Sintered silicon carbide chinhu chakakosha checeramic zvinhu, chinoshandiswa zvakanyanya mukupisa kwakanyanya, kudzvanywa kwakanyanya uye minda yakasimba. Reactive sintering yeSIC inhanho yakakosha mukugadzirira sintered SIC zvinhu. Iko kwakaringana kudzora kwekuita sintering SIC reaction kunogona kutibatsira kudzora maitiro ekuita uye kugadzirisa mhando yechigadzirwa. Iyo yakakwana yekudzora nzira ye sintered silicon carbide reaction inokurukurwa mupepa rino.
1. Optimization of reaction sintering SIC 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: Rection tembiricha ndechimwe chezvinhu zvakakosha zvinokanganisa kukurumidza kuita uye kunaka kwechigadzirwa. Mune imwe nzvimbo, iyo yakanyanya kupisa tembiricha, iyo inokurumidza kukurumidza kuita, inokwidza kunaka kwechigadzirwa. Nekudaro, yakanyanya kupisa tembiricha inotungamira kukuwedzera kwe pores 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 kuita kumanikidza kunogona zvakare kutungamira kune akawanda pores uye kuputika muchigadzirwa.
(3) reactant mass ratio: reactant mass ratio chimwe chinhu chakakosha chinokanganisa kukurumidza kwekuita uye mhando yechigadzirwa. Kana iyo kabhoni kune silicon misa chiyero yakakodzera, reaction rate uye chigadzirwa misa. Kana iyo reactant mass reshiyo isina kukodzera, inozokanganisa chiyero chekuita uye huwandu hwechigadzirwa.
(4) Nguva yekuita: Nguva yekuita chimwe chezvinhu zvinokanganisa kukurumidza kwekuita uye kunaka kwechigadzirwa. Mukati mehumwe danho, iyo nguva yakareba yekuita, inononoka kukurumidza kuita uye inokwidza kunaka kwechigadzirwa. Zvisinei, nguva yakareba yekupindura ichaita kuti kuwedzerwa kwe pores uye kuputika kwechigadzirwa, kunokanganisa kunaka kwechigadzirwa.
2. Process control ye reactive sintering silicon carbide
Mukuita sintering SIC reaction, zvinodikanwa kudzora maitiro ekuita. Chinangwa chekudzora ndechekuona kugadzikana kwemaitiro uye kuenderana kwemhando yechigadzirwa. Reaction process control inosanganisira kudzora tembiricha, kudzora kumanikidza, kudzora mamiriro ekunze uye reactant yemhando yekudzora.
(1) Kudzora tembiricha: Kudzora tembiricha ndechimwe chezvinhu zvakakosha zvemaitiro maitiro ekudzora. Kudzora tembiricha Tembiricha yekuita inofanirwa kudzorwa chaizvo sezvinobvira kuti ive nechokwadi chekugadzikana kwemaitiro ekuita uye kuenderana kwemhando yechigadzirwa. 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 kwemhepo chaiyo (yakadai semhepo inert) mukuita maitiro kudzora maitiro ekuita. Nekudzora mamiriro ekunze, kugadzikana kwemaitiro ekuita uye kuenderana kwemhando yechigadzirwa kunogona kuve nechokwadi. Mukugadzirwa kwemazuva ano, komputa inodzora system inowanzoshandiswa kudzora mhepo.
(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.
Yakanyanya kudzora ye reactive sintering SIC inhanho yakakosha yekugadzirira yakakwira mhando sintered SIC zvinhu. Nekugadzirisa maitiro ekuita, kudzora maitiro ekuita uye yekutarisa maitiro ezvigadzirwa, kugadzikana kwemaitiro maitiro uye kuenderana kwemhando yechigadzirwa kunogona kuvimbiswa. Mukushanda kwekushandisa, maitiro e-sintered silicon carbide anoda kugadziridzwa zvinoenderana neakananga maficha ekushandisa kuti asangane nezvinodiwa zvakasiyana zvekushandisa.
