Sintered silicon carbide yakakosha ceramic zvinhu, iyo inoshandiswa zvakanyanya mukupisa kwepamusoro, kudzvanywa kwepamusoro uye minda yakasimba. Reaction sintering ye sic inhanho yakakosha mukugadzirira sintered SIC zvinhu. Iyo yakakwana kudzora kwe sintered silicon carbide reaction inogona kutibatsira kudzora zvirinani maitiro ekuita uye kugadzirisa mhando yechigadzirwa.
1. Optimization of reaction sintering silicon carbide mamiriro
Mamiriro ekuita akakosha parameters ye sintered silicon carbide reaction, inosanganisira reaction tembiricha, reaction pressure, reactant mass ratio uye nguva yekuita. Paunenge uchigadzirisa mamiriro ekuita, zvinodikanwa kugadzirisa zvinoenderana nezvinodiwa zvekushandisa uye maitiro ekuita.
(1) Reaction tembiricha: Kubata tembiricha ndechimwe chezvinhu zvakakosha zvinokanganisa kukurumidza kuita uye kunaka kwechigadzirwa. Mukati mehumwe danho, kukwirisa tembiricha yekuita, ndiko kukurumidza kwekuita uye kukwira kwemhando yechigadzirwa. Nekudaro, yakawandisa yekudziya tembiricha inotungamira zvakare mukuwedzera kwepores uye kuputika muchigadzirwa, zvichikanganisa kunaka kwechigadzirwa.
(2) Rection pressure: Reaction pressure ine chekuita nekumhanya kwekuita uye density yechigadzirwa. Mukati mehumwe danho, kukwirisa kudzvanywa kwemaitiro, ndiko kukurumidza kwekukurumidza kuita uye kukwirisa kwechigadzirwa. Nekudaro, yakawandisa yekumanikidza yekumanikidza inogona zvakare kutungamira mukuwedzera kwe pores uye kuputika muchigadzirwa.
(3) Reactant mass ratio: The reactant mass ratio ndechimwe chinhu chakakosha chinokanganisa kukurumidza kuita uye kunaka kwechigadzirwa. Kana huwandu hwehuwandu hwekabhoni kune silicon hwakakodzera, chiyero chekuita uye mhando yechigadzirwa. Kana iyo reactant mass reshiyo isina kukodzera, inokanganisa maitiro ekumhanya uye mhando yechigadzirwa.
(4) Nguva yekuita: Nguva yekuita chimwe chezvinhu zvinokanganisa kukurumidza kuita uye kunaka kwechigadzirwa. Mukati mehumwe danho, iyo nguva yakareba yekuita, inononoka kukurumidza kuita uye inokwidza kunaka kwechigadzirwa. Nekudaro, nguva yakarebesa yekuita nguva zvakare ichatungamira mukuwedzera kwepores uye kuputika muchigadzirwa, zvichikanganisa kunaka kwechigadzirwa.
2. Reaction-sintering silicon carbide process control
Mukuita maitiro e sintered silicon carbide, zvinodikanwa kudzora maitiro ekuita. Chinangwa chekudzora ndechekuona kuti maitiro akagadzikana uye mhando yechigadzirwa inowirirana. Kudzora kwekuita maitiro kunosanganisira kutonga kwekushisa, kudzora kudzvinyirira, kudzora kwemhepo uye reactant yemhando yekudzora.
(1) Kudzora tembiricha: Kudzora tembiricha ndechimwe chezvinhu zvakakosha zvemaitiro maitiro ekudzora. Kudzora tembiricha Tembiricha yekuita inofanirwa kudzorwa nemazvo sezvinobvira kuti ive nechokwadi chekugadzikana kwekuita maitiro uye kuenderana kwechigadzirwa mhando. Mukugadzirwa kwemazuva ano, komputa inodzora system inowanzoshandiswa kunyatso kudzora tembiricha yekuita.
(2) Kudzora kudzvinyirira: Kudzora kudzvinyirira chimwe chinhu chakakosha chekuita maitiro ekudzora. Nekudzora kumanikidzwa kwekuita, kugadzikana kwemaitiro ekuita uye kuenderana kwemhando yechigadzirwa kunogona kuve nechokwadi. Mukugadzirwa kwemazuva ano, komputa inodzora system inowanzo shandiswa kudzora nemazvo maitiro ekumanikidza.
(3) Atmosphere control: Atmosphere control (Atmosphere control) zvinoreva kushandiswa kwemamiriro ekunze (semhepo inert) mukuita maitiro ekudzora maitiro ekuita. Nekudzora mamiriro ekunze, zvinokwanisika kuve nechokwadi kugadzikana kwemaitiro ekuita uye kuenderana kwemhando yechigadzirwa. Mukugadzirwa kwemazuva ano, mhepo inowanzodzorwa nekombiyuta control system.
(4) Reactant quality control: Reactant quality control ndechimwe chezvinhu zvakakosha kuti ive nechokwadi chekugadzikana kwemaitiro ekuita uye kuenderana kwemhando yechigadzirwa. Nekudzora kunaka kweanogadzirisa, kugadzikana kwemaitiro ekuita uye kuenderana kwemhando yechigadzirwa kunogona kuve nechokwadi. Mukugadzirwa kwemazuva ano, komputa inodzora system inowanzoshandiswa kudzora kunaka kwe reactants.
Iyo yakakwana kudzora kwekuita-sintered silicon carbide ndiyo nhanho yakakosha yekugadzirira yakakwira mhando sintered silicon carbide zvinhu. Nekukwenenzvera mamiriro ekuita, kudzora maitiro ekuita uye kutarisa maitiro ezvigadzirwa, kugadzikana kwemaitiro ekuita uye kuenderana kwemhando yechigadzirwa kunogona kuve nechokwadi. Mumashandisirwo anoshanda, iyo sintered silicon carbide reaction inoda kugadziridzwa zvinoenderana neyakajeka application mamiriro kusangana neakasiyana maapplication zvinodiwa.
