Ngā Hangarau Hou i roto i te Whakarewa Paura
1. Te Hanganga Tāpiri (AM)
Kua hurihia e te Additive Manufacturing, e mōhiotia whānuitia ana ko te tānga 3D, te mahi whakarewa paura. Ka whakamahia e tēnei hangarau ngā paura whakarewa papatahi i te papatahi hei hanga i ngā wāhanga. E rua ngā tikanga AM rongonui ko te Selective Laser Melting (SLM) me te Electron Beam Melting (EBM).
– Te Rewa Taiaho Whiriwhiri (SLM): Ka whakamahia he taiaho e ārahitia ana e te rorohiko hei whakarewa i te paura whakarewa papatahi i te papatahi, kia puta ai ngā wāhanga he tino tika, he tino uaua hoki te āhuahanga.
– Te Rewa o te Hiko Irahiko (EBM): Ka whakamahia he hihi irahiko hei whakarewa i te paura whakarewa i roto i te korehau, kia nui ake ai te mana whakahaere i te kiato me te kounga o te rauemi whakamutunga.
Ko ngā painga o te AM ko te kaha ki te waihanga i ngā tauira tere, te whakaiti i te wā whakawhanake hua, me te kaha ki te waihanga i ngā hanganga ā-roto uaua pēnei i ngā whatunga mama e whakamahia ana i roto i ngā wāhanga rererangi.
2. Te Pēhi Wera Isostatic (HIP)
Ko te Pēhi Wera Isostatic he hangarau e whakamahi ana i te pēhanga teitei me te pāmahana i roto i te taiao isostatic hei whakakīkī i ngā paura whakarewa. Ka taea e te Pēhi Wera Isostatic te whakakore i te porosity o roto o ngā rauemi, ka whakanui ake i tōna kaha me tōna roa.
Ko ngā tono HIP e kitea nuitia ana i roto i ngā ahumahi rererangi me te hauora, he mea nui te pono me te pakari o ngā rauemi. Hei tauira, he nui ake te pono o ngā wāhanga miihini tāpoi hau i hangaia ki te HIP nā te iti o te porosity.
3. Te Whakapūtanga Plasma Spark (SPS)
Ko te Spark Plasma Sintering he hangarau sintering e whakamahi ana i te pēhanga miihini me te iahiko hiko e pupuhi ana hei whakakotahi i ngā paura whakarewa. He maha ngā painga o te SPS, pērā i te wā sintering poto ake, te pāmahana sintering iti ake, me te whakapai ake i ngā āhuatanga miihini me te wera o te rauemi whakamutunga.
E whakamahia whānuitia ana te SPS i roto i ngā rangahau rauemi nā tōna kaha ki te pupuri i te rahi o te kōpura me ngā wāhanga pumau ka taea te whakapai ake i ngā āhuatanga ā-pūkaha me ngā āhuatanga ā-tinana o te rauemi.
4. Rererangi Whakapiri
Ko te Binder Jetting he hangarau e whakamahi ana i te wai here e rehuhia ana ki runga i te paparanga paura whakarewa hei hanga i tētahi wāhanga. Kātahi ka taea te whakamahana i te wāhanga hei tango i te here, ā, ka whakapakeketia anō mā te tukanga sintering.
Ka whakaitihia ngā utu whakaputa me te wā mā te whakamahi i te hononga whakapiri, ā, ka whakaratohia hoki he ngāwari ki te hoahoa. E whakamahia whānuitia ana tēnei hangarau i roto i te hanga tauira tere, te whakarewa anga mō ngā whakarewatanga whakarewa, me ētahi tono hauora pēnei i te hanga i ngā whakaurunga wheua whaiaro.
