Ngā Irahiko Pūtake Nikarae tohu ana i tētahi kāwai motuhake o ngā taputapu whakarewa kua hangaia mō te hono i ngā koranu mahi-teitei me ngā konganuku rerekē. Ko te momo Ni327-3 (AWS A5.11 ENiCrMo-3) he paninga konutai hauwai-iti, ā, e mahi ana i runga i te DCEP (Direct Current Electrode Positive). Ka puta i tēnei hiko te konganuku kua whakatakotoria me te kirihou tino pai, te pakari, me te ātete ki te pakaru, me te pupuri i te kaha teitei me te ātete ki te waikura pai rawa atu i ngā pāmahana rūma me ngā pāmahana teitei. Mā tōna hanganga matū ka whakarite kia pono te mahi i roto i ngā taiao uaua ka rahua ngā hiko paerewa.
Nā ngā āhuatanga whakarewa o ēnei irahiko, he tino pai mō te whakarewa i ngā koranu nikara-kromium-molibdenum. Ko te konganuku kua whakatakotoria he tata ki te 55% nikara, 20-23% chromium, me te 8-10% molibdenum, e hanga ana i tētahi hanganga moroiti pakari e ātete ana ki ngā momo waikura tae atu ki te pakaru o te rua me te ahotea. Ko ngā āhuatanga miihini ko te kaha kume neke atu i te 760 MPa me ngā tere whakaroa neke atu i te 27%, e whakarite ana i te kaha me te ngāwari o te hononga whakarewa.
Ngā tono ahumahi mōNgā Irahiko Pūtake Nikarae kapi ana i ngā rāngai maha tae atu ki te tukatuka matū, te whakaputa hiko, me te hangarau moana. He whānuitia te whakamahinga o ēnei i roto i te whakarewa i ngā wāhanga nui pērā i ngā tauhohenga, ngā whakawhiti wera, me ngā pūnaha paipa e mahi ana i raro i ngā pāmahana teitei me ngā āhuatanga waikura. E whakaatu ana ngā irahiko i te tino whai huatanga ki te hono i ngā konganuku rerekē me te whakarewa whakakikorua i runga i ngā mata maitai waro, e whakarato ana i ngā painga ōhanga me te hangarau i roto i te hanga me te whakatika taputapu.
He mea nui te whakahaere tika me ngā tikanga whakarewa mō te mahi tino pai o ēnei irahiko. Te whakamaroke i mua i te 300°C mō te 60 meneti hei whakakore i te makuku me te ārai i ngā take e pā ana ki te hauwai. Me pupuri e ngā kaiwhakahaere he roa poto o te pewa me te whakauru wera taurite hei pupuri i ngā āhuatanga whakarewa o te konganuku kua whakatakotoria. Me whakahaere ngā pāmahana i waenga i te ara i raro i te 150°C, ā, me horoi pai i waenga i ngā whakawhiti kia kore ai he koha o ngā whakarewanga, ā, kia tino ātete hoki ki te waikura.
Ngā Irahiko Pūtake Nikarawhakarato i ngā otinga nui mō ngā tono whakarewa uaua puta noa i ngā ahumahi rerekē. Ko te momo Ni327-3, e tutuki ana i ngā whakaritenga AWS ENiCrMo-3, e tuku ana i te mahi pono mā te whakakotahitanga taurite o ngā āhuatanga miihini me te ātete ki te waikura. Kei te mahi tonu ēnei irahiko hei wāhanga nui i roto i te tiaki me te hanga taputapu ahumahi e mahi ana i raro i ngā āhuatanga taiao tino kino.
