Ni200meNi201e rua ngā momo koranu nikara parakore e whakamahia whānuitia ana, e rongonui ana mō tō rātou ātete ki te waikura, te kawe hiko, me te ngāwari o te miihini. Hei hua matua i roto i te whānau koranu nikara (he ≥99.6% te nui o te nikara e rua), ko tō rātou rerekētanga ngawari engari he mea nui i roto i te hanganga matū e hanga tika ana i ō rātou rohe mahi me te whānuitanga o te tono—e kapi ana i ngā waea, ngā pepa, ngā ngongo, me ngā wāhanga ritenga. Kei raro nei he whakataurite taipitopito hei āwhina i a koe ki te whiriwhiri i te koranu tino pai mō tō kaupapa:

Te āheinga ki te mīhini	He pai ake i te pāmahana rūma (ka pai ake te mahi tapahi mā te waro nui ake)	He iti ake te āhua (ka whakapiki ake te waro iti i te piri o te taputapu; ka arotauhia mō te hanga i te pāmahana teitei)
Utu	He iti ake te utu (he whānui ake ngā rauemi mata; he māmā ake te tukanga whakaputa)	He paku teitei ake (he utu tāpiri atu mā ngā tukanga whakahaere me te purenga waro tino pakari)
Ngā Horopaki Taupānga Noa (Ngā Āhua Koranu)	Waea: Ngā ripa pākahiko, ngā hononga hiko; Ngā pepa/ngongo: Ngā tāke matū pāmahana-iti, ngā wāhanga taputapu cryogenic	Waea: Ngā wāhanga whakamahana pāmahana-tiketike, ngā irahiko whakarewa; Ngā Rau/Ngongo: Ngā paipa tukanga matū, ngā wāhanga hanganga rererangi, ngā anga pūoko pāmahana-tiketike

1. Rerekētanga Matua: Te Ihirangi Waro (Te "Waewehenga Mahi")

Ko te rerekētanga matua i waenga i te Ni200 me te Ni201 kei roto i te whakahaere i te ihirangi waro—ko tēnei āhuatanga kotahi te mea e whakatau ana i te pono o tō rātou mahi ki te pāmahana teitei me te ngāwari ki te urutau ki te tukatuka:

lNi200 KoranuMe te nui o te waro o te 0.10%, ka taurite te kaha ki te miihini i te pāmahana rūma me te mahi taketake. Heoi, i ngā pāmahana neke atu i te 600°C, ka honoa ngā ngota waro i roto i te koranu ki te nikara hei hanga i ngā kāpia nikara (Ni₃C), ka puta ake i ngā rohe o te kōra. Ka hua ake tēnei i te pakarukaru o te kōrau: ka pakarukaru te koranu, ka ngaro te ngāwari, ā, ka ngawari ki te pakaru i raro i te ahotea miihini, i te huringa wera rānei—ka whakawhāiti i tōna whakamahinga i roto i ngā taiao pāmahana teitei.

lNi201 KoranuMā te whakawhāiti rawa i te waro ki te ≤0.02%, ka whakakorea te maturuturunga waro ahakoa i te 750°C. Mā te iti rawa o te waro ka tiakina te pumau o te hanganga o te koranu, ka whakarite kia pumau te ngāwari me te kaha miihini i te wā roa o te mahi pāmahana teitei. Nā tēnei ka waiho hei whiringa matua mō ngā tono e hiahia ana kia roa te wera.

2. Ātete Pāmahana me te Whakarerekētanga Āhua Koranu

He tino pai te ātete o ngā koranu e rua ki te waikura, engari he rerekē rawa ngā rohe pāmahana me te pai mō ngā momo koranu rerekē:

lNi200 Koranu: Kua arotauhia mō ngā āhuatanga pāmahana iti-ki-waenga (≤650°C), ka tiaho i roto i ngā tono e whakatairangahia ana te kawe hiko me te ngāwari tukatuka pāmahana-rūma. Hei waea, he mea tino pai mō ngā ripa pākahiko (litium-ion, pākahiko waikawa-mata) me ngā hononga hiko-iti—nā tōna kawe teitei (0.069 Ω·mm²/m) ka whakaiti i te ngaronga pūngao, ā, nā tōna ngāwari tino pai (≥40%) ka taea te kume ki roto i ngā waea tino-pai (ki raro ki te 0.005mm) me ngā piko uaua. Hei pepa, hei ngongo rānei, ka whakamahia i roto i ngā tāke rokiroki matū pāmahana-iti me ngā taputapu cryogenic, he mea nui te ātete ki te waikura me te ngāwari ki te hanga matao.

lNi201 KoranuI hangaia mō te mahi pāmahana teitei (600°C–750°C), he tino pai ki ngā taiao uaua. Hei waea, ka whakakaha i ngā wāhanga whakamahana oumu ahumahi me ngā irahiko whakarewa—nā tōna pumau pāmahana teitei ka roa te ora mahi (8,000+ hāora i roto i te whakamahana tonu). Hei pepa, hei ngongo rānei, ka whakamahia ki roto i ngā paipa tukanga matū (e whakahaere ana i ngā waikawa pāmahana teitei) me ngā wāhanga hanganga rererangi, he mea nui te ātete ki te ngenge wera me te hau waikura. Nā tōna āheinga whakarewa ka whakakorea te hiahia mō te whakamahana i muri i te whakarewa, ka whakangawari ake i te hanga o ngā wāhanga nui.

3. Ngā Āhuatanga Tukatuka me te Whai Hua o te Whakaputa

lNi200 KoranuMā te nui ake o te waro ka taea te whakamahi i te mīhini i roto i te pāmahana rūma—he maeneene ake ngā tukanga tapahi, keri, me te tā, ka whakaiti i te pakaru o ngā taputapu me te wā whakaputa. Nā tēnei ka iti ake te utu mō ngā wāhanga i hangaia nuitia pērā i ngā ripa pākahiko me ngā whare pūoko pāmahana-iti. Heoi, me whakamahana te whakarewa Ni200 i muri i te whakarewa hei whakamama i te ahotea o roto me te tango i te hanganga carbide pea i roto i ngā hononga whakarewa, ka tāpirihia he taahiraa whakaputa mō ngā tono pāmahana-tiketike.

lNi201 KoranuAhakoa he iti te waro e whakaiti ana i te kaha o te miihini i te pāmahana rūma (tērā pea ka piri te taputapu), he tino pai ki ngā tukanga hanga pāmahana teitei (hei tauira, te hurihuri wera, te hanga). He mea nui te kaha o tōna whakarewa: ka mau tonu te kaha me te ngāwari o ngā hononga whakarewa me te kore e whakamahana, ka tapahia ngā huringa whakaputa mō ngā wāhanga nui pēnei i ngā paipa matū, ngā wāhanga rererangi rānei. Mō ngā tono e pā ana ki te whakarewa, te hanga pāmahana teitei rānei, ka nui ake te pai me te pono o te whakaputanga a Ni201.

4. Aratohu Kōwhiringa me te Whai Hua o te Utu

Kōwhiria te Ni200 Alloy mēnāMe whai otinga utu iti koe mō ngā tono pāmahana iti ki te reo (≤600°C), ahakoa te āhua (waea, rau, ngongo). He mea tino pai mō:

Ngā hikohiko kaihoko (ngā ripa pākahiko, ngā hononga)

Ngā taputapu matū pāmahana-iti (ngā tāke rokiroki, ngā paipa pēhanga-iti)

Ngā wāhanga cryogenic (ngā pūnaha whakahaere hau wai)

Ngā wāhanga hanga papatipu e hiahia ana ki te miihini i te pāmahana rūma

Kōwhiria te Ni201 Alloy mēnāKei roto i tō kaupapa ngā pāmahana teitei (600°C–750°C), te whakarewa, ngā taiao waikura rānei—ahakoa he iti noa te utu, ka puta he hua mō te wā roa. He tino pai mō:

Whakamahana ahumahi (ngā koiri pāmahana-tiketike, ngā huānga oumu)

l Te tukatuka matū (ngā paipa waikawa pāmahana-teitei, ngā arai tauhohenga)

l Te rererangi me te parepare (ngā wāhanga hanganga pāmahana-tiketike, ngā anga pūoko)

Ngā huihuinga whakarewa (kāore e hiahiatia he maimoatanga wera i muri i te whakarewa)

Whakarāpopototanga

He koranu nikara parakore kounga teitei te Ni200 me te Ni201, engari he rerekē te nui o te waro e puta ai he kaha motuhake. Ko te Ni200 te whiringa ohanga, maha ngā whakamahinga mō ngā tono pāmahana iti, mīhini, kawe hiko rānei puta noa i ngā momo waea, pepa, me ngā ngongo. Ko te Ni201 te whiringa tino pai mō ngā āhuatanga pāmahana teitei, ātete ki te whakarewa, ātete ki te waikura rānei, ina tika te pono me te pakari hei utu mō te pikinga iti o te utu.
