ʻO ka uhi ʻana o ka silicone carbide,ʻike maʻamau ʻia ʻo SiC coating, pili i ke kaʻina hana o ka hoʻopili ʻana i kahi papa o ka silicon carbide ma luna o nā ʻili ma o nā ʻano e like me Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), a i ʻole ka wai wela. Hoʻonui kēia silicon carbide ceramic coating i nā waiwai o ka ʻili o nā substrate like ʻole ma ka hāʻawi ʻana i ke kū kūʻokoʻa o ka lole, ke kūpaʻa wela, a me ka pale corrosion. ʻIke ʻia ʻo SiC no kāna mau waiwai kino a me ke kemika, me kahi helu heheʻe kiʻekiʻe (ma kahi o 2700 ℃), paʻakikī loa (Mohs scale 9), ʻoi aku ka maikaʻi o ka corrosion a me ka pale oxidation, a me ka hana ablation kūikawā.
Nā Pōmaikaʻi Koʻikoʻi o ka Silicon Carbide Coating ma nā noi ʻoihana
Ma muli o kēia mau hiʻohiʻona, hoʻohana nui ʻia ka uhi silicon carbide i nā kula e like me ka aerospace, nā mea kaua, a me ka hoʻoili semiconductor. Ma nā kaiapuni koʻikoʻi, ʻoi aku ma loko o ka laulā 1800-2000 ℃, hōʻike ʻo SiC coating i ke kūpaʻa wela a me ke kūpaʻa ablative, kūpono ia no nā noi wela kiʻekiʻe. Eia nō naʻe, nele ka silicon carbide wale nō i ka paʻa o ka hoʻolālā e pono ai no nā noi he nui, no laila ua hoʻohana ʻia nā ʻano uhi e hoʻohana i kāna mau waiwai kūʻokoʻa me ka ʻole o ka hoʻololi ʻana i ka ikaika o nā mea. I ka hana semiconductor, hāʻawi nā mea i uhi ʻia i ka silicon carbide i ka pale pono a me ka paʻa o ka hana i loko o nā mea hana i hoʻohana ʻia i nā kaʻina MOCVD.
Nā ʻano maʻamau no ka hoʻomākaukau ʻana i ka uhi ʻana o Silicon Carbide
Ⅰ● Hoʻopaʻa ʻia ʻo Chemical Vapor (CVD) Silicon Carbide Coating
Ma kēia ʻano, hoʻokumu ʻia nā uhi SiC ma ke kau ʻana i nā substrates i loko o kahi keʻena pane, kahi e hana ai ka methyltrichlorosilane (MTS) ma ke ʻano he precursor. Ma lalo o nā kūlana hoʻomalu-maʻamau 950-1300°C a me ke kaomi ʻino-ʻo ka MTS i ka decomposition, a waiho ʻia ka carbide silika ma luna o ka ʻili. ʻO kēia kaʻina hana hoʻopiʻi CVD SiC e hōʻoiaʻiʻo i kahi uhi paʻa, ʻaʻahu like me ka hoʻopili maikaʻi ʻana, kūpono no nā noi kiʻekiʻe i ka semiconductor a me nā ʻāpana aerospace.
Ⅱ● Ke Kaʻina Hoʻololi Precursor (Polymer Impregnation and Pyrolysis – PIP)
ʻO ke ala ʻē aʻe e pili ana i ka hoʻoheheʻe ʻana i ka silicon carbide spray coating, ʻo ia ke ʻano hoʻololi precursor, e pili ana i ka hoʻokomo ʻana i ka laʻana i hana mua ʻia i loko o kahi hopena ceramic precursor. Ma hope o ka hoʻomaʻemaʻe ʻana i ka pahu impregnation a me ke kaomi ʻana i ka uhi ʻana, ua wela ka hāpana, e alakaʻi ana i ka hoʻokumu ʻana o ka silicon carbide coating ma ka hoʻoilo. Hoʻohana ʻia kēia ʻano hana no nā ʻāpana e koi ana i ka mānoanoa o ka uhi ʻokoʻa a me ka hoʻoikaika ʻana i ke kūpaʻa ʻaʻahu.
Na Pono Kino o ka Silicon Carbide Coating
Hōʻike nā ʻāpana carbide silikon i nā waiwai i kūpono iā lākou no ke koi ʻana i nā noi ʻoihana. Aia kēia mau waiwai:
ʻO ka hoʻokō wela: 120-270 W/m·K
Coefficient o ka hoonui wela: 4.3 × 10^(-6)/K (ma 20~800 ℃)
Ke kū'ē uila: 10^5– 10^6Ω·cm
ʻO ka paʻakikī: Mohs scale 9
Nā noi o ka Silicon Carbide Coating
I loko o ka hana semiconductor, ka uhi ʻana o ka silicon carbide no MOCVD a me nā kaʻina hana wela kiʻekiʻe e pale i nā mea koʻikoʻi, e like me nā reactors a me nā susceptors, ma o ka hāʻawi ʻana i ka pale wela kiʻekiʻe a me ke kūpaʻa. I ka aerospace a me ka pale, ua hoʻopili ʻia nā ʻāpana seramika silicon carbide i nā mea pono e kū i nā hopena kiʻekiʻe a me nā wahi corrosive. Eia kekahi, hiki ke hoʻohana ʻia ka peʻa silicon carbide a i ʻole nā pale i nā lāʻau lapaʻau e pono ai ka lōʻihi ma lalo o nā kaʻina hana sterilization.
No ke aha e koho ai i ka Silicon Carbide Coating?
Me kahi moʻolelo i hōʻoia ʻia i ka hoʻolōʻihi ʻana i ke ola o nā mea, hāʻawi nā uhi silicon carbide i ka lōʻihi like ʻole a me ka paʻa o ka mahana, e hoʻolilo iā lākou i kumu kūʻai no ka hoʻohana lōʻihi. Ma ke koho ʻana i kahi ʻili silicon carbide i uhi ʻia, pōmaikaʻi nā ʻoihana mai ka hoʻemi ʻana i nā kumukūʻai mālama, hoʻonui i ka hilinaʻi o nā lako, a me ka hoʻomaikaʻi ʻana i ka hana.
No ke aha e koho ai i ka VET ENERGY?
ʻO VET ENERGY kahi mea hana ʻoihana a me ka hale hana o nā huahana silicon carbide coating ma Kina. ʻO nā huahana uhi SiC koʻikoʻi me ka silicon carbide ceramic coating heat,ʻO CVD Silicon Carbide Coating MOCVD Susceptor, MOCVD Graphite Carrier me CVD SiC Coating, ʻO nā mea lawe kumu kiʻi kiʻi i uhi ʻia ʻo SiC, Silicon Carbide Coated Graphite Substrate for Semiconductor,SiC Coating/Coated Graphite Substrate/Tray for Semiconductor, CVD SiC Coated Carbon-carbon Composite CFC Boat Mold. Hoʻokumu ʻo VET ENERGY i ka hoʻolako ʻana i ka ʻenehana holomua a me nā ʻōnaehana huahana no ka ʻoihana semiconductor. Manaʻolana mākou e lilo i hoa pili lōʻihi ma Kina.
