I roto i ngā tukanga tahu oumu pāmahana teitei, he mea nui te whiriwhiri i ngā taonga oumu tika mō te kounga hua, te whai huatanga o te whakaputa, me te whakahaere utu.Ngā whata oumu silicon carbide (SiC)kua puta ake hei otinga ārahi i te umanga, he pai ake te mahi i ngā whata cordierite me te alumina tuku iho i roto i te nuinga o ngā inenga mahi.
Mahi Pāmahana-Tiketike Kāore i te ōrite
He tino pai ngā whata oumu silicon carbide i roto i ngā taiao wera nui. Mā te pāmahana ratonga mōrahi tae atu ki te 1650°C (3002°F), ka mau tonu te hanganga pai me te pumau o ngā āhuatanga ina kore e pai ētahi atu rauemi. Nā te iti o te tauwehenga wera e whakarato ana i te ātete tino pai ki ngā ru wera, e āhei ai rātou ki te tu atu i ngā huringa whakamahana me te whakamatao tere me te kore e pakaru, e piko rānei. Mā tēnei pono ka whakaitihia te wā kore mahi, ka whakaitihia hoki ngā mate whakaputa mai i ngā taonga oumu kua pakaru.
Ngā Āhuatanga Mīhini Pai Rawa
He mea hanga mō ngā mahi ahumahi taumaha, he tino kaha, he ātete hoki ki te kakahu ngā whata oumu SiC. Nā te pakari me te matotoru o te papa, ka ātete rātou ki te pakaru mai i ngā kawenga hua taumaha me te whakahaere pinepine. Kāore i rite ki ngā momo ngoikore ake, ka mau tonu te papatahi me te āhua o ēnei whata i roto i ngā mano tini o ngā huringa tahu, kia mau tonu ai te tautoko mō ō hua. Mā te hanganga pakari ka taea te hanga i ngā hoahoa kōtaha angiangi (6-10mm te matotoru), te whakanui ake i te whakamahinga o te wāhi oumu me te whakanui ake i te kaha whakaputa puranga.
Te Whai Hua o te Pūngao me te Penapena Utu
Mā te kawe wera pai rawa atu o te silicon carbide ka tohatohahia te wera puta noa i te oumu, ka whakaitihia te whakapaunga pūngao me te whakapoto i ngā huringa tahu. Ka puta tika tēnei whai huatanga ki te whakaiti i ngā utu whakahaere. Hei tāpiri, mā te roa o te ora mahi o ngā whata SiC ka whakaitihia te auau whakakapinga me ngā whakaritenga tiaki, ka puta he hokinga pai ake i runga i te haumitanga ki te whakataurite ki ngā rauemi iti ake te pakari.
Ngā Taupānga Ahumahi Maha
He whānuitia te whakamahinga o ngā whata oumu silicon carbide puta noa i ngā rāngai hanga pāmahana teitei maha:
Ahumahi uku:He pai mō te tahu i ngā uku, te porcelain, me ngā uku matatau i roto i ngā oumu kauhanga me ngā oumu tere
Te Hanga Karāhe:He tino pai mō te whakamahana me te hanga hua karāhe
Ngā mea whakakoi me ngā mea whakakāhore:Whakamahia i roto i ngā tukanga sintering mō ngā rauemi mahi teitei
Te Whakarewa:He pai mō ngā wāhanga tautoko i roto i ngā oumu whakamahana
Ngā Otinga Ritenga mō ō Hiahia
Kei a mātou ngā whata oumu silicon carbide i roto i ngā momo hononga (hononga-nitride, whakakōata anō, hononga-tauhohenga) kia rite ki ō hiahia pāmahana me te āhuarangi. Kei te wātea ngā rahi me ngā āhua ritenga kia rite ki ngā rahi o tō oumu me ngā whakaritenga hua. Ka taea e tā mātou tīma tohunga te āwhina i a koe ki te whiriwhiri i te otinga whata SiC tino pai mō tō tono.
Ko te haumi ki ngā whata oumu silicon carbide kounga teitei he haumi ki te angitu roa o āu tukanga whakaputa pāmahana teitei. Wheakohia te rerekētanga o te mahi, te pakari, me te whai huatanga utu e tukuna ana e ngā taonga oumu SiC ārahi o te ahumahi.
