Ko te Whakarewa Werohanga Whakarewa (MIM) he momo hangarau whakarewa paura hou, i whakawhanakehia mai i te whakarewa werohanga paura (PIM) o ngā wāhanga uku. Ko ngā mahi whakaputa matua o te Whakarewa Werohanga Whakarewa penei: te whakaranu i te paura whakarewa me te here-whakapūtanga-whakarewa werohanga-whakakore hinu-whakakī-maimoatanga whai muri-hua whakamutunga, he pai te hangarau mō ngā wāhanga whakarewa paura whakaputa papatipu iti, uaua, mahi teitei, pērā i ngā mea e whakamahia ana e te umanga mataaratanga Huiterangi hei hanga wāhanga mataaratanga. I ngā tekau tau tata nei, kua tere te whanaketanga o te hangarau MIM, ko ngā rauemi e tika ana ko: te koranu Fe-Ni, te kowiri tira, te koranu taputapu, te koranu taumaha motuhake teitei, te carbide sima, te koranu titanium, te koranu super-based ni, te matū intermetallic, te alumina, te zirconia me ētahi atu. Ko te hangarau Whakarewa Werohanga Whakarewa (MIM) e hiahia ana kia iti iho i te micron te rahi o te matūriki o te paura, ā, kia tata porowhita te āhua. Hei tāpiri, me whai kiato wetewete, kiato wiri, te ōwehenga o te roa ki te diameter, te koki pari tūturu me te tohatoha rahi matūriki. I tēnei wā, ko ngā tikanga matua mō te whakaputa paura mō te hangarau whakarewa werohanga whakarewa ko te whakakorikori wai, te whakakorikori hau me te tikanga rōpū waroira. Ko ngā momo paura e whakamahia whānuitia ana mō te werohanga o ngā konganuku kowiri tira ko: 304L, 316L, 317L, 410L, 430L, 434L, 440A, 440C, 17-4PH, me ētahi atu. Ko te tukanga whakakorikori wai e whai ake nei: te whiriwhiri i ngā rauemi mata kowiri tira - te whakarewa i roto i te oumu whakakorikori auau-waenga - te whakatikatika hanganga - te tango i te waikura me te paru - te whakakorikori me te kuru - te kimi kounga - te tirotiro - te takai me te rokiroki, ko ngā taputapu matua e whakamahia ana ko: te oumu whakakorikori auau-waenga, te papu wai pēhanga-teitei, te taputapu kuru kati, te tāke wai hurihuri, ngā taputapu tirotiro me te takai, me ngā taputapu whakamātautau.
Te tukanga ote whakaātomo haupenei:
te whiriwhiri i ngā rauemi mata o te kowiri tira - te whakarewa i roto i te oumu whakapūmau auau-waenga - te whakatikatika hanganga - te tango i te waikura me te para - te whakakorikori me te kuru - te kimi kounga - te tirotiro - te takai me te rokiroki. Ko ngā taputapu matua e whakamahia ana ko: te oumu rewa whakakorikori auau-waenga, te pūtake hauota me te taputapu whakakorikori, te tāke wai hurihuri, ngā taputapu tirotiro me te takai, me ngā taputapu whakamātautau. He painga me ngā ngoikoretanga o ia tikanga: Ko te Whakakorikori Wai te tukanga kuru matua, he tino pai te mahi, he iti ake te ohanga o te whakaputanga nui, ka taea te hanga i te paura kia maeneene, engari he koretake te āhua, he pai ki te tiaki i te āhua, engari he nui ake te pānga o te here e whakamahia ana ki te tika. Hei tāpiri, ko te kiriata whakakorikori i hangaia e te tauhohenga o te wai me te konganuku i te pāmahana teitei ka aukati i te sintering. Ko te Whakakorikori Hau te tikanga matua ki te whakaputa paura mō te hangarau whakakorikori werohanga konganuku. He porowhita te paura i hangaia e te whakakorikori hau, he iti te tohu waikura, he iti ake te here e hiahiatia ana, ā, he pai te hanga, engari he iti te hua o te paura tino-pai, he nui te utu, ā, he iti te āhuatanga pupuri āhua, he pānga te c, N, H, O i roto i te here ki te tinana sintered. He tino parakore te paura i hangaia mā te tikanga carbonyl, he pumau i te tīmatanga, ā, he tino angiangi te rahi o te matūriki. He tino pai mō te MIM, engari mō te Fe, Ni me ētahi atu paura anake, kāore e taea te whakatutuki i ngā whakaritenga o ngā momo. Hei whakatutuki i ngā whakaritenga o te paura mō te hanga whakarewa, he maha ngā kamupene kua whakapai ake i ngā tikanga o runga ake nei, ā, kua whakawhanake i ngā tikanga moroiti-atomization me te laminar atomization. Ināianei ko te paura wai-atomized me te paura hau-atomized te whakamahinga whakauru, ko te tuatahi hei whakapai ake i te kiato o te whakakīkī, ko te tuarua hei pupuri i te āhua. I tēnei wā, mā te whakamahi i te paura wai-atomizing ka taea hoki te whakaputa i te tinana sintered me te kiato whanaunga neke atu i te 99%, nō reira ko te paura wai-atomizing anake ka whakamahia mō ngā wāhanga nui ake, ā, ko te paura hau-atomizing ka whakamahia mō ngā wāhanga iti ake. I ngā tau e rua kua pahure ake nei, kua whakawhanakehia e Handan Rand Atomizing Pulverizing Equipment Co., Ltd. tētahi momo taputapu hou mō te paura atomizing, e kore e taea anake te whakarite i te whakaputanga nui o te paura wai-atomizing me te paura tino angiangi, engari me whakaaro hoki ki ngā painga o te āhua paura porowhita.
