Chii chinonzi silicon carbide coating?

Kuputira nesilicon carbide,Inozivikanwa zvikuru seSiC coating, zvinoreva maitiro ekuisa silicon carbide pamusoro pezvinhu nenzira dzakadai seChemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), kana thermal spraying. Iyi silicon carbide ceramic coating inovandudza hunhu hwepamusoro hwezvinhu zvakasiyana-siyana nekupa simba rekudzivirira kupfeka, kugadzikana kwekupisa, uye dziviriro yengura. SiC inozivikanwa nehunhu hwayo hwepanyama nemakemikari, kusanganisira nzvimbo yakakwira yekunyunguduka (inenge 2700℃), kuomarara kwakanyanya (Mohs scale 9), kuramba ngura uye oxidation kwakanaka, uye kushanda kwakanaka kwe ablation.

Mabhenefiti Akakosha eSilicon Carbide Coating muMashandisirwo Emaindasitiri

Nekuda kwezvinhu izvi, silicon carbide coating inoshandiswa zvakanyanya munzvimbo dzakadai sendege, zvombo, uye semiconductor processing. Munzvimbo dzakanyanya, kunyanya mukati me1800-2000℃, SiC coating inoratidza kugadzikana kwekupisa uye kuramba kupisa, zvichiita kuti ive yakakodzera kushandiswa pakupisa kwakanyanya. Zvisinei, silicon carbide yoga haina hunhu hwayo hunodiwa pakushandiswa kwakawanda, saka nzira dze coating dzinoshandiswa kushandisa hunhu hwayo hwakasiyana pasina kukanganisa simba rezvikamu. Mukugadzira semiconductor, silicon carbide coating elements dzinopa dziviriro yakavimbika uye kugadzikana kwekushanda mukati memidziyo inoshandiswa muMOCVD processes.

Nzira Dzakajairika dzekugadzirira Silicon Carbide Coating

Ⅰ● Kuputira Silicon Carbide neKemikari (CVD)

Munzira iyi, machira eSiC anoumbwa nekuisa substrates mukamuri re reaction, uko methyltrichlorosilane (MTS) inoshanda se precursor. Pasi pemamiriro ezvinhu akadzorwa—kazhinji 950-1300°C uye kumanikidzwa kusina kunaka—MTS inoora, uye silicon carbide inoiswa pamusoro. Maitiro aya e CVD SiC coating anovimbisa kuti coating yakakora, yakafanana uye inonamatira zvakanaka, yakakodzera kushandiswa kwakanyatsojeka muzvikamu zve semiconductor uye aerospace.

Ⅱ● Nzira yekushandura precursor (Polymer Impregnation uye Pyrolysis - PIP)

Imwe nzira inoshanda yekuisa silicon carbide spray coating inzira yekushandura precursor, iyo inosanganisira kunyudza sampuro yakatogadzirwa kare mumushonga we ceramic precursor. Mushure mekupukuta tangi re impregnation uye kudzvanya coating, sampuro inodziiswa, zvichiita kuti silicon carbide coating iumbwe kana yatonhorera. Nzira iyi inodiwa kune zvinhu zvinoda ukobvu hwakafanana hwe coating uye kuramba kupfeka kwakawedzerwa.

Zvimiro zveSilicon Carbide Coating

Mapendi esilicon carbide anoratidza hunhu hunoita kuti akwanise kushandiswa mumaindasitiri. Hunhu uhwu hunosanganisira:

Kufambisa kwekupisa: 120-270 W/m·K
Kuwedzerwa kweThermal Coefficient: 4.3 × 10^^(-6)/K (pa 20~800℃)
Kudzivirira kweMagetsi: 10^⁵– 10^⁶Ω·cm
Kuoma: Mohs scale 9

Mashandisirwo eSilicon Carbide Coating

Mukugadzira zvinhu zvakaita semiconductor, silicon carbide coating yeMOCVD nedzimwe nzira dzekupisa kwakanyanya inodzivirira michina yakakosha, senge reactors nema susceptors, nekupa simba rekudzivirira kupisa kwakanyanya uye kugadzikana. Mundege nekudzivirira, silicon carbide ceramic coatings inoshandiswa kune zvinhu zvinofanirwa kutsungirira kukuvara nekukurumidza uye nharaunda dzinoparadza. Uyezve, pendi kana silicon carbide coatings zvinogona kushandiswawo pamidziyo yekurapa inoda kugara kwenguva refu pasi pemaitiro ekuchenesa.

Sei Uchifanira Kusarudza Silicon Carbide Coating?

Neruzivo rwakaratidza kuti zvinhu zvinogara kwenguva refu, machira esilicon carbide anopa kugara kwenguva refu uye kugadzikana kwekupisa, zvichiita kuti ashande zvakanaka kwenguva refu. Nekusarudza nzvimbo ine silicon carbide, maindasitiri anobatsirwa nekudzikira kwemari yekugadzirisa, kuvimbika kwemidziyo, uye kushanda zvakanaka.

Sei Uchifanira Kusarudza Simba reVet?

VET ENERGY inyanzvi yekugadzira uye fekitari yezvigadzirwa zvekuputira silicon carbide muChina. Zvigadzirwa zvikuru zvekuputira SiC zvinosanganisira silicon carbide ceramic coating heater,CVD Silicon Carbide Coating MOCVD Susceptor, MOCVD Graphite Carrier ine CVD SiC Coating, SiC Coated Graphite Base Carriers, Silicon Carbide Yakaputirwa Graphite Substrate yeSemiconductor,SiC Coating/Coated Graphite Substrate/Tray yeSemiconductor, CVD SiC Yakafukidzwa neCarbon-carbon Composite CFC Boat Mould. VET ENERGY yakazvipira kupa tekinoroji yepamusoro uye mhinduro dzezvigadzirwa kuindasitiri yesemiconductor. Tine tariro yechokwadi yekuve mubatsiri wako wenguva refu muChina.
