I roto i ngā pūnaha tahu me te kawe waka ahumahi pāmahana teitei,ngā roera silicon carbide (SiC)he wāhanga mahi-teitei kounga teitei e pai ake ana i ngā roera uku me te koranu alumina tuku iho. I hangaia hei tu atu i te wera nui, te ahotea miihini me te hau o te oumu waikura, he tino pakari, he pumau te āhua me te ātete ki te kakahu, ka waiho hei wāhanga matua e hiahiatia ana mō ngā oumu roera hou me ngā raina whakaputa. Mō ngā kaihanga o te ao e hiahia ana ki te whakaiti i te wā kore mahi, te whakaiti i ngā utu tiaki me te whakanui ake i te kounga hua, ko ngā roera SiC te whiringa pai mō ngā mahi pāmahana teitei.
He whānuitia te whakamahinga o ngā roera karawiti silicon puta noa i ngā ahumahi matua e tino hiahiatia ana. Ko te nuinga o ēnei roera he mea mahi mō te ahumahi uku, e tautoko ana i te hanga taera, taputapu horoi me ngā taputapu kai i roto i ngā rohe tahu oumu i te 1350℃-1450℃, e noho tika ana, kāore e piko, e poke rānei, hei whakaiti i ngā hapa o te hua. He mea nui hoki ēnei i roto i te hanga karāhe, e kawe ana i te karāhe papatahi me ngā karāhe kia maeneene i te wā e whakamahanahia ana, e hangaia ana hei ārai i ngā karawarawa. Ko ētahi atu whakamahinga matua ko te maimoatanga wera whakarewa mō te kawe i ngā wāhanga whakarewa taumaha, me te rāngai pūngao hou mō te hikohiko pākahiko lithium-ion me te whakamahana uku hiko, nā ō rātou āhuatanga rauemi parakore, kāore e poke.
E rua ngā momo roera SiC paerewa-ahumahi, he rerekētanga matua motuhake: ko te SiC kua whakakākanotia (RSiC) me te SiC kua honoa-tauhohenga (RBSiC), ia mea i hangaia mō ngā āhuatanga mahi motuhake.
Ka hangaia ngā Rōra SiC kua whakakōkītia anō mā te whakamahi i te whakamahana pāmahana teitei, kāore he wāhanga here, ka puta he hanganga SiC parakore. He ātete wera tino teitei mō te wā roa tae atu ki te 1600℃, he ātete ru wera pai rawa atu, ā, kāore he poke, he tino pai mō ngā uku kounga teitei, ngā rauemi hiko me ngā tono pūngao hou e tino hira ana te parakore me te manawanui pāmahana tino nui. He iti ake te kaha kawenga miihini engari he pumau pāmahana teitei kāore e taea te whakataurite.
Ko ngā Rōra SiC Hononga-Tauhohenga he mea hanga ki te wāhanga here silicon iti, e tuku ana i te kiato teitei ake, te kaha miihini kaha ake, me te mahi kawe kawenga taumaha pai ake. I hangaia mō te whakamahinga roa i te 1350℃-1450℃, te awhe pāmahana oumu tino noa, he iti te utu me te ātete ki te kakahu, ka waiho hei whiringa pai mō ngā raina whakaputa taera uku o ia rā, karāhe paerewa me te whakarewa whānui.
He rite ngā painga matua o ngā momo roera SiC e rua: he iti te rerekētanga i te pāmahana teitei, he kaha te ātete ki te waikura me te waikura, ā, he roa ake te ora ratonga i ngā roera tuku iho, he nui hoki te utu mō te whakakapinga tapahi me te mahi.
Ka whakaratohia e mātou he ratonga rōra SiC ritenga katoa e hāngai ana ki ō hiahia whakaputa. Ka āwhina tā mātou tīma i a koe ki te whiriwhiri i waenga i ngā momo kua whakahoutia me ngā momo kua honoa-tauhohenga i runga i te pāmahana mahi, te kawenga me te tahua, kātahi ka whakarite i ngā inenga matua: te diameter o waho/o roto, te roa katoa me te roa whai hua, me te miihini pito tika tae atu ki te necking, te slotting me ngā pito stepped kia tino uru ki tō oumu.
I te nekenga o te hanga ahumahi ki ngā tukanga pāmahana teitei ake, ko ngā roera silicon carbide tonu te otinga matua mō te hanga pumau, iti te utu. Mā te mahi pono me te whakaritenga ngāwari, ka āwhina i te arotau i ngā mahi me te whakapai ake i te whakataetae hua. Mena kei te hiahia koe ki ngā roera SiC kounga teitei, ki te aratohu ritenga ngaio rānei, ka tukuna e tā mātou tīma tohunga te tautoko rauemi, hoahoa me muri i te hoko katoa hei whakatutuki i ō hiahia kawe pāmahana teitei katoa.
