Ngā uku karawiti siliconHe rauemi matua ēnei i roto i te whānuitanga o ngā ahumahi nā ō rātou āhuatanga ahurei, tae atu ki te pakeketanga teitei, te iti o te mātotorutanga me te ātete wera pai rawa atu. Nā ēnei āhuatanga ka waiho te silicon carbide (SiC) hei whiringa pai mō ngā tono i roto i te miihini, te matū me te whakarewa, ngā oumu ahumahi me ngā taputapu whakamahana. Ka tirohia e tēnei tuhinga ngā tono maha o ngā uku silicon carbide, me te whakaatu i tō rātou hiranga i roto i ngā tukanga hanga me ngā tukanga ahumahi hou.
I roto i te ao hangarau miihini, kei te piki haere te whakamahinga o ngā uku silicon carbide nā te mea he tino pakari, he ātete hoki ki te kakahu. He tino pai ēnei rauemi mō te hanga i ngā wāhanga iti e ārai ana i te wera me ngā wāhanga kakahu e hiahia ana kia roa, kia pono hoki. Ka taea e te silicon carbide te tu atu ki ngā pāmahana teitei me te kore e whakapohehe, e ngaro rānei te hanganga, ā, he mea tino pai mō te whakamahi i roto i ngā mīhini mahi-teitei. I te mea kei te hiahia tonu te ahumahi ki ngā wāhanga whai hua me te roa, e matapaetia ana ka nui haere te tūranga o ngā uku silicon carbide i roto i te hangarau miihini.
Kua tino whai hua hoki ngā ahumahi matū me te whakarewa i ngā uku silicon carbide. He tino ātete ēnei rauemi ki te waikura, inā koa ki te rino rewa, te para me ngā konganuku kawakore. He mea nui tēnei āhuatanga i roto i ngā taiao ka pakaru ngā rauemi tuku iho, ka nui te utu mō te wā whakamutu me te tiaki. He mea nui, neke atu i te 65% o ngā oumu pupuhi nui o te ao e whakamahi ana i ngā rauemi silicon carbide e herea ana ki te silicon nitride hei rauemi tinana oumu. Ehara i te mea ka roa ake te ora o ngā oumu pupuhi mā te 20-40% anake, engari ka whakapai ake hoki i te pai o te mahi. Hei tāpiri, ka whakamahia hoki ngā uku silicon carbide hei arai oumu me ngā oko whakarewa mō te whakarewa whakarewa pērā i te konumohe, te parahi me te konutea, e whakaatu ana i tōna whakamahinga maha i roto i ngā tono pāmahana teitei.
I roto i ngā oumu ahumahi, he mea nui te mahi a ngā uku silicon carbide ki te whakapai ake i te mahi me te whai huatanga o te pūngao. Mā te whakamahi i ngā taonga oumu silicon carbide ka taea te whakaiti i te taumaha me te wāhi e hiahiatia ana, he mea tino pai tēnei mō ngā ahumahi pēnei i te ahumahi māmā, ngā rauemi hanga me ngā hikohiko. Mā te mama o ngā wāhanga silicon carbide ka āwhina i te whakapai ake i te whakamahinga pūngao nā te mea he iti ake te pūngao e hiahiatia ana hei whakamahana i te oumu. Hei tāpiri, mā te ātete pānga pai o ngā rauemi silicon carbide ka taea te piki tere ake o te pāmahana ahi, ka whakapai ake i te whai huatanga o te mahi oumu.
He mea nui hoki ngā uku karāhe silicon ki ngā momo taputapu whakamahana e whakamahia ana mō te whakawera, te whakarewa, me ngā rauemi whakamahana. Kua noho te whakamahana ā-korekore ki te hau hei tikanga pai i roto i ēnei tukanga nā te mea ka taea te whakapai ake i te pai o te wera me te whakaiti i ngā tukunga kino, pērā i ngā waikura hauota (NOx). Ko te whakamahinga o te karāhe silicon i roto i ēnei taputapu whakamahana ehara i te mea ka whakapai ake i te mahi engari ka tutuki hoki i ngā mahi a te ao ki te whakaiti i te pānga ki te taiao. I te whai a ngā ahumahi ki ngā otinga e pai ake ana ki te taiao, tera pea ka piki ake te hiahia mō ngā uku karāhe silicon mō ngā tono whakamahana.
Ko te maha o ngā mahi a ngā uku silicon carbide kei tua atu i ngā whakamahinga tuku iho, nā te mea kei te piki haere te whakamahinga i roto i ngā hangarau matatau. Hei tauira, i roto i te rāngai hiko, ka whakamahia te silicon carbide ki te hanga i ngā haurua-ira me ngā taputapu hiko. Ko te kaha o te kawe wera me te ārai hiko o te silicon carbide he mea tino pai mō ngā whakamahinga hiko auau-teitei me te pāmahana-teitei. I te mea kei te piki haere tonu te hiahia mō ngā wāhanga hiko whai hua me te pono, e matapaetia ana ka whai wāhi nui ngā uku silicon carbide ki te hanga hiko a meake nei.
Hei tāpiritanga, kei te tīmata ngā umanga rererangi me ngā umanga motuka ki te kite i te kaha o ngā uku karawiti silicon mō ngā wāhanga mama, kaha. Nā te kaha o te karawiti silicon ki te tu atu i ngā pāmahana tino kino me ngā taiao uaua, he mea ātaahua tēnei mō ngā tono pēnei i ngā mata tāpoi, ngā kōpae parai, me ētahi atu wāhanga nui. I te mea e whai ana ēnei umanga ki te whakapai ake i te whai huatanga o te wahie me te whakaiti i ngā tukunga, mā te whakauru i ngā uku karawiti silicon ki roto i ā rātou hoahoa ka tino whakapai ake i te mahi me te pumau.
Hei whakarāpopototanga, he whānui ngā whakamahinga o ngā uku silicon carbide, nā ō rātou āhuatanga ahurei me ngā painga mahi. Mai i te hangarau miihini ki te tukatuka matū, ngā oumu ahumahi me ngā hikohiko matatau, kua whakamātauhia ngā uku silicon carbide hei wāhanga nui o te hanga hou. I te haere tonu o te whanaketanga o te hangarau, ka piki ake te kaha o ngā uku silicon carbide ki te whai wāhi ki ngā otinga auaha me ngā mahi pumau. He mea whakamīharo te heke mai o ngā uku silicon carbide, ā, ko te rangahau me te whanaketanga tonu kei te whakatakoto i te ara mō ngā whakamahinga hou me te whakapai ake i te mahi i roto i ngā mara rerekē.
