I-CVD (Chemical Vapor Deposition) iyindlela evame ukusetshenziswa yokulungisa i-silicon carbide coatings.I-CVD silicon carbide coatingszinezici eziningi zokusebenza ezihlukile. Lesi sihloko sizokwethula indlela yokulungiselela i-CVD silicon carbide coating kanye nezici zayo zokusebenza.
1. Indlela yokulungiselela yeI-CVD silicon carbide coating
Indlela ye-CVD iguqula izanduleli zegesi zibe izimbotshana eziqinile ze-silicon carbide ngaphansi kwezimo zokushisa eziphezulu. Ngokusho kwezandulela ezihlukene zegesi, ingahlukaniswa ngesigaba segesi i-CVD kanye nesigaba se-liquid CVD.
1. Isigaba se-Vapor CVD
I-Vapor phase CVD isebenzisa izandulela zegesi, ngokuvamile i-organosilicon compounds, ukufeza ukukhula kwamafilimu e-silicon carbide. Izinhlanganisela ze-organosilicon ezivame ukusetshenziswa zifaka i-methylsilane, i-dimethylsilane, i-monosilane, njll., akha amafilimu e-silicon carbide kuma-substrates ensimbi ngokuhambisa izandulela zegesi emakamelweni okusabela asezingeni eliphezulu. Izindawo zokushisa eziphakeme ekamelweni lokuphendula ngokuvamile zikhiqizwa ukushisa okufakwayo noma ukufudumeza okuphikisayo.
2. I-CVD yesigaba samanzi
I-CVD yesigaba se-Liquid isebenzisa i-precursor ye-liquid, ngokuvamile i-solvent ephilayo equkethe i-silicon kanye ne-silanol compound, eshiswayo futhi ikhishwe ekamelweni lokuphendula, bese kwakhiwa ifilimu ye-silicon carbide ku-substrate ngokusebenzisa ukusabela kwamakhemikhali.
2. Izici zokusebenza zeI-CVD silicon carbide coating
1.Ukusebenza okuhle kakhulu kwezinga lokushisa eliphezulu
I-CVD silicon carbide coatingszinikeza ukuzinza okuhle kakhulu kwezinga lokushisa eliphezulu kanye nokumelana ne-oxidation. Iyakwazi ukusebenza ezindaweni ezishisayo futhi ingamelana nezimo ezibucayi emazingeni aphezulu okushisa.
2.Izakhiwo ezinhle zemishini
I-CVD silicon carbide coatinginobulukhuni obuphezulu kanye nokumelana okuhle kokugqoka. Ivikela ama-substrates ensimbi ukuthi angagugi futhi angagqwali, anwebe impilo yesevisi yezinto ezibonakalayo.
3. Ukuzinza kwamakhemikhali okuhle kakhulu
I-CVD silicon carbide coatingsamelana kakhulu namakhemikhali avamile njengama-asidi, ama-alkali nosawoti. Imelana nokuhlaselwa kwamakhemikhali nokugqwala kwe-substrate.
4. I-coefficient ye-friction ephansi
I-CVD silicon carbide coatingine-coefficient ephansi ye-friction kanye nezakhiwo ezinhle zokuzigcoba. Yehlisa ukungqubuzana nokuguga futhi ithuthukisa ukusebenza kahle kokusetshenziswa kwempahla.
5.Good conductivity ezishisayo
I-CVD silicon carbide coating inezakhiwo ezinhle zokushisa ezishisayo. Ingakwazi ukuqhuba ukushisa ngokushesha futhi ithuthukise ukusebenza kahle kokukhipha ukushisa kwesisekelo sensimbi.
6.Izakhiwo ezinhle kakhulu zokuvala ugesi
I-CVD silicon carbide coating inezindawo ezinhle zokuvala ugesi futhi ingavimbela ukuvuza kwamanje. Isetshenziswa kabanzi ekuvikelweni kokufakwa kwemishini kagesi.
7. Ukuqina nokwakheka okuguquguqukayo
Ngokulawula izimo phakathi nenqubo ye-CVD kanye nokuhlushwa kwe-precursor, ukushuba nokubunjwa kwefilimu ye-silicon carbide kungalungiswa. Lokhu kunikeza izinketho eziningi kanye nokuguquguquka kwezinhlelo zokusebenza ezihlukahlukene.
Ngamafuphi, i-CVD silicon carbide coating inokusebenza okuhle kakhulu kwezinga lokushisa eliphezulu, izakhiwo ezinhle kakhulu zemishini, ukuzinza okuhle kwamakhemikhali, i-coefficient ephansi yokungqubuzana, ukuguquguquka okuhle kwe-thermal kanye nezakhiwo zokufaka ugesi. Lezi zakhiwo zenza i-CVD silicon carbide coatings isetshenziswe kabanzi emikhakheni eminingi, kuhlanganise ne-electronics, optics, i-aerospace, imboni yamakhemikhali, njll.
