Iyini i-silicon carbide coating?

Ukufakwa kwe-silicon carbide,eyaziwa ngokuthi i-SiC coating, ibhekisela ohlelweni lokusebenzisa ungqimba lwe-silicon carbide ezindaweni ezingaphezulu ngokusebenzisa izindlela ezifana neChemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), noma isifutho esishisayo. Lesi sembatho se-silicon carbide ceramic sithuthukisa izakhiwo ezingaphezulu zama-substrates ahlukahlukene ngokunikeza ukumelana nokugqokwa okukhethekile, ukuqina okushisayo, nokuvikela ukugqwala. I-SiC yaziwa ngezici zayo ezivelele zomzimba namakhemikhali, okuhlanganisa indawo ephezulu yokuncibilika (cishe i-2700 ℃), ukuqina okwedlulele (isilinganiso se-Mohs 9), ukugqwala okuhle kakhulu nokumelana ne-oxidation, kanye nokusebenza okukhethekile kokukhishwa kwe-ablation.

Izinzuzo Eziyinhloko Ze-Silicon Carbide Coating ku-Industrial Application

Ngenxa yalezi zici, i-silicon carbide coating isetshenziswa kabanzi emikhakheni efana ne-aerospace, imishini yezikhali, kanye nokucubungula kwe-semiconductor. Ezimweni ezimbi kakhulu, ikakhulukazi phakathi kwebanga le-1800-2000 ℃, ukumbozwa kwe-SiC kukhombisa ukuzinza okubabazekayo okushisayo nokumelana nokushisa, okuyenza ilungele ukusetshenziswa kwezinga lokushisa eliphezulu. Kodwa-ke, i-silicon carbide iyodwa ayinakho ubuqotho besakhiwo obudingekayo ezinsizeni eziningi, ngakho-ke izindlela zokumboza zisetshenziswa ukuze kuthuthukiswe izakhiwo zayo eziyingqayizivele ngaphandle kokuyekethisa amandla engxenye. Ekwenziweni kwe-semiconductor, izakhi ezimbozwe nge-silicon carbide zinikeza ukuvikeleka okuthembekile nokuzinza kokusebenza ngaphakathi kwemishini esetshenziswa ezinqubweni ze-MOCVD.

Izindlela Ezivamile Zokulungiselela I-Silicon Carbide Coating

Ⅰ● I-Chemical Vapor Deposition (CVD) I-Silicon Carbide Coating

Kule ndlela, ukugqoka kwe-SiC kwenziwa ngokubeka ama-substrates ekamelweni lokuphendula, lapho i-methyltrichlorosilane (MTS) isebenza njengesandulela. Ngaphansi kwezimo ezilawulwayo-imvamisa i-950-1300 ° C nokucindezela okungalungile-i-MTS idlula ukubola, futhi i-silicon carbide ifakwe phezulu. Le nqubo yokumboza ye-CVD SiC iqinisekisa ukujiya, ukunamathela okufanayo okunamathelayo okuhle kakhulu, okulungele ukusetshenziswa okunembayo okuphezulu emikhakheni ye-semiconductor kanye ne-aerospace.

Ⅱ● Indlela Yokuguqula I-Precursor (I-Polymer Impregnation ne-Pyrolysis - i-PIP)

Enye indlela esebenzayo yokumboza isifutho se-silicon carbide yindlela yokuguqula eyandulelayo, ehlanganisa ukucwiliswa kwesampula eselashwe kusengaphambili kusixazululo sesandulela se-ceramic. Ngemva kokucwenga ithangi lokufaka i-impregnation kanye nokucindezela ukunamathela, isampula iyashiswa, okuholela ekwakhekeni kwe-silicon carbide enamathela lapho kupholisa. Le ndlela ithandwa ezingxenyeni ezidinga ukujiya kwe-uniform coating kanye nokumelana nokugqokwa okuthuthukisiwe.

Izakhiwo Zomzimba zeSilicon Carbide Coating

I-silicon carbide coatings ibonisa izakhiwo ezizenza zibe zilungele izicelo ezifunwa yizimboni. Lezi zakhiwo zihlanganisa:

I-Thermal Conductivity: 120-270 W/m·K
I-Coefficient of Thermal Expansion: 4.3 × 10^^(-6)/K (ku-20~800℃)
Ukumelana Nogesi: 10^⁵- 10^⁶Ω·cm
Ukuqina: Isilinganiso se-Mohs 9

Izicelo zeSilicon Carbide Coating

Ekwenziweni kwe-semiconductor, i-silicon carbide coating ye-MOCVD nezinye izinqubo zokushisa okuphezulu kuvikela imishini ebalulekile, njengama-reactors nama-susceptors, ngokunikeza kokubili ukumelana nokushisa okuphezulu nokuzinza. Kwi-aerospace nokuzivikela, i-silicon carbide ceramic coatings isetshenziswa ezingxenyeni okufanele zimelane nemithelela yesivinini esiphezulu kanye nezindawo ezigqwalile. Ngaphezu kwalokho, upende we-silicon carbide noma okokunamathela kungasetshenziswa emishinini yezokwelapha edinga ukuqina ngaphansi kwezinqubo zokuvala inzalo.

Kungani Khetha I-Silicon Carbide Coating?

Ngerekhodi elifakazelwe ekwandiseni impilo yengxenye, izimbobo ze-silicon carbide zinikeza ukuqina okungenakuqhathaniswa nokuzinza kwezinga lokushisa, okuzenza zingabizi kakhulu ukusetshenziswa kwesikhathi eside. Ngokukhetha indawo eboshwe nge-silicon carbide, izimboni ziyazuza ekwehleni kwezindleko zokulungisa, ukwethembeka okuthuthukisiwe kwemishini, kanye nokusebenza kahle okuthuthukisiwe.
