Izingxenye ze-ceramic ze-SiC zezimboni ezenziwe ngokwezifiso ezimelana nokuguguleka kanye nokushisa okuphezulu

Ukumelana nokushisa kwezitsha zobumba ze-silicon carbide

I-silicon carbide ceramics (i-SiC ceramics) uhlobo olusha lwezinto ze-ceramic ezinobulukhuni obuphezulu, amandla aphezulu kanye nokumelana nokuguguleka okuphezulu. Ingxenye yayo eyinhloko yi-silicon carbide, futhi isakhiwo sayo sekristalu sinokuzinza okuphezulu kakhulu kokushisa kanye namakhemikhali. Ukuhlolwa kubonisa ukuthi i-silicon carbide ceramics ingagcina ukusebenza okuzinzile ngaphansi kwendawo yokushisa ephezulu kakhulu, futhi ukumelana kwayo nokushisa kungcono kakhulu kunokwezinto ze-ceramic zendabuko.

Ngokusho kocwaningo, ukumelana kwezinga lokushisa kwe-silicon carbide ceramics kungafinyelela ngaphezu kwama-degree Celsius angu-2000. Ezingeni lokushisa eliphezulu kangaka, i-silicon carbide ceramics isalondoloza izakhiwo ezinhle zemishini kanye nokuqina kwesakhiwo, okwenza ibe nohlu olubanzi lwamathemba okusetshenziswa endaweni eshisa kakhulu.

Ithuba lokusebenzisa izinto zobumba ze-silicon carbide

1. Izindiza

Embonini yezindiza, izindawo ezinokushisa okuphezulu azinakugwenywa. Ukuqina kokushisa okuphezulu kwe-silicon carbide ceramics kwenza kube ukukhetha okuhle kwezinto zokwakha ezinokushisa okuphezulu njengezinjini zezindiza kanye nama-rocket thruster.

2. Imboni yamandla namakhemikhali

Emkhakheni wamandla namakhemikhali, ama-reactor okushisa okuphezulu kanye nama-heat exchanger kanye neminye imishini inezidingo eziphezulu zokumelana nokushisa kwezinto. Ukuqina kokushisa okuphezulu kwe-silicon carbide ceramics kwenza kube yinto ekhethwayo kula madivayisi.

3. Imishini yezimboni

Emkhakheni wemishini yezimboni, ukuzinza kwezinga lokushisa eliphezulu kwe-silicon carbide ceramics kungathuthukisa ukumelana nokuguguleka kanye nokumelana nokugqwala kwemishini yemishini futhi kwandise impilo yenkonzo yemishini.

Izitsha zobumba ze-silicon carbide zinamathuba amaningi okusetshenziswa ngenxa yokuqina kwazo okuhle kakhulu ekushiseni okuphezulu. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, kukholelwa ukuthi insimu yokusetshenziswa kwezitsha zobumba ze-silicon carbide izoba nkulu kakhulu, ilethe ukulula kanye nentuthuko emphakathini wesintu.
