I roto i te ao hanga ahumahi, kei reira tonu ētahi wāhanga āhua motuhake e whakararuraru ana i ngā miihini – he paipa piko pea i roto i tētahi taputapu tika, he hanganga tautoko rānei me ngā awaawa uaua i roto i ngā taputapu pāmahana teitei. Ko ēnei wāhanga, e mōhiotia ana ko ngā "wāhanga tauhou," he uaua ki te hanga mai i ngā rauemi noa nā ō rātou āhua ahurei me ngā taiao mahi uaua. I ēnei rā, ko te silicon carbide, he rauemi āhua koretake, kei te whakarerekē marie i ngā mea katoa.
Ngā painga ā-roto o te rauemi tonu
Kia mārama ai he ahakarāhe siliconHe kaha ki te whakarite i ngā wāhanga koretake, me titiro tuatahi tātou ki tōna "hanganga". Kei roto i tēnei rauemi ngā "ira tino pai" e hiahiatia ana mō te hanga ahumahi: ko tōna pakeke te tuarua o te taimana, engari ka taea e ia te tu atu i ngā huringa pāmahana nui pērā i te konganuku; Ahakoa te waikura o ngā waikawa kaha me ngā kawakore, ka noho tonu ia me te kore e nekeneke; Ahakoa i ngā pāmahana teitei e tata ana ki te mata o te rā, ka taea tonu e ia te pupuri i tōna āhua pumau.
Nā tēnei huinga o ngā āhuatanga i taea ai e te silicon carbide te toa i te rārangi tīmatanga mai i te tīmatanga. Whakaarohia, ahakoa kei te raru tonu ētahi atu rauemi mēnā ka taea te hanga kia rite ki tēnei āhua, kei te whakaaroaro kē te silicon carbide me pēhea te whakapai ake. Nā tōna kaha me tōna pumau teitei ka taea e ngā kaihoahoa te karo i te whakarerekē i te hoahoa hanganga taketake tino pai kia uru ki ngā āhuatanga o te rauemi.
He 'makutu hanga' ngāwari, maha hoki ngā mahi
Kāore e ranea te whai rauemi pai anake. Hei huri i te silicon carbide ki ngā wāhanga āhua rerekē, me whai "makutu hanga" motuhake anō hoki. Kua mōhio ngā kaihangarau i ēnei rā ki ngā tikanga maha hei hanga i te silicon carbide kia "ngāwari":
He rite te hangarau pēhi matao isostatic ki te whakatakoto i tētahi "kākahu piri" motuhake ki runga i te paura silicon carbide. I raro i te pēhanga teitei, ka taea e te paura te piri ōrite ki ngā taipitopito katoa o te pokepokea ai, tae atu ki ngā kōhao uaua me ngā tauira ngawari ka taea te tārua tika. He rite te hangarau reera wai ki tētahi "maripi pokanga" ngāwari, e whakamahi ana i te rere wai tere-teitei hei ārahi i te reera me te whakairo i ngā hanganga uaua ki runga i te silicon carbide mārō, e kore ai e pakaru ngā rauemi, ā, ka taea te whakarite kia maeneene te mata.
Nā ēnei whanaketanga hangarau kua wetekina te karawiti silicon mai i te tapanga o ngā uku tuku iho ko "ngā pakarukaru, mārō, me te uaua ki te tukatuka". Pērā i te whakahāngai ki te uku rapa, ka taea e te hangarau o nāianei te hanga i te paura karawiti silicon i te tinana e tata ana ki tōna āhua whakamutunga, kātahi ka mahia te whakamahana pāmahana teitei hei hua mārō, ka whakaiti nui i te uaua o te tukatuka i muri mai.
Te Kawenga Pono i roto i ngā Taiao Tino Kino
He aha tātou me whakapau kaha ai ki te whakamahi i te silicon carbide hei hanga i ngā wāhanga koretake? Nā te mea he maha ngā wā, me mahi ēnei wāhanga āhua motuhake i roto i ngā taiao tino uaua.
I roto i te ipu waikura kaha o te tipu matū, ka taea e te paipa āhua-carbide silicon te ātete ki te waikura; I roto i te wāhi pāmahana teitei o ngā miihini rererangi, ka taea e ngā whāriki āhua-carbide silicon te tu atu ki ngā whakamātautau o ngā mano nekehanga; I roto i ngā taputapu tino tika mō te hanga haurua-ā-ira, ka taea e ngā wāhanga āhua-carbide silicon te pupuri i te tika pumau. I roto i ēnei āhuatanga, ehara i te mea kia ātaahua te āhua o te āhua motuhake, engari kia tutuki ai ngā mahi motuhake - tera pea hei whakangawari i te rere o te wai, hei tohatoha rānei i te wera kia ōrite.
Ko te ahurei o te silicon carbide kei roto i tōna kaha ki te whakatutuki i ngā whakaritenga hoahoa o ngā hanganga koretake, me te mahi pono i roto i ngā taiao tino kino mō te wā roa. Nā tēnei huinga o te pakari me te ngāwari kua waiho hei rauemi pai rawa atu i roto i te maha o ngā mara ahumahi.
Te heke mai o te hanga ritenga
I te whanaketanga o te hangarau hanga, kei te whakapai tonu te kaha whakaritenga o ngā wāhanga āhua-carbide silicon. Mai i ngā hanganga moroiti he torutoru mirimita ki ngā wāhanga nunui he maha mita te roa, mai i te piko ngāwari ki te polyhedra uaua, kei te pakaru te māramatanga taketake o te tangata mō ngā rauemi uku i te silicon carbide.
Mō ngā umanga, ko te tikanga o tēnei he nui ake ngā huarahi auaha – kāore e hiahiatia kia whakawhāitihia ngā whakaaro hoahoa mō ngā wāhanga paerewa, ā, ka taea hoki te whakarite i ngā otinga tino pai i runga i ngā hiahia tūturu. Mō te rāngai ahumahi katoa, ko te rongonui o ngā wāhanga āhua silicon carbide kei te akiaki i te whanaketanga o ngā taputapu ki te whai huatanga teitei ake, te roa, me te tika.
Mā tēnei rauemi makutu, me tōna "mana pakari" me tōna "toi pūkenga", ka hurihia ngā hoahoa koretake i runga i te mahere hei kaha mahi hei akiaki i te ahunga whakamua o te ahumahi.
