Ko tā mātou kaupapa matua he tipu hei kaiwhakarato auaha mō ngā taputapu matihiko me ngā taputapu whakawhitiwhiti kōrero hangarau teitei mā te tuku i te momo huatau, te hanga o te ao, me ngā āheinga whakatika mō ngā Takirere Pōro Graphite o Haina mō te Maimoatanga Wera. Ko tā mātou whāinga he waihanga i te āhuatanga toa-toa me ō mātou kiritaki. E whakapono ana mātou ko mātou te whiringa pai rawa atu māu. "Ko te Rongonui te Tuatahi, ko ngā Kiritaki te Tuatahi." "Kei te tatari mātou mō tāu patai."
Ko tā mātou kaupapa matua he tipu hei kaiwhakarato auaha mō ngā taputapu matihiko me ngā taputapu whakawhitiwhiti kōrero hangarau teitei mā te tuku i te momo huatau, te hanga o te ao, me ngā āheinga whakatika mōParaihe Karāpiti Haina, Ngā Kohuke me ngā Rauemi, E piri tonu ana mātou ki te pono, te painga tahi, te whanaketanga whānui. Whai muri i ngā tau maha o te whanaketanga me te whakapau kaha o ngā kaimahi katoa, kua tino pai te pūnaha kaweake, ngā otinga kawe kanorau, te tuku whānui ki ngā kiritaki, te kawe rererangi, te tereina o te ao me ngā ratonga kawe. He tūāpapa kotahi-mutu te rauemi mō ā mātou kiritaki!
Ngā mea whakakotahi waro / waro(e kiia nei i muri nei ko ""C / C, CFC rānei") he momo rauemi hiato e ahu mai ana i te waro, ā, e whakapakaritia ana e te muka waro me ōna hua (muka waro kua oti te hanga). He rite tōna āhua ki te waro, he rite hoki tōna kaha ki te muka waro. He pai ōna āhuatanga miihini, he ātete wera, he ātete waikura, he ārai waku, he pai hoki ōna āhuatanga kawe wera me te hiko.
CVD-SiCKo ngā āhuatanga o te paninga he hanganga ōrite, he rauemi kiato, he ātete pāmahana teitei, he ātete waikura, he parakore teitei, he ātete waikawa me te kawakore me te matū matū waro, me ngā āhuatanga ā-tinana me te matū pumau.
Ki te whakatauritea ki ngā rauemi karāpeti parakore-teitei, ka tīmata te karāpeti ki te waikura i te 400C, ka ngaro te paura nā te waikura, ka hua ake te parahanga taiao ki ngā taputapu taha me ngā rūma korehau, ka piki ake hoki ngā poke o te taiao parakore-teitei.
Heoi, ka taea e te paninga SiC te pupuri i te pumau ā-tinana me te matū i te 1600 nekehanga, he mea whakamahi whānuitia i roto i te ahumahi hou, inā koa i roto i te ahumahi semiconductor.
Ka whakaratohia e tā mātou kamupene ngā ratonga tukanga paninga SiC mā te tikanga CVD i runga i te mata o te karāpeti, te uku me ētahi atu rauemi, kia tauhohe ai ngā hau motuhake kei roto te waro me te silicon i te pāmahana teitei hei whiwhi i ngā ngota SiC parakore teitei, ka whakatakotoria ngā ngota ki runga i te mata o ngā rauemi pania, ka hanga he paparanga tiaki SIC. Ka piri pūmau te SIC i hangaia ki te turanga karāpeti, ka hoatu he āhuatanga motuhake ki te turanga karāpeti, nā reira ka hanga te mata o te karāpeti kia kiato, kia kore he porosity, kia ātete ki te pāmahana teitei, kia ātete ki te waikura me te ātete ki te waikura.
Ngā āhuatanga matua:
1. Ātete waikura pāmahana teitei:
He tino pai tonu te ātete ki te waikura ahakoa te teitei o te pāmahana ki te 1600 C.
2. Teitei o te parakore: i hangaia mā te whakatakotoranga kohu matū i raro i te āhuatanga whakapūkara pāmahana teitei.
3. Ātete ki te horo: he pakeke teitei, he mata kiato, he matūriki angiangi.
4. Ātete ki te waikura: waikawa, kawakore, tote me ngā matū waro.
