Pereti Ātete Warowaihā Silicon
Pereti ātete karawiti siliconHe pereti arai oumu tēnei, he tino ātete ki te ahi me te kakahu. He maha ngā wā e whakamahia ana i roto i ngā taiao mahi e kawe ana, e whakawhiti ana hoki i te wera me ngā matū i raro i te pāmahana teitei, te pēhanga teitei me ngā āhuatanga waikura matū. Ko ngā pereti whakatakoto silicon carbide he mea hanga te nuinga mai i ngā rauemi silicon carbide me te silicon nitride, he nui te kiato papatipu me te pāmahana ātete ahi, he iti te kawe wera, ā, kāore e ngāwari ki te pā ki te tohatoha pāmahana o te taputapu.
Ngā Tukanga Whakaputa:OSiC/SSiC/NSiC/SiC/RBSiC(SiSiC)/RSiC.
Ngā Ahu/Āhua:Mā te miihini CNC ka taea te whakamahi i tētahi rahi (mōrahi 1200×800mm) me te āhua (tapawhā hāngai, porowhita, tapawhā motuhake).
Te Hanga Tuitui:Whakaritea ngā kaihoko here, ngā huringa whakawera, me ngā maimoatanga mata kia rite ki ō tawhā tukanga.
I muri i te Hokonga:Te kōrero hangarau, te aratohu tāutanga.
Ngā Āhuatanga:
Te ātete ahi me te ātete kakahu:Ka taea e ngā pereti whakatakoto karawiti silicon te mahi pumau i raro i ngā āhuatanga pāmahana teitei, pēhanga teitei me te waikura matū, ā, he tino ātete ki te ahi me te kakahu.
Te mahi ārai-waikura:Ka taea e ia te mahi pumau i roto i te whakahāngai me te whakaiti i ngā āhuarangi, ā, ka taea e te maha o ngā hurihanga te neke atu i te 500-1000 ngā wā.
Te kaha pēhi me te kaha piko o te pāmahana teitei:He kaha teitei, he ātete pai hoki ki te pēhanga, ā, ka taea te whakamahi mō te wā roa i te pāmahana teitei me te kore e hurihanga.
Ātete ki te whakamatao tere me te whakamahana:He pai tōna ātete ki te whakamatao me te whakamahana tere, ā, kāore e ngawari te pakaru i te wā e whakamahia ana. He whānuitanga pāmahana whakahaere: ka taea te whakamahi i waenga i te 800℃-1400℃.
Pereti karawiti silicon me te paninga aluminaKa taea te whakaiti i te kakahu o ngā rauemi, me te whakaroa i te roa o te mahi mā te hanga i tētahi paparanga tiaki o te alumina ki runga i te mata o te silicon carbide. I taua wā anō, ka taea e te ātete waikawa me te kawakore o te alumina te aukati i te mimiti o te silicon carbide e ngā pāpāho o waho, me te whakapai ake i te ātete waikura o te rauemi. Hei tāpiri, he pai ngā āhuatanga whakamarumaru o te alumina, ka taea te wehe i te kawe iahiko, te kawe wera rānei, me te karo i te ngaronga o ngā āhuatanga hiko, wera rānei.
