\u0160ios r\u016b\u0161ies silicio karbido keramikoje tiesiogiai naudojamas tam tikro dyd\u017eio daleli\u0173 pasiskirstymo silicio karbidas, kuris susimai\u0161\u0119s su anglimi sudaro embrionus, o tada auk\u0161toje temperat\u016broje angl\u0117ja. Dalis silicio reaguoja su anglimi ir susidaro SiC, kuris susijungia su pradiniame embrione esan\u010diu SIC, kad b\u016bt\u0173 pasiektas sukepinimo tikslas. Yra du anglinimo b\u016bdai: vienas j\u0173 - pasiekti silicio lydymosi temperat\u016br\u0105, generuoti silicio lydymosi temperat\u016br\u0105 ir generuoti silicio garus, Sukepinimo tikslas pasiekiamas infiltruojant silicio garus \u012f embrion\u0105. \u0160iuo b\u016bdu paruo\u0161to sukepinto SiC korpuso gamybos s\u0105naudos yra nedidel\u0117s. Ta\u010diau \u0161is procesas lemia sukepintame embrione likus\u012f laisv\u0105 silic\u012f. \u0160i silicio dalis tur\u0117t\u0173 tur\u0117ti \u012ftakos b\u016bsim\u0173 gamini\u0173 taikymui. Viena vertus, ji suma\u017eina sukepinto k\u016bno stiprum\u0105 ir atsparum\u0105 dilimui, kita vertus, d\u0117l esamo laisvojo silicio silicio karbidas tampa atsparus r\u016bg\u0161tims.<\/p>\n

Silicio karbido keramikos sukepinimas be sl\u0117gio: silicio karbido sukepinim\u0105 be sl\u0117gio galima suskirstyti \u012f kietosios faz\u0117s sukepinim\u0105 ir skystosios faz\u0117s sukepinim\u0105. Be sl\u0117gio sukepinto silicio karbido grynumas yra didelis, silicio karbido kiekis yra didesnis nei 97%, atsparumas r\u016bg\u0161\u010di\u0173 ir \u0161arm\u0173 korozijai yra daug geresnis nei reakcinio sukepinimo silicio karbido, be to, j\u012f lengva gaminti serijomis.<\/p>\n

Kar\u0161to presavimo sukepinimo silicio karbido keramika yra vienas veiksmingiausi\u0173 b\u016bd\u0173 didelio tankio silicio karbido keramikai paruo\u0161ti. Kar\u0161tai presuoto silicio karbido savyb\u0117s paprastai yra geresn\u0117s nei reakcinio sukepinimo ir be sl\u0117gio sukepinto silicio karbido savyb\u0117s, ypa\u010d smulki\u0173 gr\u016bdeli\u0173, didelio kompakti\u0161kumo ir didelio gamini\u0173 stiprumo bei kietumo.<\/p>\n

Auk\u0161tos temperat\u016bros kar\u0161to izostatinio presavimo sukepinimo silicio karbido keramika: Auk\u0161tos temperat\u016bros kar\u0161tas izostatinis presavimas yra pa\u017eangus keramikos sukepinimo procesas. Keramikos milteliai arba keramikos embrionas supakuojami ir dedami \u012f auk\u0161tos temperat\u016bros kar\u0161to izostatinio presavimo \u012frengin\u012f, o po to sukepinami \u012f tank\u0173 k\u016bn\u0105 veikiant auk\u0161tai temperat\u016brai ir dideliam sl\u0117giui. \u0160iam procesui b\u016bdingas vienalaikis ir tolygus sl\u0117gis, vadinamas HIP.<\/p>\n

Rekristalizuota silicio karbido keramika: sumai\u0161ius, suformavus ir i\u0161d\u017eiovinus \u017ealiavas, jos deginamos oro izoliacijoje esan\u010dioje auk\u0161tos temperat\u016bros elektrin\u0117je krosnyje 2300 ~ 2500 \u2103 temperat\u016broje. Kai temperat\u016bra vir\u0161ija 2100 \u2103, silicio karbidas i\u0161garuoja ir kondensuojasi, tod\u0117l susidaro rekristalizuota silicio karbido keramika be sukepimo susitraukimo ir savaiminio suri\u0161imo strukt\u016bros.<\/p>\n
