Kuyini ukugqoka kwe-silicon carbide?

Ukugqoka kwe-silicon carbide,Okuvame ukubizwa ngokuthi i-SiC coating, kubhekisela enkambisweni yokufaka ungqimba lwe-silicon carbide ezindaweni ngokusebenzisa izindlela ezifana ne-Chemical Vapor Deposition (CVD), i-Physical Vapor Deposition (PVD), noma i-thermal spray. Lokhu kuhlanganiswa kwe-silicon carbide ceramic kuthuthukisa izakhiwo zobuso zezingxenye ezahlukene ngokunikeza ukumelana nokuguguleka okumangalisayo, ukuzinza kokushisa, kanye nokuvikelwa kokugqwala. I-SiC yaziwa ngezakhiwo zayo ezivelele zomzimba nezamakhemikhali, kufaka phakathi iphuzu lokuncibilika eliphezulu (cishe ama-2700℃), ubulukhuni obukhulu (isikali se-Mohs 9), ukumelana okuhle kakhulu kokugqwala kanye ne-oxidation, kanye nokusebenza okuhle kakhulu kwe-ablation.

Izinzuzo Eziyinhloko Zokumboza I-Silicon Carbide Ezicelweni Zezimboni

Ngenxa yalezi zici, i-silicon carbide coating isetshenziswa kabanzi emikhakheni efana nezindiza, imishini yezikhali, kanye nokucubungula ama-semiconductor. Ezindaweni ezimbi kakhulu, ikakhulukazi ngaphakathi kobubanzi be-1800-2000℃, i-SiC coating ibonisa ukuzinza okuphawulekayo kokushisa kanye nokumelana nokushisa, okwenza kube kuhle kakhulu ekusetshenzisweni kwezinga lokushisa eliphezulu. Kodwa-ke, i-silicon carbide yodwa ayinalo ubuqotho besakhiwo obudingekayo ezinhlotsheni eziningi, ngakho-ke izindlela zokubopha ziyasetshenziswa ukuze kusetshenziswe izakhiwo zayo ezihlukile ngaphandle kokubeka engcupheni amandla ezingxenye. Ekukhiqizweni kwe-semiconductor, izinto ezimbozwe yi-silicon carbide zinikeza isivikelo esithembekile kanye nokuqina kokusebenza ngaphakathi kwemishini esetshenziswa ezinqubweni ze-MOCVD.

Izindlela Ezivamile Zokulungiselela Ukugqoka I-Silicon Carbide

Ⅰ● Ukufakwa Komhwamuko Wekhemikhali (i-CVD) I-Silicon Carbide Coating

Kule ndlela, izembozo ze-SiC zakhiwa ngokubeka izisekelo ekamelweni lokusabela, lapho i-methyltrichlorosilane (MTS) isebenza njengesandulela. Ngaphansi kwezimo ezilawulwayo—ngokuvamile i-950-1300°C kanye nengcindezi engemihle—i-MTS iyabola, bese i-silicon carbide ifakwa phezu komhlaba. Le nqubo yezembozo ze-CVD SiC iqinisekisa isembozo esiminyene, esifanayo esinokunamathela okuhle kakhulu, esifanele ukusetshenziswa okunembile kakhulu emikhakheni ye-semiconductor kanye ne-aerospace.

Ⅱ● Indlela Yokuguqula I-Precursor (Ukufakelwa kwe-Polymer kanye ne-Pyrolysis – PIP)

Enye indlela ephumelelayo yokumboza nge-silicon carbide spray yindlela yokuguqula i-precursor, ehilela ukucwilisa isampula elashwe ngaphambilini kwisisombululo se-ceramic precursor. Ngemva kokuhlanza ithangi lokufutha nokucindezela i-coating, isampula iyashiswa, okuholela ekwakhekeni kwe-silicon carbide coating lapho iphola. Le ndlela ithandwa kakhulu yizingxenye ezidinga ukujiya okufanayo kwe-coating kanye nokumelana nokuguguleka okuthuthukisiwe.

Izakhiwo Ezibonakalayo Ze-Silicon Carbide Coating

Izembozo ze-silicon carbide zibonisa izakhiwo ezenza zibe zilungele ukusetshenziswa kwezimboni ezidinga kakhulu. Lezi zakhiwo zifaka:

Ukushisa Okuphezulu: 120-270 W/m·K
Isilinganiso Sokwanda Kokushisa: 4.3 × 10^^(-6)/K (ku-20~800℃)
Ukumelana Nogesi: 10^⁵– 10^⁶Ω·cm
Ukuqina: Isikali se-Mohs 9

Ukusetshenziswa kwe-Silicon Carbide Coating

Ekukhiqizweni kwe-semiconductor, i-silicon carbide coating ye-MOCVD nezinye izinqubo zokushisa okuphezulu ivikela imishini ebalulekile, njenge-reactors kanye ne-susceptors, ngokunikeza kokubili ukumelana nokuqina kokushisa okuphezulu. Ezindiza kanye nokuzivikela, i-silicon carbide ceramic coatings isetshenziswa ezingxenyeni okumele zimelane nemiphumela yesivinini esikhulu kanye nezindawo ezigqwalisayo. Ngaphezu kwalokho, upende noma i-silicon carbide coating ingasetshenziswa nakumadivayisi ezokwelapha adinga ukuqina ngaphansi kwezinqubo zokubulala inzalo.

Kungani Kufanele Ukhethe I-Silicon Carbide Coating?

Njengoba inerekhodi eliqinisekisiwe lokwandisa impilo yezingxenye, izembozo ze-silicon carbide zinikeza ukuqina okungenakuqhathaniswa kanye nokuqina kwezinga lokushisa, okwenza zisebenziseke kahle isikhathi eside. Ngokukhetha indawo embozwe nge-silicon carbide, izimboni ziyazuza ekwehleni kwezindleko zokulungisa, ukuthembeka kwemishini okuthuthukisiwe, kanye nokusebenza kahle okuthuthukisiwe.

Kungani Kufanele Ukhethe AMANDLA E-VET?

I-VET ENERGY ingumkhiqizi ochwepheshe kanye nefektri yemikhiqizo yokumboza i-silicon carbide eShayina.
