Izingxenye zefekthri ze-ceramic zangokwezifiso ze-SiC zezimboni zimelana nokugqokwa kanye nezinga lokushisa eliphezulu

Ukumelana nezinga lokushisa kwe-silicon carbide ceramics

I-silicon carbide ceramics (i-SiC ceramics) iwuhlobo olusha lwe-ceramic material enobulukhuni obuphezulu, amandla aphezulu kanye nokumelana nokugqoka okuphezulu. Ingxenye yayo eyinhloko i-silicon carbide, futhi isakhiwo sayo sekristalu sinokuzinza okuphezulu kakhulu okushisayo namakhemikhali. Ukuhlola kubonisa ukuthi i-silicon carbide ceramics ingagcina ukusebenza okuzinzile ngaphansi kwemvelo yokushisa ephezulu kakhulu, futhi ukumelana kwayo kwezinga lokushisa kungcono kakhulu kunokwezinto ze-ceramic zendabuko.

Ngokusho kocwaningo, ukumelana nezinga lokushisa kwe-silicon carbide ceramics kungafinyelela ngaphezu kwama-degrees Celsius angama-2000. Emazingeni okushisa aphezulu kangaka, i-silicon carbide ceramics isagcina izakhiwo ezinhle zemishini kanye nokuzinza kwesakhiwo, okwenza kube nohlu olubanzi lwamathemba okufaka isicelo endaweni yokushisa ephezulu.

Ithemba lesicelo se-silicon carbide ceramics

1. Umkhathi

Embonini ye-aerospace, izindawo ezinezinga lokushisa eliphezulu azinakugwenywa. Ukuzinza okuphezulu kwezinga lokushisa kwe-silicon carbide ceramics kukwenza kube ukukhetha okuhle kwempahla ezingxenyeni zokushisa okuphezulu njengezinjini zezindiza namarokhethi amarokhethi.

2. Imboni yamandla namakhemikhali

Emkhakheni wezimboni zamandla namakhemikhali, ama-reactors okushisa aphezulu kanye nezishintshi zokushisa nezinye izinto zokusebenza zinezidingo eziphakeme zokumelana nezinga lokushisa kwezinto. Ukuzinza okuphezulu kwezinga lokushisa kwe-silicon carbide ceramics kwenza kube yinto yokuzikhethela kulawa madivayisi

3. Imishini yezimboni

Emkhakheni wemishini yezimboni, ukuzinza okuphezulu kwezinga lokushisa kwe-silicon carbide ceramics kungathuthukisa ukumelana nokuguga kanye nokumelana nokugqwala kwemishini eyimishini futhi kwandise impilo yesevisi yemishini.

I-silicon carbide ceramics inamathemba okusebenza abanzi ngenxa yokuqina kwayo okuhle kakhulu kwezinga lokushisa. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, kukholakala ukuthi inkambu yesicelo se-silicon carbide ceramics izoba nkulu kakhulu, ilethe ukunethezeka nenqubekela phambili emphakathini wesintu.
