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 sila ha sic ka karabelo ke mohato oa bohlokoa ho lokiseng thepa ea SIC e sintered. Taolo e ntle ka ho fetisisa ea karabelo ea sintered silicon carbide e ka re thusa ho laola maemo a karabelo hamolemo le ho ntlafatsa boleng ba sehlahisoa.
1. Ntlafatso ea maemo a silicon carbide 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. Ka har'a sebaka se itseng, ha mocheso oa karabelo o phahame, lebelo la karabelo le potlaka 'me boleng ba sehlahisoa bo phahame. Leha ho le joalo, mocheso o phahameng haholo oa karabelo o tla boela o lebise 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 phello 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 keketsehong ea masoba le mapetsong 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 boleng ba sehlahisoa. Haeba karolelano ea boima ba reactant e sa lokela, e tla ama lebelo la karabelo le boleng ba sehlahisoa.
(4) Nako ea karabelo: Nako ea karabelo ke e 'ngoe ea lintlha tse 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 boela e lebise keketseho ea masoba le mapetsong sehlahisoa, e leng se amang boleng ba sehlahisoa.
2. Taolo ea ts'ebetso ea khabide ea silicon e kenyang karabelo
Mokhoeng oa karabelo ea carbide ea silicon e sintered, ho hlokahala ho laola mokhoa oa karabelo. Sepheo sa taolo ke ho netefatsa hore karabelo e tsitsitse 'me boleng ba sehlahisoa bo tsitsitse. 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 ts'ebetso e tsitsitseng 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, hoa khoneha ho netefatsa botsitso ba ts'ebetso ea karabelo le ho tsitsa ha boleng ba sehlahisoa. Tlhahisong ea sejoale-joale, sepakapaka hangata se laoloa ke sistimi ea taolo ea khomphutha.
(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 carbide ea silicon e sintered reaction-sintered ke mohato oa bohlokoa oa ho lokisa thepa ea silicon carbide ea 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. Lits'ebetsong tse 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.
