea boima ba carbon ho silicon e loketse, sekhahla sa karabelo le boima ba sehlahisoa. Haeba karolelano ea boima ba reactant e sa lokela, e tla ama sekhahla sa karabelo le boima ba sehlahisoa.
(4) Nako ea karabelo: Nako ea karabelo ke e 'ngoe ea mabaka a amang lebelo la karabelo le boleng ba sehlahisoa. Ka har'a sebaka se itseng, ha nako ea karabelo e le telele, lebelo la karabelo le lieha 'me boleng ba sehlahisoa bo phahame. Leha ho le joalo, nako e telele haholo ea karabelo e tla lebisa keketseho ea masoba le mapetsong sehlahisoa, e leng se amang boleng ba sehlahisoa.
2. Taolo ea ts'ebetso ea carbide ea silicon e sebetsang hantle
Mokhoeng oa ho sila karabelo ea SIC, ho hlokahala ho laola mokhoa oa karabelo. Sepheo sa taolo ke ho netefatsa botsitso ba karabelo le ho tsitsa ha boleng ba sehlahisoa. Taolo ea ts'ebetso ea karabelo e kenyelletsa taolo ea mocheso, taolo ea khatello, taolo ea sepakapaka le taolo ea boleng ba reactant.
(1) Taolo ea mocheso: Taolo ea mocheso ke e 'ngoe ea likarolo tsa bohlokoa tsa taolo ea ts'ebetso ea karabelo. Taolo ea mocheso Mocheso oa karabelo o lokela ho laoloa ka nepo kamoo ho ka khonehang ho netefatsa botsitso ba ts'ebetso ea karabelo le boleng bo tsitsitseng ba sehlahisoa. Tlhahisong ea sejoale-joale, sistimi ea taolo ea khomphutha hangata e sebelisoa ho laola mocheso oa karabelo ka nepo.
(2) Taolo ea khatello: Taolo ea khatello ke karolo e 'ngoe ea bohlokoa ea taolo ea ts'ebetso ea karabelo. Ka ho laola khatello ea karabelo, botsitso ba ts'ebetso ea karabelo le ho tsitsa ha boleng ba sehlahisoa li ka netefatsoa. Tlhahisong ea sejoale-joale, sistimi ea taolo ea khomphutha hangata e sebelisoa ho laola khatello ea karabelo ka nepo.
(3) Taolo ea sepakapaka: Taolo ea sepakapaka e bolela tšebeliso ea sepakapaka se itseng (joalo ka sepakapaka se sa sebetseng) ts'ebetsong ea karabelo ho laola ts'ebetso ea karabelo. Ka ho laola sepakapaka, botsitso ba ts'ebetso ea karabelo le ho tsitsa ha boleng ba sehlahisoa li ka netefatsoa. Tlhahisong ea sejoale-joale, sistimi ea taolo ea khomphutha hangata e sebelisoa ho laola sepakapaka.
(4) Taolo ea boleng ba Reactant: Taolo ea boleng ba Reactant ke e 'ngoe ea lintlha tsa bohlokoa ho netefatsa botsitso ba ts'ebetso ea karabelo le botsitso ba boleng ba sehlahisoa. Ka ho laola boleng ba li-reactant, botsitso ba ts'ebetso ea karabelo le botsitso ba boleng ba sehlahisoa bo ka netefatsoa. Tlhahisong ea sejoale-joale, sistimi ea taolo ea khomphutha hangata e sebelisoa ho laola boleng ba li-reactant.
Taolo e ntle ka ho fetisisa ea SIC e sintering e arabelang ke mohato oa bohlokoa oa ho lokisa lisebelisoa tsa SIC tse sintered tsa boleng bo holimo. Ka ho ntlafatsa maemo a karabelo, ho laola ts'ebetso ea karabelo le ho beha leihlo lihlahisoa tsa karabelo, botsitso ba ts'ebetso ea karabelo le ho tsitsa ha boleng ba sehlahisoa li ka netefatsoa. Ts'ebelisong e sebetsang, karabelo ea carbide ea silicon e sintered e hloka ho fetoloa ho latela maemo a itseng a ts'ebeliso ho fihlela litlhoko tse fapaneng tsa ts'ebeliso.
