O le a le mea e ufiufi ai le silicon carbide?

Silicon carbide ufiufi,e masani ona taʻua o le SiC coating, e faʻatatau i le faʻagasologa o le faʻaogaina o se lapisi o le silicon carbide i luga o luga e ala i metotia e pei ole Fua Faʻamaʻi (CVD), Vapor Deposition (PVD), poʻo le vevela vevela. O lenei fa'aluega sima carbide silicon e fa'aleleia atili ai mea o lo'o i luga ole mea'ai eseese e ala i le tu'uina atu o mea fa'apitoa e tete'e ai, mautu fa'amama, ma le puipuiga o le pala. O le SiC e lauiloa mo ona uiga mataʻina faaletino ma vailaʻau, e aofia ai le maualuga o le liusuavai (pe tusa ma le 2700 ℃), matua maaa (Mohs scale 9), sili atu le pala ma le faʻamaʻiina o le faʻamaʻi, ma le faʻaogaina o le faʻaogaina.

Fa'amanuiaga Autu ole Silicon Carbide Coating ile Alamanuia Talosaga

Ona o nei foliga, faʻapipiʻi carbide silicon e faʻaaogaina lautele i fanua e pei o le aerospace, meafaigaluega o auupega, ma le gaosiga o le semiconductor. I si'osi'omaga ogaoga, aemaise lava i totonu ole 1800-2000 ℃ laina, SiC faʻapipiʻi faʻaalia le faʻamaualuga faʻamautu faʻamaʻi ma le faʻafefeteina, ma faʻamaonia ai mo le maualuga o le vevela. Ae ui i lea, o le silicon carbide na o ia e leai se faʻatonuga faʻatulagaina e manaʻomia mo le tele o talosaga, o lea e faʻaaogaina ai metotia faʻapipiʻi e faʻaogaina ai ona uiga faʻapitoa e aunoa ma le faʻafefeina o le malosi o vaega. I le gaosiga o le semiconductor, elemene faʻapipiʻiina karbide silicon e maua ai le puipuiga faʻalagolago ma le mautu o le faʻatinoga i totonu o meafaigaluega faʻaaogaina i le MOCVD.

Metotia masani mo Silicon Carbide Sauniuniga Ufu

Ⅰ● Fa'aofuofu Ausa Fa'ama'i (CVD) Silicon Carbide Coating

I lenei metotia, e faʻapipiʻi ai SiC coatings e ala i le tuʻuina o substrates i totonu o se potu tali, lea e galue ai le methyltrichlorosilane (MTS) o se mea muamua. I lalo o tulaga fa'atonutonu-e masani lava 950-1300°C ma le mamafa mamafa-o le MTS e fa'aleagaina, ma fa'aputu i luga o le pito i luga. O lenei faiga faʻapipiʻi CVD SiC e faʻamautinoaina se faʻapipiʻi mafiafia, toniga ma faʻapipiʻi lelei, lelei mo faʻaoga maualuga i semiconductor ma aerospace vaega.

Ⅱ● Metotia o le Liua muamua (Polymer Impregnation and Pyrolysis – PIP)

O le isi auala silicon carbide spray coating lelei o le auala muamua liua, lea e aofia ai le faatofuina o le faataitaiga muai togafitia i se vaifofo sima precursor. A maeʻa ona faʻamama le tane faʻamaʻi ma faʻamalosi le ufiufi, e faʻavevela le faʻataʻitaʻiga, e oʻo atu ai i le faʻapipiʻiina o le carbide silicon i luga o le malulu. O lenei metotia e fa'amanuiaina mo vaega e mana'omia ai le mafiafia o le fa'aofuofu toniga ma fa'aleleia atili le tete'e o le ofuina.

Meatotino Faaletino o le Silicon Carbide Coating

Silicon carbide coatings o loʻo faʻaalia ai meatotino e faʻamaonia ai mo le manaʻomia o mea tau pisinisi. O nei meatotino e aofia ai:

Amioga vevela: 120-270 W/m·K
Coefficient o le fa'alauteleina o le vevela: 4.3 × 10^^(-6)/K (i le 20~800℃)
Tete'e eletise: 10^⁵– 10^⁶Ω·cm
Malosi: Mohs fua 9

Talosaga o le Silicon Carbide Coating

I le gaosiga o le semiconductor, fa'apipi'i carbide silicon mo le MOCVD ma isi fa'agasologa o le vevela e puipuia ai meafaigaluega taua, e pei o reactors ma susceptors, e ala i le ofoina atu uma o le maualuga o le vevela ma le mautu. I le aerospace ma le puipuiga, o lo'o fa'aogaina ai le sima carbide silicon coatings i vaega e tatau ona tatalia a'afiaga maualuga ma siosiomaga pala. E le gata i lea, e mafai fo'i ona fa'aoga le vali carbide silicon po'o mea fa'apipi'i i masini fa'afoma'i e mana'omia ai le tumau i lalo ole faiga ole fa'amama.

Aisea e filifili ai le Silicon Carbide Coating?

Faatasi ai ma se faʻamaumauga faʻamaonia i le faʻalauteleina o le ola o vaega, faʻapipiʻi carbide silicon e maua ai le tumau e le mafaatusalia ma le mautu o le vevela, ma faʻatau ai mo le faʻaaogaina umi. E ala i le filifilia o le silicon carbide coated surface, e manuia ai pisinisi mai le fa'aitiitia o tau o le tausiga, fa'aleleia atili le fa'atuatuaina o meafaigaluega, ma le fa'aleleia atili o galuega.

Aisea e Filifilia ai le VET ENERGY?

VET ENERGY o se tagata gaosi tomai faʻapitoa ma fale gaosi oloa faʻapipiʻi carbide silicon i Saina. O oloa faʻapipiʻi SiC autu e aofia ai le faʻavevela faʻavela keramika carbide,CVD Silicon Carbide Coating MOCVD Susceptor, MOCVD Graphite Carrier ma le CVD SiC Coating, SiC Coated Graphite Base Carriers, Silicon Carbide Coated Graphite Substrate mo Semiconductor,SiC Coating/Coated Graphite Substrate/Tray mo Semiconductor, CVD SiC fa'apipi'i Carbon-carbon Composite CFC Va'a Limu. VET ENERGY ua tuuto atu i le tuʻuina atu o tekinolosi faʻatekonolosi ma fofo oloa mo le alamanuia semiconductor. Matou te faʻamoemoe faʻamaoni e avea ma au paaga umi i Saina.
