I-silicon carbide ceramics: umdlali oguquguqukayo emkhakheni wezimboni

Emndenini wesayensi yezinto zokwakha, i-silicon carbide ceramics kancane kancane ivele "njengempahla eshisayo" emikhakheni yezimboni eziningi ngenxa yezakhiwo zayo eziyingqayizivele. Namuhla, ake singene emhlabeni wei-silicon carbide ceramicsfuthi ubone lapho edlula khona.
I-Aerospace: Ukuphishekela I-Lightweight kanye nokusebenza okuphezulu
Imboni ye-aerospace inezidingo eziphakeme kakhulu zezinto zokwakha, ezingadingi nje kuphela ukuthi zibe lula ngokwanele ukunciphisa isisindo sendiza, kodwa futhi zibe namandla amahle kakhulu nokumelana nokushisa okuphezulu. Ukuminyana okuphansi nezici ezithile zamandla eziqondile ze-silicon carbide ceramics ziwenza abe into efanelekile yokukhiqiza izingxenye zenjini yendiza kanye nezingxenye zesakhiwo sendiza. Cabanga ukuthi endaweni yokushisa ephezulu kanye nengcindezi ephezulu yenjini yendiza, ama-turbine blades kanye nezingxenye zegumbi elivuthayo ezenziwe nge-silicon carbide ceramics azikwazi nje ukumelana namazinga okushisa aphezulu, kodwa futhi zisize injini ithuthukise ukusebenza kahle futhi inciphise ukusetshenziswa kwamandla ngesisindo esilula. Akumangalisi yini? Ngaphezu kwalokho, ukuzinza kwayo okuhle kakhulu kwe-thermal kungaqinisekisa ukuthi izingxenye ngeke zikhubazeke noma zonakaliswe ngenxa yokushintsha kwezinga lokushisa lapho indiza ikhiqiza ukushisa okukhulu phakathi nokundiza kwesivinini esikhulu, okuhlinzeka ngokuvikeleka kokuphepha kwendiza.

Ukukhiqiza I-Semiconductor: Usekelo Oluyinhloko Lwezinqubo Zokunemba
Ukukhiqizwa kwe-semiconductor yinkambu edinga ukunemba okuqinile nokusebenza kwempahla. I-silicon carbide ceramics idlala indima ebaluleke kakhulu kumadivayisi we-semiconductor ngenxa yokuqina kwawo okuphezulu, i-coefficient ephansi yokwanda okushisayo, nokuzinza okuhle kakhulu kwamakhemikhali. Ezinqubweni ezibalulekile ezifana ne-photolithography kanye ne-etching, abathwali be-wafer kanye nokulungiswa okunembayo okwenziwe nge-silicon carbide ceramics kungaqinisekisa ukuma okunembe okuphezulu kwamawafa e-silicon ngesikhathi sokucubungula, okuqinisekisa ukunemba kokukhiqizwa kwama-chip. Ngesikhathi esifanayo, ukumelana nokugqwala kwayo kuma-reagents ahlukahlukene amakhemikhali kanye ne-plasma kwandisa kakhulu impilo yesevisi yemishini, kunciphisa izindleko zokukhiqiza, futhi kukhuthaze ukuthuthukiswa okuqhubekayo kobuchwepheshe be-semiconductor kumasayizi amancane nokusebenza okuphezulu.
Umkhakha wezamandla: Ukubhekana nezinselele zokushisa okuphezulu nokugqwala
Embonini yamandla, kungakhathaliseki ukuthi amandla endabuko ashisayo, imboni yamakhemikhali, noma amandla enuzi avelayo kanye nelanga, zonke zibhekana nezimo zokusebenza eziyinkimbinkimbi ezifana nezinga lokushisa eliphezulu kanye nokugqwala. Kuma-boilers okukhiqiza amandla ashisayo, ama-nozzles okushisa kanye nezingxenye zokushintshanisa ukushisa ezenziwe nge-silicon carbide ceramics zingamelana nokuguguleka kwamalangabi okushisa okuphezulu namagesi abolayo, ukuthuthukisa ukusebenza kahle nokusebenza nokuthembeka kwemishini; Emkhakheni wamandla enuzi, izitsha ze-silicon carbide ceramics zisetshenziswa ekufakeni uphethiloli, izinto zokwakha, njll. zama-reactors enuzi ngenxa yokumelana kwazo nezinga lokushisa eliphakeme kakhulu nokumelana nemisebe, kuqinisekisa ukuqhubeka okuphephile nokuzinzile kokusabela kwe-nuclear; Embonini ye-solar photovoltaic, i-silicon carbide ceramics ingasetshenziswa ukwenza amadivaysi athwala imithwalo ezithandweni zokushisa okuphezulu, isekela ngokuqinile ukucutshungulwa kwezinto ezifana nama-silicon wafers ezindaweni ezinokushisa okuphezulu, nokusiza ukuthuthukisa ukusebenza kahle kokuguqulwa kwamandla elanga.
Ukucutshungulwa komshini: isiqinisekiso sokumelana nokugqoka kanye nokunemba okuphezulu
Emkhakheni wokucutshungulwa kwemishini, ubulukhuni obuphezulu nokumelana nokugqoka kwe-silicon carbide ceramics kuyenza ibe yikhwalithi ephezulu yokukhiqiza amathuluzi okusika, amathuluzi okugaya, ama-bearings nezinye izakhi. Uma sisebenzisa amathuluzi okusika i-silicon carbide ceramic ukusika izinto zensimbi, angakwazi ukubhekana kalula namandla okusika amandla aphezulu, agcine ubukhali be-blade, athuthukise kakhulu ukucubungula ukusebenza kahle nokunemba, ukunciphisa ukugqoka kwamathuluzi kanye nemvamisa yokubuyisela. Ama-silicon carbide ceramic bearings, ane-coefficient yawo ephansi ye-friction kanye nokuqina okuhle, angasebenza ngokuzinzile, anciphise ukusetshenziswa kwamandla, futhi andise impilo yesevisi yemishini yemishini ejikelezayo enesivinini esikhulu, enikeza ukwesekwa okuqinile kokuthuthukiswa okuphumelelayo kwemboni yokukhiqiza imishini.
I-silicon carbide ceramics, ngokusebenza kwayo okuhle kakhulu, ithole isiteji sayo emikhakheni eminingi yezimboni, futhi ngenqubekelaphambili eqhubekayo yobuchwepheshe, amathemba okusebenza kwayo azoba banzi, afake ubungqabavu obusha ekuthuthukisweni kwezimboni ezahlukahlukene.
