Chii chinonzi silicon carbide coating?

Silicon carbide coating,inowanzozivikanwa seSiC coating, inoreva maitiro ekuisa chidimbu chesilicon carbide panzvimbo kuburikidza nenzira dzakadai seChemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), kana kupfapfaidza kupisa. Iyi silicon carbide ceramic coating inosimudzira zvimiro zvepasi zveakasiyana substrates nekupa yakasarudzika kupfeka kuramba, kugadzikana kwemafuta, uye kudzivirira ngura. SiC inozivikanwa nekutanhamara kwayo kwemuviri uye makemikari zvimiro, kusanganisira yakakwira kunyungudika (inenge 2700 ℃), kuomarara kwakanyanya (Mohs chiyero 9), yakanakisa ngura uye oxidation kuramba, uye yakasarudzika ablation performance.

Mabhenefiti Akakosha eSilicon Carbide Coating muIndasitiri Zvishandiso

Nekuda kweaya maficha, silicon carbide coating inoshandiswa zvakanyanya muminda senge aerospace, zvombo zvekushandisa, uye semiconductor kugadzirisa. Munzvimbo dzakanyanyisa, kunyanya mukati meiyo 1800-2000 ℃ renji, SiC coating inoratidza kudzikama kwemafuta uye ablative kuramba, zvichiita kuti ive yakakodzera kune yakanyanya-tembiricha application. Nekudaro, silicon carbide yega inoshaya kutendeseka kunodiwa kune akawanda maapplication, saka nzira dzekupfekedza dzinoshandiswa kuwedzera zvivakwa zvayo zvakasiyana pasina kukanganisa simba rechikamu. Mukugadzira semiconductor, silicon carbide yakavharwa zvinhu zvinopa chengetedzo yakavimbika uye kugadzikana kwekuita mukati memidziyo inoshandiswa muMOCVD maitiro.

Dzakajairwa Nzira dzeSilicon Carbide Coating Kugadzirira

Ⅰ● Chemical Vapor Deposition (CVD) Silicon Carbide Coating

Munzira iyi, SiC coatings inoumbwa nekuisa substrates mukamuri yekupindura, uko methyltrichlorosilane (MTS) inoshanda seyakatangira. Pasi pemamiriro ezvinhu anodzorwa-kazhinji 950-1300 ° C uye kudzvinyirira kwakashata-iyo MTS inopinda mukuora, uye silicon carbide inoiswa pamusoro. Iyi CVD SiC yekupfekedza maitiro inovimbisa kukora, kupfekedza yunifomu nekunamira kwakanaka, kwakanakira kushandiswa kwepamusoro-soro mu semiconductor uye zvikamu zvemuchadenga.

Ⅱ● Precursor Conversion Method (Polymer Impregnation uye Pyrolysis - PIP)

Imwe nzira inoshanda yesilicon carbide yekupfapfaidza yekuputira ndiyo nzira yekushandura, iyo inosanganisira kunyudza sampuli isati yagadziriswa mune ceramic precursor solution. Mushure mekutsvaira tangi yekumisikidza uye nekudzvanya iyo yekuputira, sampu inodziya, zvichitungamira kune silicon carbide yekuputira kuumbwa pakutonhora. Iyi nzira inofarirwa kune zvikamu zvinoda yunifomu yekupfekedza ukobvu uye inosimudzira kupfeka kuramba.

Zvenyama Zvimiro zveSilicon Carbide Coating

Silicon carbide coatings inoratidza zvivakwa zvinoita kuti ive yakanakira yekuda maindasitiri ekushandisa. Zvinhu izvi zvinosanganisira:

Thermal Conductivity: 120-270 W/m·K
Coefficient of Thermal Expansion: 4.3 × 10 ^^(-6)/K (pa20~800℃)
Electrical Resistivity: 10 ^⁵– 10…⁶Ω·cm
Kuoma: Mohs chikamu 9

Zvishandiso zveSilicon Carbide Coating

Mukugadzira semiconductor, silicon carbide coating yeMOCVD uye mamwe maitiro epamusoro-tembiricha inodzivirira midziyo yakakosha, senge reactor uye susceptors, nekupa zvese zvakakwirira-tembiricha kuramba uye kugadzikana. Mumuchadenga nekudzivirira, silicon carbide ceramic coatings inoiswa kune zvikamu izvo zvinofanirwa kumirisana nekumhanyisa-kumhanya uye nharaunda dzinoparadza. Uyezve, silicon carbide pendi kana machira anogona zvakare kushandiswa pazvishandiso zvekurapa zvinoda kusimba pasi pemaitiro ekubereka.

Sei Kusarudza Silicon Carbide Coating?

Iine rekodhi yakasimbiswa mukuwedzera hupenyu hwechikamu, silicon carbide coatings inopa kusimba kusingaenzaniswi uye kugadzikana kwekushisa, zvichiita kuti ive inodhura-inoshanda yekushandisa kwenguva refu. Nekusarudza silicon carbide yakavharwa pamusoro, maindasitiri anobatsirwa kubva mukudzikira kwemitengo yekugadzirisa, kuvimbika kwemidziyo, uye nekuvandudza kushanda nesimba.

Sei Kusarudza VET ENERGY?

VET ENERGY inyanzvi inogadzira uye fekitori yesilicon carbide coating zvigadzirwa muChina. Iyo huru SiC yekupfekedza zvigadzirwa zvinosanganisira silicon carbide ceramic coating hita,CVD Silicon Carbide Coating MOCVD Susceptor, MOCVD Graphite Carrier ine CVD SiC Coating, SiC Coated Graphite Base Carriers, Silicon Carbide Coated Graphite Substrate yeSemiconductor,SiC Coating/Coated Graphite Substrate/Tray yeSemiconductor, CVD SiC Yakaputirwa Carbon-carbon Inoumbwa CFC Boat Mold. VET ENERGY yakazvipira kupa tekinoroji yepamusoro uye zvigadzirwa mhinduro kune iyo semiconductor indasitiri. Tinovimba nemoyo wese kuva shamwari yako yenguva refu muChina.
