Izindlela Zokwakha I-Silicon Carbide Ceramics

Izindlela Zokwakha I-Silicon Carbide Ceramics: Ukubuka Konke Okuphelele

Isakhiwo sekristalu esiyingqayizivele kanye nezakhiwo ze-silicon carbide ceramics kunegalelo ezimpahleni zayo ezinhle kakhulu. Zinamandla amahle kakhulu, ubulukhuni obuphezulu kakhulu, ukumelana nokuguguleka okuhle kakhulu, ukumelana nokugqwala, ukuhanjiswa okuphezulu kokushisa kanye nokumelana okuhle nokushaqeka kokushisa. Lezi zakhiwo zenza i-silicon carbide ceramics ifaneleke kakhulu ekusetshenzisweni kwe-ballistic.

Ukwakhiwa kwe-silicon carbide ceramics kuvame ukusebenzisa izindlela ezilandelayo:

1. Ukubumba ngokucindezela: Ukubumba ngokucindezela kuyindlela esetshenziswa kabanzi ekwenzeni amashidi angangenwa yizinhlamvu e-silicon carbide. Inqubo ilula, kulula ukuyisebenzisa, isebenza kahle kakhulu futhi ifanele ukukhiqizwa okuqhubekayo.

2. Ukubumba ngomjovo: Ukubumba ngomjovo kunokuzivumelanisa nezimo okuhle kakhulu futhi kungadala izimo nezakhiwo eziyinkimbinkimbi. Le ndlela inenzuzo ikakhulukazi lapho kukhiqizwa izingxenye ze-silicon carbide ceramic ezimise okwehlukile.

3. Ukucindezela kwe-Cold isostatic: Ukucindezela kwe-Cold isostatic kuhilela ukusetshenziswa kwamandla afanayo emzimbeni oluhlaza, okuholela ekusabalaleni kobuningi obufanayo. Lobu buchwepheshe buthuthukisa kakhulu ukusebenza komkhiqizo futhi bufanelekela ukukhiqizwa kwe-silicon carbide ceramics esebenza kahle kakhulu.

4. Ukubumba ngomjovo wejeli: Ukubumba ngomjovo wejeli kuyindlela entsha yokubumba enobukhulu obufanayo. Umzimba oluhlaza okhiqizwayo unesakhiwo esifanayo namandla aphezulu. Izingxenye ze-ceramic ezitholiwe zingacutshungulwa yimishini ehlukahlukene, okunciphisa izindleko zokucubungula ngemva kokusila. Ukubumba ngomjovo wejeli kufaneleka kakhulu ekwakhiweni kwezitsha ze-silicon carbide ezinezakhiwo eziyinkimbinkimbi.

Ngokusebenzisa lezi zindlela zokwakha, abakhiqizi bangathola izitsha ze-silicon carbide zekhwalithi ephezulu ezinezakhiwo ezinhle kakhulu zemishini neze-ballistic. Amandla okwenza izitsha ze-silicon carbide zibe izinhlobo ezahlukene zezimo nezakhiwo avumela ukwenza ngokwezifiso nokwenza ngcono ukuhlangabezana nezidingo ezithile zezinhlelo zokusebenza ezahlukene.

Ngaphezu kwalokho, ukusebenza kahle kwezindleko ze-silicon carbide ceramics kwandisa ukukhanga kwayo njengento ekwazi ukumelana ne-ballistic esebenza kahle kakhulu. Lokhu kuhlanganiswa kwezakhiwo ezifiselekayo kanye nezindleko ezifanelekile kwenza i-silicon carbide ceramics ibe ngumncintiswano oqinile endaweni yezivikelo zomzimba.

Ekuphetheni, i-silicon carbide ceramics yizona zinto ezihamba phambili ze-ballistic ngenxa yezakhiwo zazo ezinhle kakhulu kanye nezindlela zokubumba eziguquguqukayo. Isakhiwo sekristalu, amandla, ubulukhuni, ukumelana nokuguguleka, ukumelana nokugqwala, ukuhanjiswa kokushisa kanye nokumelana nokushaqeka kokushisa kwe-silicon carbide ceramics kwenza kube ukukhetha okukhangayo kubakhiqizi nabacwaningi. Ngezindlela ezahlukahlukene zokwakha, abakhiqizi bangenza ngokwezifiso i-silicon carbide ceramics ukuze ihlangabezane nezicelo ezithile, iqinisekise ukusebenza kahle kanye nokuvikelwa. Ikusasa le-silicon carbide ceramics liyathembisa njengoba liqhubeka nokuthuthukisa nokusebenza kahle emkhakheni wezinto ze-ballistic.

Ngokuphathelene nokuvikelwa kwe-ballistic, ukuhlanganiswa kwamashidi e-polyethylene kanye nezinto zokufaka ze-ceramic kuye kwabonakala kusebenza kakhulu. Phakathi kwezinketho ezahlukene ze-ceramic ezitholakalayo, i-silicon carbide idonsele ukunaka okukhulu kokubili ekhaya nakwamanye amazwe. Eminyakeni yamuva nje, abacwaningi nabakhiqizi bebehlola amandla e-silicon carbide ceramics njengento evikela i-ballistic esebenza kahle kakhulu ngenxa yezakhiwo zayo ezinhle kakhulu kanye nezindleko zayo eziphansi.

I-silicon carbide iyinhlanganisela eyakhiwe ngokuqoqa ama-tetrahedrons e-Si-C, futhi inezinhlobo ezimbili zekristalu, i-α ne-β. Ezingeni lokushisa elingaphansi kuka-1600°C, i-silicon carbide ikhona ngesimo se-β-SiC, futhi lapho izinga lokushisa lidlula i-1600°C, i-silicon carbide iguquka ibe yi-α-SiC. Isibopho se-covalent se-α-silicon carbide sinamandla kakhulu, futhi singagcina isibopho esinamandla aphezulu ngisho nasemazingeni okushisa aphezulu.
