Kiriata Siliconized Vs. Ariki

Ko nga rauemi whakairoiro waro he whakaraeraetanga-a-tinana, he iti te kaha o te miiharo, te tino kaha o te mate-anti-kakahu, te umanga matū, te taonga, te taonga, nga taonga me etahi atu mara. Ko nga rauemi GRAWSITE he iti ake i te pai o te aro ki te aukati i te aukati me te aukati, he papanga miihini, he taputapu miihini e rua, a ka whakamahia i roto i te maha o nga tono.

He aha te mea whakamomori i te whakaahua?

Ko te whakairoiro siliconized he taonga whakahiato i te paparanga o te karaati silicon i pania ki te mata o te rauemi tuhi. Silicon Carbide matotoru o te 1 ~ 1.5mm, paparanga whakairo silicon me te papamahi i hono tata. Ko te uaua o te whakamomori whakairoiro ko te uaua o te sic, ko te tuarua anake ki te taimana, Boron Nitride, Boron Carbide, teitei ake i te uaua o te pustinete carbide me te konumohe konumohe.

Ko te whakamomori whakairoiro kaore anake te whakaraeraetanga i a koe ano i te papanga grable chamera, he taputapu hiko me te waiariki, engari he mea tino pai ki te aukati i te hau, engari he pai rawa atu heavy loads, high temperatures, and other demanding occasions, so the graphite silicide materials are more and more widely used in the field of sealing, friction, chemical industry, metallurgy, and aerospace and nuclear industry.

Te whakarite mo te whakamomori whakairoiro

E toru nga tikanga whakaputa matua mo te Whakaputa Whakaari Whakaari Maakahu Maaka (CVD), te tauhohenga kohurutanga matū (CVR) me te tikanga tauhohenga wairiro wai.

1. Te Whakatuturutanga Taputapu Taiao (CVD)) Tikanga

Ko te hau kei roto i te silicon me te waro na roto i te pāmahana nui o te waiariki, te whakaputa i te sic i tukuna ki te mata o te kaata whakairoiro. Rauemi mata mo te trichloromethylssilane (ch3sic3), silicon Tetrachloride, te hydrogen, te hauriri siliken me era atu. He whanui te whānuitanga o te whakahekenga pāmahana, mai i te 1175 ℃ ki te 1775 ℃. Ko te papanga o te tohu i hangaia e tenei tikanga he tino kiko, he matotoru whakakotahi, ko te matotoru whanui o te 0.1 ~ 0.3 mm, engari ko te whakakotahitanga o te miihini parakore, i te huringa tere o te pāmahana Ka raru te paparanga ki te ngoki, te tiiti.

2. Ko te tikanga o te tauhohenga raupaparorohiko (CVR)

Nga rauemi mata mo te paura kokonati me te onepu nui o te paura silica, i te tau 2000 ka puta te tauhohenga matū, te kohu i te tauhohenga. Ko te paparanga a SIC me te miihini konupuku i te rua kaore e kitea he atanga, he kaha te hononga o te pāmahana me te taumahatanga o te CVR. , No reira kei te pupuri tonu i te ahua o te kohinga waro. Heoi, ko te tikanga CVR ko te tauhohenga o te hauhautanga hau ki te waro, ka mau tonu te ahua o te waro, he mea tika kia whakauruhia nga tikanga o te hinu .

3. Ko te whakapae a te waihi

Ko tenei tikanga ko te ahua o te CVR. I raro i nga tikanga o te waatea, ka wera ki te 1700-19-1900 ℃, ka whakahoutia te waro ki te whakarewa i te wai whakarewa, ka uru te tauhohenga ki te whakaputa sic. 99.9999% o te rauemi hua mo te silicon parakore. Ko te matotoru o te papa matotoru o te 3.5 mm. I muri i te tauhohenga, kei te tipu o te waro, he 17% o te silicon koreutu hei whakakii i te turanga o te pore, na reira ka tino ngoikore te papaa. Heoi, ko te aroaro o te silicon koreutu e whakaheke i te aukati i te aukati me te whakaekenga o te waikawa nui o te whakairoiro.

Te rereketanga i waenga i te Giliconized Grak me te SIC

Ko te whakairoiro 1.silikonizziz (whakairoiro sikonized) he rauemi whakahiato i te papa o te karapa whakarewa kua pania ki te mata o te rauemi tuhi. Ko te uaua o te whakairoiro siciconized he pakeke te pakeke, he tuarua noa iho ki te taimana, Boron Nitride, Boron Carbide, nui atu i te tungsten Carbide, te konumohe konumohe me etahi atu uaua nui. Ka taea te whakamahi i te whakamomori Puka Ka taea te whakamahi hei waikawa phosphoric, te phosphorus apine me te waikawa waikawa hydrofluoric. I tua atu, ko te umanga semiconductor, hei tipuranga Etikaxial o te papa wera wera me te hanga i nga hononga taapiri, nga uaua o te ngakau.

2.Silicon Carbide (Sic) i hangaia mai i te onepu quartz, te kokina o te kowhatu rakau (ko te hanga kowhatu ranei (ko te whakaputa o te papaa silicon matomato me etahi atu rauemi matarohia. Ko te Carbide a Silicon ano hoki e noho ana i te ahua o te kohuke onge, Moassanite. Ko te Carbide Carbide hoki e mohiotia ana ano ko te koriri o te sivica. I roto i tenei ao, n, b me etahi atu mea-kore-taputapu miihini hangarau-hangarau mo te nuinga o te kohinga, ko te mea tino ohanga, ka kiia ko te onepu maitai koura, he kirikiri koura ranei. I tenei wa, ka wehea te hanga ahumahi o Haina ki te Ahuriri a Silicon Carbide me te matomato Carbide Carbide e rua nga momo, ko nga tioata hexagonal, he tohu motuhake o te 2840 ~ 3320kg / Mm2

He aha te mea whakamomori i te raima me te aha nga ahumahi e whakamahia ana?

Ko te whakairoiro siliconized he rauemi whakahiato e pa ana ki te paparanga Carbide Carbide i pania ki te mata o te papanga GRAPITE. Ko te uaua o te whakamomori whakairoiro ko te uaua o te sic, ko te tuarua anake ki te taimana, Boron Nitride, Boron Carbide, teitei ake i te tungsten carbide me te konumohe. Ka taea te whakamahi i te whakamomori Puka Ka taea te whakamahi hei waikawa phosphoric, waikawa phosphorite me te waikawa waikawa hydrofluoric. I tua atu, ko te umanga semiconductor, hei tipuranga Etikaxial o te papa wera wera me te hanga i nga hononga taapiri, nga uaua o te ngakau. Ko te Carbide Carbide e hangaia ana mai i te onepu o Quartz, te kokina o te raima (ko te tote ranei), ka tapiritia te tote ki te whakatipu i te papanga silicon matomato. Ko te Carbide a Silicon ano hoki e noho ana i te ahua o te kohuke onge, Moassanite. Ko te Carbide Carbide hoki e mohiotia ana ano ko te koriri o te sivica. I roto i tenei ao, n, b me etahi atu mea-kore-taputapu miihini hangarau-hangarau mo te nuinga o te kohinga, ko te mea tino ohanga, ka kiia ko te onepu maitai koura, he kirikiri koura ranei. I tenei wa, ka wehea te hanga ahumahi o Haina a Silicon Carbide kia rua nga momo pouaka whakaata pango, ko nga karaihe hexagonal, he 3340 ~ 3320kg / Mm2.

Ko te whakamomori whakairoiro hei ahua o te papanga whakahiato Carbides i whakaarahia ake nei, kaore i te tino uaua, ka whakakakahu i nga ahuatanga o te whakairoiro, te waikawa o te whakairoiro, te waiariki me te iti o te Te Whakahoahoa Thermal, ka taea te tono ki nga hiri miihini me etahi atu waahanga tino pai.

Ko te mata o te hiri o te hiri miihini kei roto i te hurihanga o te kohuru ka whakanohohia ki runga i te nohoanga, me te iti o te paoa, te ngoikoretanga o te waikore, me te mahi uaua me te kaha o te koriri ka tutuki i enei whakaritenga. Kei te whangangahia, i te wariu PV (te taumahatanga me te tere o te hua) tae atu ki te 147mpa-kowiri tira te kowhatu ahotea, me te uara o te mate pukupuku. m / s kahore he kino. Hei taapiri ka taea hoki te whakamahi mo te whakangungu rakau me nga hiri wai miihini miihini-nui me etahi atu hiri. Ka taea te whakamahi i te whakamomori Puka Ka taea te whakamahi hei waikawa phosphoric, waikawa phosphorite me te waikawa waikawa hydrofluoric. Hei taapiri, ko te ahumahi semiconductor, hei tipuranga epitaxial o te rongoa whakawera me te hanga i nga hononga toi, nga uaua o te ngakau, me te pakiaka niho.
