I te ao tino tika o te ahumahi hou, ko ngā panonitanga iti o ngā rauemi te nuinga o te wā e whakatau ana i te mahi tino pai o ngā taputapu.Ngā uku karawiti silicon, me ō rātou āhuatanga ā-tinana ahurei, kei te noho hei "kaitiaki pakari" tino nui i roto i te mara hangahanga teitei. Ko te ātete tino pai o te rauemi uku matatau ki te whakarerekētanga kei te tautuhi anō i ngā paerewa mahi mō ngā taputapu tino tika.
1, Waehere pūtaiao pakari
He rite te modulus elasticity o tētahi rauemi ki tētahi rūri hei ine i te pakari, hei whakatau tika i tōna kaha ki te ātete i te whakarerekētanga i raro i te taumahatanga. Ko te modulus elasticity o ngā uku silicon carbide he nui ake i te toru ngā wā i tō te maitai noa, e rite ana ki te anga whakakaha maitai i roto i ngā whare ina pēhia - ahakoa i raro i te kawenga kaha nui o ngā taputapu taumaha, ko te whakarerekētanga he 1/4 noa iho i tō ngā rauemi whakarewa.
I ahu mai tēnei pakari whakaharahara i te hanganga hononga honohono kaha i roto i te rauemi. He hononga piripono kei ia ngota waro ki ngā ngota silicon e whā mā roto i ngā taunekeneke kaha, ka hanga he hanganga tioata whatunga toru-ahu. Ina mahi ngā kaha o waho, ka taea e tēnei hanganga whatunga pumau te whakamarara i te ahotea me te whakahaere i te whakarerekētanga i roto i te awhe maikoromita. I roto i ngā mara pēnei i ngā papaaho whatu tika me ngā taputapu hanga semiconductor kāore e aro ki te whakarerekētanga, ka noho tēnei āhuatanga hei kī ki te whakarite i te tika.
2, Ko te rapunga whakaaro o ngā rauemi e whakakotahi ana i te pakari me te ngāwari
Ehara i te mea he tino pakari noa iho ngā uku karāhe silicon, engari he tino whakamiharo hoki te mahi whānui:
1. Pakari engari kāore e pakarukaru: Ko tōna kaha piko he nui ake i te maitai motuhake, ā, ahakoa i raro i te pēhanga e rite ana ki te pēhanga o te arewhana pakeke e tū ana i runga i te waewae kotahi (tata ki te 400MPa), ka taea tonu e ia te pupuri i te hanganga pumau. Mā tēnei huinga o te kaha teitei me te pakari teitei ka whakatauhia te raruraru ahumahi o te pakarukaru o ngā uku tuku iho.
2. Te pumau o te wera, pērā i te maunga: Ko te tauwehenga whānui wera o te rauemi he 1/4 noa iho i tērā o te maitai, ā, he iti noa te rerekētanga o te rahi i roto i te rerekētanga pāmahana o te 200 ℃. I te whakakotahitanga me tōna kawe wera pai rawa atu, ka taea e ia te whakataurite tere i ngā pikinga pāmahana me te karo i te kohikohinga o ngā whakarerekētanga i puta mai i te ahotea wera.
3. Kore e rerekē te āhua: I raro i te ahotea tonu, e rua ngā whakarea o te iti iho o te tere ngoki o te silicon carbide i tērā o ngā rauemi whakarewa. Ko te tikanga o tēnei ahakoa ka tukuna ki te kawenga kotahi mō ngā tau tekau, ka taea tonu te whakahaere i ōna huringa āhua i raro i te rohe kitenga taputapu.
3, Uara hangarau pakari
Ko tēnei kaha whakamiharo ki te ātete i te whakarerekētanga o te āhua kei te waihanga i ngā āheinga ahumahi hou:
I roto i ngā pūnaha whatu amiorangi, me whakarite kia mau tonu te papatahi o te whakaata i te taumata nanometer ahakoa ngā rerekētanga pāmahana tino nui o te wāhi.
Kia mau ki te tika o te tūnga i raro i te maikorone o te tūāpapa nekehanga o ngā taputapu tukatuka angiangi haurua-haurua i te wā e whakamahia ana i te tere tiketike.
Kia mau tonu te pumau āhuahanga o te hanganga hiri o te rūma pēhanga o ngā taputapu tūhura moana hohonu ahakoa i raro i te pēhanga wai taumata kiromita.
Ka hurihia e mātou tēnei painga rauemi hei whakataetae hangarau mā roto i ngā tukanga auaha: te whakamahi i ngā tikanga hanga matatau hei whakarei ake i te matotoru o ngā rauemi; Mā te whakamahi i ngā hangarau patent matatau, ka whakarei ake te pakari me te pupuri tonu i te tino pakari. Ka whakamatautauria ia puranga rauemi kia tino tutuki ai, kia hipa ake rānei i ngā whakaritenga a te kiritaki.
I tēnei rā, i te neke haere o te hanga tino tika ki te taumata nano, kei te whakamāramahia e ngā uku silicon carbide te kaupapa matua o te ahumahi hou me tōna "whakaaro pakari" - te whakamahi i te pumau tuturu o ngā rauemi hei tautoko i ngā āheinga mutunga kore o te hanga. Ko tēnei putanga hangarau, e whakaatu ana i te whakaaro nui o te pūtaiao rauemi, ka haere tonu te wero i te auahatanga o te "whakamahi i te pakari hei wikitoria i te ngāwari" ki te hanga taputapu teitei.
