I te urunga atu ki te ao ahumahi hou, ka kitea tonutia te aroaro o tētahi momo rauemi motuhake – kāore i te kanapa pērā i ngā konganuku, kāore hoki i te māmā pērā i ngā kirihou, engari ka tautoko puku i te mahi a te ahumahi hou. Koinei te whānau uku ahumahi, he rōpū rauemi kore-konganuku kore-waro e mōhiotia ana mō ō rātou āhuatanga motuhake.
I. Ngā "mema whetu" o te whānau uku ahumahi
I roto i te whānau uku ahumahi, he maha ngā mema e tino kitea ana: He rite ngā uku Alumina ki te tuakana pono, e whakawhirinaki ana ki te ātete pai ki te whakamarumaru me te waikura, ā, he mea nui ki ngā wāhanga hiko me ngā taputapu matū; He rite ngā uku Silicon nitride ki ngā kaitākaro mama, he pakeke rite ki ngā uku me te pakari o ngā konganuku, e whakaatu ana i te mahi pai i roto i ngā peera me ngā taputapu tapahi; He rite ngā uku Zirconia ki ngā kaihoahoa ahua, ehara i te mea he kanapa rite ki te pērara anake engari kei a rātou hoki te hangarau pango o te "whakapakaritanga huringa ā-wāhanga", e tino paingia ana i roto i ngā niho rūpahu me ngā wāhanga tika.
Tuarua.Ngā uku karawiti siliconTe toa whānui i te ao ahumahi
I roto i tēnei whānau, ka taea te kī ko ngā uku silicon carbide te toa tūturu mō ngā āhuatanga katoa. I hangaia tuatahitia tēnei uku motuhake i hangaia mai i ngā huānga silicon me te waro e te tangata i te tau 1905, ā, kua pakaru tonu ngā rekoata mahi a ngā rauemi ahumahi. He rite ki te whakangungu rakau i hangaia ki te taimana, me te pakeke Mohs tae atu ki te 9.5, ko te tuarua anake i te taimana tonu; he rite ki te pukupuku i hangaia mai i ngā pereki ātete, ka taea te tu atu i te 1350℃ o te tunu wera nui.
I roto i te awheawhe whakarewa, ka tautokona e ngā oko uku silicon carbide i hangaia ki te oumu te tinei i ngā pereki maitai; i roto i ngā paipa matū, ka huri hei kaitiaki ātete-waikura, ka roa ake te ora o ngā paipa; i runga i ngā raina whakaputa haurua-ira, he kōwhiringa pai hoki mō te peera tika; he mea whakamiharo ake, he mea tino pai tēnei rauemi taumaha, ā, ka kitea tōna tūranga i roto i te mara o te marara wera hiko.
III. Te panonitanga me te whānautanga hou i kawea mai e te hangarau
Kua whakakahangia e te hangarau hou ngā uku silicon carbide ki te ora hou. Mā te hangarau nanomodification, kua whakapakarihia e ngā kaipūtaiao tōna pakari; mā te whakamahi i te hangarau tā 3D, ka taea te hanga i ngā wāhanga āhua uaua e rite ana ki ngā mahi toi. I roto i te taiwhanga o tā mātou kamupene, kei te ako ngā miihini i ngā tikanga sintering silicon carbide, mā te whakamahi i te hangarau sintering matatau hei whakatutuki i ngā whakaritenga hua a ngā kiritaki me te whakapai tonu i te mahi a ngā hua uku silicon carbide, kia taea ai e rātou te urutau ki ngā āhuatanga mahi uaua ake.
Mai i te ahumahi tuku iho ki te hangarau matatau, kei te tuhi pakiwaitara hou a Industrial Ceramics. Hei kaiwhakarato ratonga hangarau e tohunga ana ki ngā uku silicon carbide, e whakapau kaha ana mātou ki te whakarato i ngā otinga ritenga. Ahakoa ko te tukatuka i ngā wāhanga āhua motuhake me ngā whakaritenga motuhake, ko te hoahoa rānei i ngā otinga tono mō ngā āhuatanga mahi tino uaua, ka kitea e mātou he tautoko ngaio i konei.
