I roto i ngā mara hou pēnei i te hangarau haurua-ira, te pūngao hou, me te rererangi, he mahi nui tā te rauemi uku hina-pango.uku karāhe silicon– he rauemi he rite te pakeke ki te taimana, e whakarerekē ana i te āhua o te ahumahi hou nā tōna ātete ki te pāmahana teitei, te ātete ki te waikura me te kawe wera teitei. Engari kāore i te tino mōhiotia whānuitia, hei huri i te paura silicon carbide mārō hei taputapu tino tika, me whai tukanga "hanga pāmahana teitei" makutu.
I. Te Tukanga Sintering: Te Makutu Matua hei Huri i ngā Kōhatu hei koura
Ki te whakaritea te paura silicon carbide ki te jade kāore anō kia orohia, ko te tukanga sintering te tukanga matua hei hanga hei hua pai. Mā te hanga pāmahana teitei i te 800-2000℃, ka "ruru ringa" anō ngā matūriki paura iti-macron i te taumata atomika, ka hanga he tinana uku matotoru me te totoka. Ko ngā tukanga sintering rerekē, pērā i ngā tikanga whakairo rerekē, ka whakawhiwhia ki ngā rauemi ngā āhuatanga mahi ahurei:
1. Te whakawera i te pēhanga hauāwhio: Ko te "kohua puhoi i runga i te wera iti" tino tuku iho
Pērā i te hupa reka kua tunua puhoi me kohuatia mārire i runga i te wera iti, mā tēnei tukanga ka taea te whakamātotoru noa i te paura i roto i ngā pāmahana teitei mō te wā roa. Ahakoa he roa te huringa, ka taea te pupuri i te "reka taketake" o te rauemi, ā, he pai ake mō ngā wāhanga taputapu haurua-ira me ngā whakaritenga parakore tino kaha.
2. Te whakapūtanga wera-pēhi: He "tikanga hanga pēhanga-teitei" e whakahaeretia ana me te tino tika
Ko te pēhanga ā-ringa i roto i te taiao pāmahana teitei he rite ki te "mirimiri wera" tika ki te rauemi, ka taea ai te whakakore wawe i ngā āputa o roto. Ko ngā wāhanga uku i hangaia e tēnei tukanga he tata ki te uara ariā, ā, he kōwhiringa pai mō te hanga peera me ngā hiri tika.
3. Te Whakapūtanga Tauhohenga: Te "Matauranga Matū" i te Ao Rauemi
Mā te whakamahi matatau i te tauhohenga matū i waenga i te silicon me te waro, ka whakakīia aunoa ngā āputa i te wā e whakatōngia ana. Nā tēnei āhuatanga "whakaora-ake" ka waiho hei taputapu kaha mō te hanga i ngā wāhanga uaua me ngā wāhanga koretake, e tika ana mō ngā hua rerekē e ātete ana ki te pāmahana teitei, e ātete ana ki te kakahu, e ātete ana ki te waikura, me ētahi atu wāhanga kua whakaritea.
II. Te Kōwhiringa Tukanga: Te Mātauranga o te Whakarite kia Taurite
Pērā i ngā kaimahi tuitui matua e whiriwhiri ana i ngā tuitui i runga i ngā āhuatanga o te papanga, me whai whakaaro whānui ngā kaihangarau ki ngā whakaritenga o te hua:
Ina mahi ana ki ngā wāhanga angiangi, āhua koretake, ka taea e te "hangarau werohanga" o te mahi whakapūtanga tauhohenga te pupuri i te āhua tino pai.
Ka taea e ngā paepae hiko-haurua me ngā whakaritenga tino pakari mō ngā mata tino papatahi te whakarite kia kore he rerekētanga mā te whakamahi i te sintering pēhanga noa.
I te wā e mahi ana ki ngā wāhanga kawenga-teitei, ko te kiato tino-tiketike o te sintering pehi-wera te mea e whiriwhiria ana.
Iii. Ngā Huarahi Hou Hangarau e Kīhai i te Kitea
I roto i te hītori whanaketanga o te hangarau sintering, e rua ngā mahi auaha huna e tino hira ana: ko te tāpiri iti rawa o ngā AIDS sintering he rite ki te "piri ngota", e whakaiti ana i te whakapaunga pūngao me te whakarei ake i te kaha; He rite te pūnaha whakahaere pāmahana mamati ki te "kai tunu mohio", e pupuri ana i ngā huringa pāmahana i roto i te ±5℃ me te whakarite i te ōritetanga o te mahi mō ia puranga rauemi.
Mai i te mara ahumahi ātete-kakahu me te ātete-waikura ki te umanga semiconductor matatau, kei te whakahou ake ngā uku silicon carbide i te whenua o te ahumahi hou. Ko te auahatanga tonu o te hangarau sintering he rite ki te hoatu parirau ki tēnei rauemi makutu, e āhei ai te rere ki te rangi tono whānui. Hei kaihanga ngaio e whai wāhi nui ana ki te mara o ngā uku silicon carbide mō te neke atu i te tekau tau, e mārama ana a Shandong Zhongpeng ki te kōrero i waenga i ngā rauemi me te whakahaere wera atu i tētahi atu. Ko ia whakatikatika pai o te pihi sintering he wetewete anō i te tapatoru koura "pāmahana-pēhanga-wā". Ko te kimo o ia oumu me te ahi oumu kei te tuhi tonu i te upoko whanaketanga o ngā uku ahumahi. Ma te whakawhirinaki ki te whakapono o te rangahau me te whanaketanga motuhake me ngā hangarau patent maha, e whakapau kaha ana mātou ki te whakarato i ngā kaihoko ki tētahi otinga kotahi-mutu mai i te purenga rauemi mata ki te sintering tika, me te whakarite kia mau i ia hua uku silicon carbide te mahana o ngā tau tekau o te mahi toi. Ka whakatikatikahia te ara kei mua, ā, mā te hanga tonu, ka hou. Ka tono atu mātou ki a koe kia uru mai ki a mātou ki te kite i te whakamārama a tēnei mura o te whakaaro nui i roto i ngā uku ahumahi i ngā mea kāore e taea. E whakapono tonu ana mātou kei te kaha haere tonu ngā whanaketanga katoa o te pūtaiao rauemi kia taea ai e te tangata te pakaru i ngā rohe hangarau.
