Taitara: Te Hiranga o ngā Oumu Whakaoho Korehau i roto i te Whakarewa Koranu

I te whakarewa i ngā konukōre, me tino tika, me whakahaere hoki te tukanga kia tutuki ai ngā āhuatanga e hiahiatia ana. Ko tētahi āhuatanga matua o tēnei tukanga ko te whakamahinga o te oumu whakapūngao korehau. He mahi nui tā ēnei oumu ki te whakarewa i ngā momo konukōre, he rerekē ngā whakaritenga o ia oumu. I roto i tēnei tuhinga, ka tūhuratia e mātou ngā momo konukōre rerekē e tika ana kia whakarewahia i roto i te...oumu whakapūmau korehaume ngā take mō tō rātou hiahiatanga.

Ko tētahi o ngā konukōre e whakamahia whānuitia ana hei whakarewa mā te whakamahi i te oumu whakapūngao korehau ko te kowiri tira. He konukōre maha ngā whakamahinga o te kowiri tira, mai i ngā taputapu kīhini ki ngā mīhini ahumahi. Ko te tukanga whakarewa o te kowiri tira me whakahaere tika te hanganga o te konukōre me te tango i ngā poke pērā i te waro me te whanariki. Ka whakaratohia e ngā oumu whakapūngao korehau he taiao pai mō te whakarewa i te kowiri tira nā te mea ka taea e rātou te whakahaere tika i te pāmahana me te āhuarangi i te wā e whakarewa ana.

Ko tētahi atu koranu nui i whakarewaina mā te whakamahi i te oumu whakapūngao korehau ko te koranu konukōre-rhodium. E mōhiotia ana te koranu konukōre-rhodium mō tōna ōwehenga kaha-ki-taumaha me te ātete ki te waikura, ā, he rauemi nui tēnei mō ngā ahumahi pēnei i te rererangi me ngā taputapu hauora. Me nui te parakore o te whakarewa i te koranu konukōre-rhodium nā te mea ahakoa he iti noa ngā poke ka pā kino ki ōna āhuatanga. Ka taea e ngā oumu whakapūngao korehau te hanga i te taiao parakore teitei e hiahiatia ana hei whakarewa i te koranu konukōre-rhodium, ā, he mea nui ēnei mō te whakaputa i tēnei koranu utu nui.

I roto i te umanga rererangi, he nui te hiahia mō ngā superalloys nā te mea ka taea e rātou te tu atu i ngā pāmahana tino nui me ngā ahotea miihini. Ka whakamahia ēnei koranu i roto i te hanga o ngā mata tāpine, ngā wāhanga miihini me ētahi atu wāhanga nui mō ngā waka rererangi me ngā waka mokowhiti. Ko te whakarewa i ngā koranu pāmahana-tiketike pērā i a Inconel me Hastelloy me whakahaere tika i ngā tukanga rewa me te whakapakeketanga me te tango i ngā poke. Ka whakaratohia e ngā oumu whakapūngao korehau ngā tikanga e tika ana mō te whakarewa i ngā koranu pāmahana-tiketike hei whakaputa rauemi kounga-tiketike, mahi-tiketike mō ngā tono rererangi.

I roto i te umanga motuka, he whānuitia te whakamahinga o ngā koranu konumohe nā te mea he mama, he ātete hoki ki te waikura. Me āta whakahaere te whakarewa me te whakarewa i ngā koranu konumohe kia tutuki ai ngā āhuatanga miihini e hiahiatia ana. Ka whakaratohia e ngā oumu whakapūngao korehau te whakahaere pāmahana tika me te āhuarangi e hiahiatia ana hei whakarewa i ngā koranu konumohe, he mea nui tēnei mō te whakaputa rauemi motuka kounga teitei.

I roto i te umanga hauora, ka whakamahia ngā koranu hototahi-koiora pērā i ngā koranu titanium me ngā koranu cobalt-chromium i roto i te hanga o ngā mea whakauru me ngā taputapu hauora. Ko te whakarewa i ēnei koranu me whai taumata teitei o te parakore me te whakahaere i te hanganga kia tutuki ai ngā whakaritenga pakari mō te hototahi-koiora me ngā āhuatanga miihini. Ka whakaratohia e ngā oumu whakapūngao korehau ngā tikanga e tika ana mō te whakarewa i ngā koranu hototahi-koiora, ā, he mea nui mō te hanga rauemi hauora.

I roto i te umanga hikohiko, ka whakamahia ngā koranu parahi mō ō rātou kawe hiko me ngā āhuatanga wera. Me whakahaere tika te hanganga me te tango i ngā paru i te whakarewanga o ngā koranu parahi kia tutuki ai ngā āhuatanga hiko me ngā āhuatanga miihini e hiahiatia ana. Ka whakaratohia e ngā oumu whakapūngao korehau he taiao pai mō te whakarewa i ngā koranu parahi hei whakaputa rauemi kounga teitei mō ngā tono hiko.

Hei whakarāpopototanga, he mea nui te mahi a ngā oumu whakapūngao korehau i roto i te whakarewanga o ngā momo koranu, he rerekē ngā whakaritenga o ia oumu. Mai i te kowiri tira ki te titanium, mai i ngā koranu pāmahana-tiketike ki ngā koranu konumohe, mai i ngā koranu hototahi-koiora ki ngā koranu parahi, ka whakaratohia e ēnei oumu ngā tikanga e tika ana mō te whakaputa rauemi kounga teitei mō ngā momo ahumahi. Ko te whakahaere pāmahana tika, te āhuarangi me te parakore e tutukihia ana mā te whakarewa whakapūngao korehau he mea nui ki te whakatutuki i ngā whakaritenga pakari o ngā koranu hou. I te haere tonu o te whanaketanga o te hangarau, ka nui ake te hiranga o te mahi a ngā oumu whakapūngao korehau i roto i te whakarewa koranu ki te whakatutuki i ngā hiahia o ngā momo ahumahi.
