I ngā horopaki ahumahi pāmahana teitei, ko te mahi a ngā wāhanga hanganga ka whakatau tika i te whai huatanga o te whakaputanga, te haumaru me te whakahaere utu.Ngā kurupae silicon carbide (SiC)kua puta ake hei kaiwhakarerekē i te kēmu, e whakakapi ana i ngā rauemi tuku iho pēnei i te maitai me te uku alumina ki ō rātou ātete tino pai ki te pāmahana teitei, te ātete ki te waikura me te pumau o te hanganga. I hangaia kia roa te mau me te urutau, ka tutuki i ā mātou kurupae SiC ritenga ngā hiahia ahumahi kanorau, ka tukuna he mahi pono i roto i ngā taiao tino uaua.
Ko ngā whakamahinga o ngā kurupae silicon carbide e horapa ana ki te whānuitanga o ngā ahumahi pāmahana teitei, ā, he mea nui ēnei hei wāhanga matua. Ko te nuinga o te wā, e whakamahia whānuitia ana hei hanganga pikaunga me te tautoko taonga oumu i roto i ngā oumu ahumahi, tae atu ki ngā oumu kauhanga, ngā oumu whakawhiti, ngā oumu roera me ngā oumu pere. Ka pikau ēnei kurupae i te taumaha o ngā hua i runga i ngā motuka oumu, ā, ka tautoko i ngā hanganga ātete tuanui oumu, kia mau ai te mahi ahakoa i raro i te tunu roa i ngā pāmahana tae atu ki te 1380℃. He tino pai mō ngā tukanga sintering i roto i ngā uku hangarau, te paura uku hiko, ngā taputapu parakore, ngā rauemi pai me te kino o te pākahiko lithium, me ngā ahumahi rauemi ātete.
Haunga ngā whakamahinga oumu, he tino pai ngā kurupae SiC i roto i ētahi atu āhuatanga e hiahiatia ana. Nā te ātete pai ki te waikura me te pumau matū, he mea pai mō te whakamahi i roto i ngā kohua hiko wera, te sintering maitai me ngā tukanga pakaru matū, ka ātete ki te pirau mai i te waikura me ngā hau waikawa. Hei tāpiri, nā te tino parakore me te kaha hanganga ka taea te whakamahi i roto i ngā taputapu pāmahana teitei me te hanga semiconductor rererangi, hei tautoko i te whanaketanga o ngā ahumahi rautaki hou. Ki te whakatauritea ki ngā rauemi tuku iho, he 5-6 ngā wā roa ake te roa o te ora ratonga o ngā kurupae SiC, ka whakaiti nui i te auau tiaki me ngā utu whakakapinga.
E mārama ana mātou he rerekē ngā whakaritenga o ia kaupapa ahumahi, koia mātou e tuku atu ana i ngā otinga kurupae tapawhā silicon carbide kua whakaritea katoatia. Ka hipokina e tā mātou ratonga whakaritenga ngā āhuatanga nui katoa kia rite ki ō hiahia. Tuatahi, te whakaritenga ā-ahu: ka hangaia e mātou ngā kurupae me ngā rahi whakawhiti-wāhanga mai i te 30×30mm ki te 120×120mm me tua atu, me te matotoru o te pakitara ka taea te whakarerekē kia rite ki ō hiahia kawenga. Ka whakaratohia hoki e mātou he mīhini motuhake, pērā i ngā poka keri, ngā poka roa, ngā mokowā rānei, kia tino pai ai te whakaurunga ki ō taputapu o nāianei.
Tuarua, te whakaritenga rauemi: kei a mātou ngā kōwhiringa whakakoi tauhohenga (SiSiC/RSiC) me te whakakōwhai (RC-SiC), me te ihirangi SiC mai i te 85% ki te 99%, hei whakataurite i te mahi me te utu. Ka whakamatautauria ia kurupae kua whakaritea kia tino tika, tae atu ki te tika (≤1‰) me ngā whakamātautau kaha piko (tae atu ki te 280MPa i te 1200℃), kia mau ai te pono me te haumaru. Kei a mātou hoki ngā otinga takai kua whakaritea me te tuku kaipuke puta noa i te ao hei whakarite kia tae mai ō hua me te wā tika.
Hei kaihanga hua SiC ngaio, ka whakakotahi mātou i te hangarau sintering matatau me ngā tau o te wheako ahumahi hei tuku otinga ritenga kounga teitei. Ehara i te mea ka tutuki noa i ā mātou kurupae tapawhā silicon carbide ritenga ō hiahia mahi engari ka āwhina hoki ki te whakaiti i te whakapaunga pūngao me te whakapai ake i te pai o te whakaputa. Ahakoa e hiahia ana koe ki ngā rahi paerewa, ki ngā hoahoa kua whakaritea katoatia, ki ngā tohutohu hangarau rānei kua whakaritea mō tō ahumahi, whakapā mai ki a mātou i tēnei rā mō tētahi whakatau utu kore utu, kāore he herenga me te kōrero ngaio. Tukua ā mātou kurupae tapawhā SiC mahi teitei, kua whakaritea kia whakamanahia ō mahi pāmahana teitei—whakatairanga i te pumau, whakaiti i ngā utu, me te whakanui ake i ō kaha whakaputa.
