Ko ngā konukōre e ahu mai ana i te nikara he konganuku hangahanga kei roto ko te nikara hei huānga matua, he maha ngā wā ka neke atu i te 50% te taumaha. Mā tō rātou hanganga iti ka taea te kaha miihini tino pai, te ātete ngoki, me te pumau waikura tae atu ki te 800°C. Nā ēnei āhuatanga ka nui te whakamahinga o ngā konukōre e ahu mai ana i te nikara i roto i ngā miihini rererangi, ngā tāwhana hau, ngā tipu hiko karihi, me ngā tauhohenga matū kei reira te wera nui me ngā taiao waikura. I roto i te rererangi, ka whakaratohia e ngā konukōre tino pai pērā i a Inconel me Nimonic te ātete ngenge i te huringa pāmahana tere. Mō te tukatuka matū, ka mau tonu te mahi a ngā konukōre i roto i ngā pāpāho waikawa nui, i ngā pāpāho chlorine rānei.
Ngā Ngongo Koranu Nikara

Te Tūranga o ngā Huānga Whakakotahi: Te Rino, te Nikara, te Konukōmiuma, me tua atu
Ka pā tika ngā tāpiritanga huānga ki te mahi a te rauemi me te ātete ki te waikura. Ko te nui o te chromium mai i te 19% ki te 23% ka taea te hanga i tētahi paparanga waikura tiaki tonu, ka whakanui ake i te ātete ki ngā matū waikura me te whakapai ake i te roa o te ora i roto i te maitai kore waikura me ngā superalloys. Ka whakaū te nikara i te hanganga tioata me te whakanui ake i te ātete wera, inā koa i roto i ngā pūnaha koranu rino-nikara-chromium. Ko te tāpiritanga o te molibdenum, i ngā taumata tae atu ki te 9%, ka whakanui ake i te ātete ki te waikura poka me te kapiti e kitea ana i roto i te wai moana me ngā taiao matū kaha. Ka whai wāhi te rino ki te pumau ā-pūkaha mā te whakapakari i te otinga, ā, ka whakarato i te whai huatanga utu i roto i ngā momo taumata maha.
Te Hiranga o te Whakatau Tika i te Hanganga Huānga
Te Mahi, te Whakatutukitanga, me te Roa o te Ora
Mā ngā raraunga hanganga huānga tika ka tutuki ngā paerewa miihini me te haumaru o ngā koranu nikara i roto i te rererangi me te whakaputa hiko. Ko ngā ōwehenga rino, nikara, me te chromium e tino whakahaeretia ana (hei tauira, 60–75% Ni, 19–23% Cr) ka pā tika ki te kaha kume me te ātete ngoki i te 700–1100°C. Ka taea e te tātaritanga hē te pakaru ohorere, te ngaronga o te pono o te pāmahana teitei, te pakaru kino rānei i roto i ngā pāpāho kaha. Ko te whakapumautanga kounga me te whai i ngā mea ka whakawhirinaki ki te manatoko huānga tika mō te tutuki i ngā ture me te whakamana pūtāhui.
Te Ihirangi Chromium me te Ātete ki te Waikura
Ko te chromium i te 19–23% ka hanga i tētahi kiriata waikura Cr₂O₃ tonu, he mea nui mō te ātete ki ngā waikawa, ki ngā matū whakakā, me te waikura pāmahana teitei. Ko te ātete ki te waikura o te maitai kore waikura me whai ōrau chromium iti rawa: i raro i te 19% ka nui ake te pakaru me te whakaekenga intergranular. I roto i ngā koranu nikara-chromium-rino e whakamahia ana i roto i ngā tipu matū, ko te ngaronga o te 2% chromium ka whakaiti i te roa o te mahi mā te 40%, ka nui ake te tiaki me te kore e whakaritea ngā wā mutu hiko.
Ngā Wero Matua i roto i te Tātari Huānga mō ngā Koranu e Hangai ana ki te Nikara
He taupatupatu ngā tihi fluorescence o te rino, te nikara, me te chromium, ā, ka uaua ake te ine i te XRF, i te ine i te ine ira rānei. Ko ngā matrices maha-huānga me te molybdenum iti, te niobium rānei, me whai whakatikatika pumau me te tika. Ko ngā hapa mai i ngā pānga matrix, i te nekeneke whakatikatika rānei ka hua ake he whakarōpūtanga koranu hē, he mōrearea ki te pono, he takahi rānei i ngā kirimana hangarau, me ngā kereme whakamana me te whakaraeraetanga nama.
Me pēhea te whakatinana i te tātaritanga XRF i roto i tō whare
Te Whakarite Tauira me ngā Tikanga Pai rawa atu
He mea nui kia ma ngā mata tauira; tangohia te hinu, ngā waikura, ngā matūriki rānei. Mā ngā āhua papatahi, ōrite ka pai ake te tika, engari ka urutau a Lonnmeter XRF ki ngā āhua koretake.
Te Whakauru i te XRF ki roto i ngā Rerenga Mahi Whakapūmau Kounga
Whakamahia te XRF mō te manatoko puranga o ia rā, te tirotiro taumai, me te QC e haere atu ana. Aroturukihia ngā putanga tātari hei whakarite i te ōritetanga o te hua mai i te tīmatanga ki te mutunga.
Te Whakahaere Raraunga me te Aroturuki
Penapenahia ngā rekoata inenga mā te mamati hei arotake ture me te whai i ngā tukanga. Kaweakehia ngā hua ki ngā pātengi raraunga whare mō te whakahaere kounga pokapū.
Mā te tātaritanga Lonnmeter XRF ka taea te tātari tere i ngā huānga o ngā tauira koranu totoka. Ka tukuna ngā hua mō te rino, te nikara, te chromium, me te molybdenum i roto i ngā hēkona, me te aro ki te chromium ki te 0.01%. Ka taea te kaweake i ngā raraunga tātari mō te whai i ngā whakaritenga me te tutuki i ngā whakaritenga arotake.
Ngā Pātai Auau
He aha ngā koranu e hangai ana ki te nikara, ā, he aha i hiranga ai?
Ko ngā koranu nikara he mea whakarewa, ko te nikara te huānga matua, ā, i te nuinga o te wā ka koranuhia ki te rino me te chromium. E whakaatu ana ēnei koranu i te kaha tino pai ki te pāmahana teitei, te ātete ki te waikura, me te pumau i roto i ngā taiao mahi kaha.
He aha te mea nui ai te nui o te chromium i roto i ngā koranu e hangai ana ki te nikara?
Ka hanga noa te chromium i tētahi paparanga whakakorenga Cr₂O₃ i runga i ngā mata koranu kei runga ake i te 12% te ihirangi. Ko ngā koranu he 19–23% te chromium ka whakaatu i te tiakitanga tino nui, ka aukati i te horapa o te hāora me ngā halide ki roto.
