Pagal form\u0105 silicio karbido pluo\u0161to rink\u0105 galima suskirstyti \u012f i\u0161tisinius ir austus silicio karbido pluo\u0161to gaminius. Did\u0117jant pramoninei gamybai aviacijos ir gynybos sektoriuose ir energetikos pramon\u0117je, kurioje i\u0161tisinis silicio karbido pluo\u0161tas naudojamas branduoliniams reaktoriams kurti, tai yra pagrindiniai veiksniai.<\/p>\n
Silicio karbido pluo\u0161tas yra atsparus auk\u0161tai temperat\u016brai, tod\u0117l jis puikiai tinka metalams ir plastikams sutvirtinti, gaminant kompozitus, pasi\u017eymin\u010dius dideliu tempimo stipriu ir tamprumo moduliu. Be to, silicio karbido pluo\u0161to elektrodai pla\u010diai naudojami krosnyse ir indukcin\u0117se virykl\u0117se kaip pramoninis kaitinimo \u0161altinis; be to, jis gali b\u016bti legiruojamas azoto, fosforo, aliuminio ar galio legiruojan\u010diomis med\u017eiagomis, kad b\u016bt\u0173 gaminami n ir p tipo puslaidininkiai.<\/p>\n
Silicio karbidas gerai atlaiko auk\u0161t\u0105 temperat\u016br\u0105, yra chemi\u0161kai stabilus ir matmen\u0173 po\u017ei\u016briu pastovus, tod\u0117l jis yra puiki med\u017eiaga puslaidininki\u0173 krosni\u0173 plok\u0161teli\u0173 pad\u0117kl\u0173 atramoms ir pad\u0117kliukams, taip pat naudojamas krosni\u0173 \u012fd\u0117klams, dilimo plok\u0161t\u0117ms ir \u012fd\u0117kl\u0173 vamzd\u017eiams elektronikos gamybos \u012fmon\u0117se.<\/p>\n
Tiek i\u0161sivys\u010diusiose, tiek besivystan\u010diose \u0161alyse spar\u010diai statomi branduoliniai objektai, tod\u0117l gali padid\u0117ti energijos ir galios komponent\u0173, kuri\u0173 sud\u0117tyje yra silicio karbido pluo\u0161to izoliacini\u0173 med\u017eiag\u0173, pavyzd\u017eiui, elektros reaktori\u0173, kuriuose jos pla\u010diai naudojamos kaip izoliacin\u0117 med\u017eiaga, paklausa.<\/p>\n
Auk\u0161tai temperat\u016brai atspari\u0173 silicio karbido pluo\u0161t\u0173 gamybos metodai susideda i\u0161 trij\u0173 etap\u0173: pirmtak\u0173 pluo\u0161t\u0173 gavimas polikarbosilano lydymo b\u016bdu, \u0161i\u0173 pirmtak\u0173 pluo\u0161t\u0173 panardinimas \u012f reakcijos monomerus mirkymui ir kietinimui, kad b\u016bt\u0173 pasiektas idealus 0,1-0,99 skersmens skersmens ir sluoksnio storio santykis, ir galiausiai krekingas inertin\u0117se dujose, kad b\u016bt\u0173 gauti SiC pluo\u0161tai, pasi\u017eymintys puikiu atsparumu temperat\u016brai, taip pat ma\u017eesn\u0117mis gamybos s\u0105naudomis ir tinkamomis lenkiamosiomis savyb\u0117mis. Galutiniai produktai pasi\u017eymi puikiu atsparumu auk\u0161tai temperat\u016brai, ma\u017eomis gamybos s\u0105naudomis ir geromis lenkiamosiomis savyb\u0117mis, tinkamomis j\u0173 taikymui.<\/p>\n
Silicio karbido pluo\u0161tas naudojamas kaip keramini\u0173 matricini\u0173 kompozit\u0173 (CMC) armavimo med\u017eiaga. D\u0117l savo savybi\u0173 jis tinka naudoti daugelyje energetikos pramon\u0117s sri\u010di\u0173, pavyzd\u017eiui, angli\u0173 elektrin\u0117se ir branduoliniuose reaktoriuose, taip pat kar\u0161\u010diui atspariose u\u017euolaidose ir dir\u017euose. Silicio karbido pluo\u0161to atsparumas auk\u0161toms temperat\u016broms ir ilgaam\u017ei\u0161kumas lemia, kad jis yra puikus pasirinkimas kaip sudedamoji CMC armuojam\u0173j\u0173 med\u017eiag\u0173, pavyzd\u017eiui, kar\u0161\u010diui atspari\u0173 u\u017euolaid\u0173 ar dir\u017e\u0173, dalis.<\/p>\n
Nuo 2008 m. padaryta didel\u0117 pa\u017eanga silicio karbido pluo\u0161to gamybos technologijose, tod\u0117l buvo sukurti beveik stechiometriniai ma\u017eo skersmens pluo\u0161tai, kuri\u0173 savyb\u0117s tinka daugumai keramini\u0173 matric\u0173 kompozit\u0173 (CMC) ir branduolini\u0173 \u012frengini\u0173. Deja, gamybos s\u0105naudos vis dar riboja j\u0173 naudojim\u0105.<\/p>\n
Silicio karbido pluo\u0161to paklausa \u0160iaur\u0117s Amerikoje spar\u010diai auga, nes ple\u010diasi aviacijos ir karin\u0117 pramon\u0117 d\u0117l didel\u0117s komercini\u0173 orlaivi\u0173 paklausos ir did\u0117jan\u010di\u0173 i\u0161laid\u0173 gynybai regione. Did\u0117jan\u010dios i\u0161laidos tur\u0117t\u0173 skatinti hibridini\u0173 aliuminio metalo matricos kompozit\u0173, sutvirtint\u0173 silicio karbido pluo\u0161tu, gamyb\u0105.<\/p>\n
Pasaulin\u0117 silicio karbido pluo\u0161to rinka gali b\u016bti suskirstyta pagal form\u0105 ir paskirt\u012f. 2023 m. did\u017eiausi\u0105 rinkos dal\u012f u\u017e\u0117m\u0117 i\u0161tisiniai silicio karbido pluo\u0161tai, ir prognozuojama, kad 2024-2030 m. j\u0173 sud\u0117tinis metinis augimas sieks 35,9%. \u0160iuos lengvai apdirbamus pluo\u0161tus galima lengvai integruoti \u012f sud\u0117tingos formos komponentus, o j\u0173 atsparumas spinduliuotei traukia branduolin\u0117s energijos gamybos pramon\u0117s atstov\u0173 d\u0117mes\u012f.<\/p>\n
Silicio karbido pluo\u0161tas gali pad\u0117ti orlaivi\u0173 varikliams suma\u017einti svor\u012f ir s\u0105naudas, nes suma\u017e\u0117ja svorio laikan\u010di\u0173j\u0173 med\u017eiag\u0173. Ta\u010diau j\u012f gaminant susiduriama su tam tikrais i\u0161\u0161\u016bkiais, pavyzd\u017eiui, reikia, kad jis atlaikyt\u0173 auk\u0161t\u0105 temperat\u016br\u0105 ir nesutr\u016bkin\u0117t\u0173, taip pat reikia, kad med\u017eiagos b\u016bt\u0173 atsparios korozijai ir nuovargiui.<\/p>\n
Viena i\u0161 kompozit\u0173 tobulinimo galimybi\u0173 - sukurti naujus metalus, kurie geriau atitikt\u0173 armuojam\u0105sias med\u017eiagas ir armuojamuosius metalus, tod\u0117l kompozitai b\u016bt\u0173 tvirtesni ir patvaresni. Kitas b\u016bdas gal\u0117t\u0173 b\u016bti keramini\u0173 matric\u0173 naudojimas, d\u0117l kuri\u0173 kompozitai tapt\u0173 lengvesni, bet kartu b\u016bt\u0173 galima formuoti \u012fvairi\u0173 form\u0173 pluo\u0161tus.<\/p>\n
Reaktyvini\u0173 varikli\u0173 komponentams gaminami boro pluo\u0161tu sustiprinti aliuminio matricos kompozitai yra du kartus tvirtesni ir atsparesni kar\u0161\u010diui nei nikelio lydiniai, ta\u010diau j\u0173 gamyba kainuoja apie $100 ma\u017eiau u\u017e svar\u0105 - tai yra gerokai daugiau nei \u012fprasti nikelio lydiniai, kurie \u0161iuo metu yra standartiniai daugeliui orlaivi\u0173 komponent\u0173.<\/p>\n
Norint sukurti metal\u0173 matricos kompozitus, sustiprintus boru, silicio karbido pluo\u0161tai pirmiausia turi b\u016bti padengti metalu, kad padid\u0117t\u0173 j\u0173 dr\u0117kinamumas su matricos metalu, ir sukrauti \u012f kr\u016bvas bei kaitinami sl\u0117giu, o po to u\u017epildomi tarp kiekvienos kr\u016bvos naudojant matricos metalo miltelius, sumai\u0161ytus su organine ri\u0161am\u0105ja med\u017eiaga.<\/p>\n
Silicio karbido pluo\u0161tas yra ugniai atspari med\u017eiaga, naudojama \u012fvairiose srityse, \u012fskaitant kar\u0161\u010diui atsparias med\u017eiagas reaktyviniams varikliams ir keramini\u0173 matric\u0173 kompozitams, auk\u0161tatemperat\u016bri\u0173 dir\u017e\u0173 ir filtravimo audini\u0173 armat\u016br\u0105, auk\u0161tatemperat\u016bri\u0173 duj\u0173 ar metal\u0173 filtravim\u0105 per filtravimo audini\u0173 filtrus ir pagrindin\u0119 silicio karbidu armuot\u0173 metalo matric\u0173 kompozit\u0173 sudedam\u0105j\u0105 dal\u012f - \u0161ios sritys tur\u0117t\u0173 labai prisid\u0117ti prie rinkos pajam\u0173 augimo.<\/p>\n
Iki 2024 m. austinis silicio karbido pluo\u0161tas grei\u010diausiai dominuos pasaulin\u0117je rinkoje d\u0117l savo puiki\u0173 mechanini\u0173 savybi\u0173 ir gamybos lankstumo. Austas silicio karbido pluo\u0161tas gali b\u016bti lengvai aud\u017eiamas \u012f \u012fvairias strukt\u016bras, pavyzd\u017eiui, \u017earnas, vamzd\u017eius ar mai\u0161us, ir pasi\u017eymi puikiu atsparumu dilimui, tod\u0117l yra geriausias automobili\u0173 dali\u0173 pasirinkimas.<\/p>\n
Silicio karbido pluo\u0161tas gali pranokti tradicinius nikelio pagrindo superlydinius, nes yra du kartus stipresnis ir 20% lengvesnis, pasi\u017eymi geresniu cheminiu stabilumu, cheminiu patvarumu, atsparumu kar\u0161\u010diui, \u0161ilumos laidumu ir ilgaam\u017ei\u0161kumu. Be to, SiC kristalin\u0117 strukt\u016bra gali atlaikyti didesnio lygio tempimo \u012ftempius be deformacij\u0173 ar l\u016b\u017ei\u0173.<\/p>\n
