Chii chinonzi Silicon Carbide SiC Coating?

Silicon Carbide (SiC) coating ishanduko tekinoroji inopa chengetedzo yakasarudzika uye kuita munzvimbo dzepamusoro-tembiricha uye makemikari anoita. Uku kupfekedzwa kwepamusoro kunoiswa kune akasiyana zvinhu, zvinosanganisira graphite, ceramics, uye simbi, kusimudzira zvivakwa zvavo, zvichipa dziviriro yepamusoro kubva mukuora, oxidation, uye kupfeka. Iwo akasarudzika zvimiro zveSiC coatings, kusanganisira kuchena kwavo kwepamusoro, yakanakisa kupisa kwemafuta, uye kurongeka kwechimiro, inoita kuti ive yakanakira kushandiswa mumaindasitiri akadai semiconductor kugadzira, aerospace, uye yakakwirira-inoshanda yekudziya tekinoroji.

 

Zvakanakira zvesilicon carbide coating

SiC coating inopa akati wandei mabhenefiti ayo anoisa parutivi kubva kune echinyakare ekudzivirira machira:

• -High Density & Corrosion Resistance
• Iyo cubic SiC chimiro inovimbisa yakakwirira-density coating, zvakanyanya kunatsiridza corrosion kuramba uye kuwedzera hupenyu hwechikamu.
• -Kufukidzwa Kwakasarudzika kweMaumbirwo Akaoma
• SiC coating ine mukurumbira nekuvharika kwayo kwakanaka, kunyangwe mumakomba madiki mapofu ane hudzamu hunosvika 5 mm, ichipa ukobvu hweyunifomu kusvika pa30% pakadzika pakadzika.
• -Customizable Surface roughness
• Iyo yekupfekedza maitiro inochinjika, ichibvumira kusiyanisa kushata kwepamusoro kuti ienderane nezvinodiwa zvekushandisa.
• -High Purity Coating
• Inowanikwa kuburikidza nekushandiswa kweakanyanya-kuchena magasi, SiC coating inoramba yakanyatso chena, ine mazinga ekusachena kazhinji ari pasi pe5 ppm. Uku kuchena kwakakosha kune epamusoro-tech maindasitiri anoda kunyatsojeka uye kushoma kusvibiswa.
• -Thermal Kugadzikana
• Silicon carbide ceramic coating inogona kumira zvakanyanya tembiricha, ine tembiricha yekushanda inosvika 1600 ° C, ichivimbisa kuvimbika munzvimbo dzekupisa kwepamusoro.

 

Zvishandiso zveSiC Coating

SiC coatings inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana nekuda kwekuita kwavo kusingaenzaniswi munzvimbo dzakaoma. Zvikumbiro zvakakosha zvinosanganisira:

• -LED & Solar Indasitiri
• Iyo yekuputira inoshandiswawo kune zvikamu mu LED uye solar cell kugadzira, uko kuchena kwakanyanya uye kupisa kwekudzivirira kwakakosha.
• -High-Temperature Heating Technologies
• SiC-yakavharwa graphite uye zvimwe zvinhu zvinoshandiswa mukudziya zvinhu zvechoto uye mareactor anoshandiswa mune akasiyana maindasitiri maitiro.
• -Semiconductor Crystal Kukura
• Mune semiconductor crystal kukura, SiC coatings inoshandiswa kuchengetedza zvikamu zvinobatanidzwa mukukura kwesilicon uye mamwe semiconductor makristasi, achipa yakakwirira corrosion resistance uye kupisa kugadzikana.
• -Silicon uye SiC Epitaxy
• SiC coatings inoshandiswa kune zvikamu mu epitaxial kukura maitiro esilicon uye silicon carbide (SiC). Aya machira anodzivirira oxidation, kusvibiswa, uye kuve nechokwadi chemhando ye epitaxial layers, iyo yakakosha pakugadzirwa kwepamusoro-kuita semiconductor zvishandiso.
• -Oxidation uye Diffusion Maitiro
• SiC-coated components inoshandiswa mukuita oxidation uye diffusion maitiro, kwavanopa chipingamupinyi chinoshanda kurwisana netsvina isingadikanwi uye kuwedzera kuvimbika kwechigadzirwa chekupedzisira. Iwo machira anovandudza hupenyu hurefu uye kuvimbika kwezvikamu zvakafumurwa kune yakakwirira-tembiricha oxidation kana kupararira matanho.

 

Zvinhu zvakakosha zveSiC Coating

SiC coatings inopa huwandu hwezvivakwa zvinowedzera kushanda uye kusimba kweiyo sic yakavharwa zvikamu:

• -Crystal Mamiriro
• Iyo yekupfeka inogadzirwa neaβ 3C (cubic) kristarochimiro, icho chiri isotropic uye inopa yakanyanya kunaka kudzivirira ngura.
• -Density uye Porosity
• SiC coatings ine density ye3200 kg/m³uye kuratidza0% porosity, kuve nechokwadi chekuti helium inodonhedza-yakasimba kuita uye inoshanda ngura kuramba.
• -Thermal uye Magetsi Properties
• SiC coating ine yakakwira yekupisa conductivity(200 W/m·K)uye yakanakisa resistivity yemagetsi(1MΩ·m), zvichiita kuti zvive zvakanaka kune zvikumbiro zvinoda kupisa kutonga uye magetsi ekudzivirira.
• -Mechanical Simba
• Iine elastic modulus ye450 GPA, SiC coatings inopa hukuru hwemagetsi simba, kusimbisa kutendeseka kwemaitiro ezvikamu.

 

SiC silicon carbide coating process

Iyo SiC coating inoiswa kuburikidza neChemical Vapor Deposition (CVD), maitiro anosanganisira kuora kwekupisa kwemagasi kuisa akatetepa maSiC akaturikidzana pane substrate. Iyi nzira yekuisa inobvumira mazinga ekukura akakwira uye kutonga kwakaringana pamusoro pehukobvu, hunogona kubva kubva10 μm kusvika 500 µm, zvichienderana nekushandiswa. Maitiro ekupfekedza zvakare anovimbisa kufukidzwa kwakafanana, kunyangwe mune yakaoma geometries senge maburi madiki kana akadzika, ayo anowanzo kunetsa kune echinyakare nzira dzekupfeka.

 

Zvishandiso Zvinokodzera SiC Coating

SiC coatings inogona kuiswa kune dzakasiyana siyana zvinhu, zvinosanganisira:

• -Graphite uye Carbon Composites
• Graphite inzvimbo yakakurumbira yeSiC coating nekuda kwekunaka kwayo kupisa uye magetsi zvivakwa. SiC coating inopinda mukati meiyo graphite porous chimiro, ichigadzira chisungo chakasimudzirwa uye ichipa kuchengetedzwa kwepamusoro.
• -Ceramics
• Silicon-based ceramics yakadai seSiC, SiSiC, uye RSiC inobatsirwa kubva kuSiC coatings, iyo inovandudza kudzivirira kwavo kwekuora uye kudzivirira kupararira kwetsvina.

 

Sei Kusarudza SiC Coating?

Iyo yekupfeka yekumusoro inopa inochinja-chinja uye inodhura-mhinduro kune maindasitiri anoda kuchena kwepamusoro, corrosion resistance, uye kugadzikana kwemafuta. Kunyangwe iwe uri kushanda mu semiconductor, aerospace, kana yakakwirira-inoshanda kupisa zvikamu, SiC coatings inopa dziviriro nekuita kwaunoda kuchengetedza kushanda kwakanaka. Iko kusanganiswa kweakakwira-density cubic chimiro, inogoneka pamusoro pezvivakwa, uye kugona kupfeka yakaoma geometries inova nechokwadi chekuti sic yakavharwa zvinhu zvinogona kumira kunyangwe zvakanyanya kunetsa nharaunda.

Kuti uwane rumwe ruzivo kana kukurukura kuti silicon carbide ceramic coating inogona sei kubatsira yako chaiyo application, ndapotataura nesu.
