Sintered silicon carbide ke thepa ea bohlokoa ea ceramic, e sebelisoang haholo mocheso o phahameng, khatello e phahameng le masimo a matla a phahameng. Reaction sintering of sic ke mohato oa bohlokoa oa ho lokisa lisebelisoa tsa SIC tse sirelelitsoeng. Taolo e nepahetseng ea sintered silicon carbide reaction e ka re thusa ho laola maemo a karabelo hantle le ho ntlafatsa boleng ba sehlahisoa.
1. Optimization ea karabelo sintering silicon carbide maemo
Maemo a karabelo ke likarolo tsa bohlokoa tsa karabelo ea sintered silicon carbide, ho kenyeletsoa mocheso oa karabelo, khatello ea karabelo, karohano ea boima ba reactant le nako ea karabelo. Ha o ntlafatsa maemo a karabelo, hoa hlokahala ho ikamahanya le litlhoko tse ikhethileng tsa kopo le mochini oa karabelo.
(1) Thempereichara ea karabelo: Mocheso oa karabelo ke e 'ngoe ea lintlha tsa bohlokoa tse amang lebelo la karabelo le boleng ba sehlahisoa. Ka har'a mefuta e itseng, ha mocheso oa karabelo o phahame, lebelo la karabelo le potlaka le boleng bo phahameng ba sehlahisoa. Leha ho le joalo, mocheso o phahameng haholo oa karabelo o tla boela o lebise ho eketseha ha li-pores le mapetsong a sehlahisoa, ho ama boleng ba sehlahisoa.
(2) Khatello ea karabelo: Khatello ea karabelo e boetse e na le phello ho lebelo la karabelo le boima ba sehlahisoa. Ka har'a mefuta e itseng, ha khatello ea karabelo e phahame, lebelo la karabelo le potlaka le ho phahama ha sehlahiswa. Leha ho le joalo, khatello e phahameng haholo ea karabelo e ka boela ea lebisa ho eketseha ha li-pores le mapetsong a sehlahisoa.
(3) Reactant boima karo-karolelano: The reactant boima karo-karolelano ke ntlha e 'ngoe ea bohlokoa e amang lebelo karabelo le boleng ba sehlahisoa. Ha karo-karolelano ea boima ba carbon ho silicon e loketse, sekhahla sa karabelo le boleng ba sehlahisoa. Haeba reactant boima karo-karolelano e se e loketseng, e tla ama karabelo lebelo le boleng ba sehlahisoa.
(4) Nako ea ho itšoara: Nako ea ho itšoara ke e 'ngoe ea lintlha tse amang lebelo la ho arabela le boleng ba sehlahisoa. Ka har'a mefuta e itseng, ha nako ea karabelo e lelelele, lebelo la karabelo le ea butle 'me boleng ba sehlahisoa bo phahame. Leha ho le joalo, nako e telele haholo ea karabelo e tla boela e lebise ho eketseha ha li-pores le mapetsong a sehlahisoa, ho ama boleng ba sehlahisoa.
2. Reaction-sintering silicon carbide process control
Ts'ebetsong ea karabelo ea sintered silicon carbide, hoa hlokahala ho laola ts'ebetso ea karabelo. Sepheo sa taolo ke ho netefatsa hore karabelo e tsitsitse le boleng ba sehlahisoa bo tsitsitse. Taolo ea ts'ebetso 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 tšebetso 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 komporo hangata e sebelisoa ho laola ka nepo mocheso oa karabelo.
(2) Taolo ea khatello: Ho laola khatello ke karolo e 'ngoe ea bohlokoa ea ho laola mokhoa oa ho itšoara. Ka ho laola khatello ea maikutlo, botsitso ba mokhoa oa ho itšoara le ho lumellana ha boleng ba sehlahisoa ho ka netefatsoa. Tlhahisong ea sejoale-joale, sistimi ea taolo ea komporo hangata e sebelisoa ho laola ka nepo khatello ea maikutlo.
(3) Taolo ea atmosphere: Taolo ea atmosphere e bolela tšebeliso ea sepakapaka se itseng (joalo ka sepakapaka se sa sebetseng) ts'ebetsong ea ho laola mokhoa oa ho itšoara. Ka ho laola sepakapaka, hoa khoneha ho netefatsa botsitso ba mokhoa oa ho arabela le ho lumellana ha boleng ba sehlahisoa. Tlhahisong ea morao-rao, sepakapaka se atisa ho laoloa ke tsamaiso ea lik'homphieutha.
(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 ho ts'oana ha boleng ba sehlahisoa. Ka ho laola boleng ba li-reactants, botsitso ba mokhoa oa ho arabela le ho tsitsa ha boleng ba sehlahisoa ho ka netefatsoa. Tlhahisong ea sejoale-joale, sistimi ea taolo ea likhomphutha hangata e sebelisoa ho laola boleng ba li-reactants.
Taolo e nepahetseng ea karabelo-sintered silicon carbide ke mohato oa bohlokoa oa ho lokisa lisebelisoa tsa boleng bo holimo tsa sintered silicon carbide. 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 ho ka netefatsoa. Lits'ebetsong tse sebetsang, karabelo ea sintered silicon carbide e hloka ho lokisoa ho latela maemo a ikhethileng a kopo ho fihlela litlhoko tse fapaneng tsa kopo.
