Nikara konukōrumiumaKo te nuinga o te waea he nikara (Ni) me te konukōmiuma (Cr), ā, tera pea he iti noa iho ngā huānga kei roto. Ko te nui o te nikara i roto i te koranu nikara-konukōmiuma he 60%-85% te nuinga, ā, ko te nui o te konukōmiuma he 10%-25%. Hei tauira, ko te koranu nikara-konukōmiuma noa Cr20Ni80 he 20% te nui o te konukōmiuma, ā, he 80% te nui o te nikara.

Ko te wāhanga matua o te waea parahi ko te parahi (Cu), ko tōna parakore ka eke ki te neke atu i te 99.9%, pērā i te parahi parakore T1, ko te ihirangi parahi he teitei ki te 99.95%.

2. Ngā Āhuatanga Ā-tinana Rerekē

Tae

- He hina hiriwa te waea nichrome i te nuinga o te wā. Nā te mea kua konatunatua te kanapa whakarewa o te nickel me te chromium hei homai i tēnei tae.

- He whero papura te tae o te waea parahi, koinei te tae noa o te parahi, ā, he kanapa whakarewa tōna.

Kiato

- He nui te mātotoru raina o te koranu nikara-konukōmiuma, tata ki te 8.4g/cm³. Hei tauira, ko te taumaha o te 1 mita pūtoru o te waea nikara he tata ki te 8400 kg.

- Tewaea parahiKo te mātotorutanga he tata ki te 8.96g/cm³, ā, he taumaha ake te rōrahi ōrite o te waea parahi i te waea koranu nikara-konukōmiuma.

Te Pūwāhi Rewa

-He teitei te ira rewa o te koranu nikara-konukōmiuma, tata ki te 1400°C, ā, ka taea te mahi i ngā pāmahana teitei ake, me te kore e ngāwari te rewa.

-Ko te ira rewa o te parahi he tata ki te 1083.4℃, he iti iho i te ira rewa o te nikara-konukōmiuma.

Te Arahi Hiko

-He tino pai te kawe hiko o te waea parahi, i roto i te āhua paerewa, ko te kawe hiko o te parahi he tata ki te 5.96×10 S/m. Nā te hanganga hiko o ngā ngota parahi ka taea e ia te kawe pai i te iahiko, ā, he rauemi kawe hiko e whakamahia whānuitia ana, e whakamahia whānuitia ana i roto i ngā mara pēnei i te tuku hiko.

He iti te kawe hiko o te waea koranu nikara-konukōmiuma, ā, he iti iho tōna kawe hiko i tērā o te parahi, tata ki te 1.1×10⁶S/m. Nā te hanganga ngota me te taunekeneke o te nikara me te konukōmiuma i roto i te koranu tēnei, ā, ka āraia te kawe hiko o ngā irahiko ki tētahi taumata.

Te kawe wera

-He tino pai te kawe wera o te parahi, ā, ko tōna kawe wera he tata ki te 401W/(m·K), ā, nā tēnei ka whakamahia whānuitia te parahi ki ngā wāhi e hiahiatia ana te kawe wera pai, pērā i ngā taputapu whakamarara wera.

He ngoikore te kawe wera o te koranu nikara-konukōmiuma, ā, ko te kawe wera kei waenganui i te 11.3 me te 17.4W/(m·K)

3. Ngā Āhuatanga Matū Rerekē

Ātete ki te Waikura

He pai te ātete o ngā koranu nikara-konukōmiuma ki te waikura, inā koa i roto i ngā taiao waikura pāmahana teitei. Ka hangaia e te nikara me te konukōmiuma he kiriata waikura matotoru ki runga i te mata o te koranu, ka ārai i ngā tauhohenga waikura anō. Hei tauira, i roto i te hau pāmahana teitei, ka taea e tēnei paparanga kiriata waikura te tiaki i te konganuku i roto i te koranu mai i te waikura anō.

- He ngāwari te waikura o te parahi i te hau hei hanga i te vercas (te konupūmā parahi taketake, te tātai Cu₂(OH)₂CO₃). Ina koa i roto i te taiao makuku, ka waikura haere te mata o te parahi, engari he pai te ātete ki te waikura i roto i ētahi waikawa kore-waikura.

Te Pūmautanga Matū

- He tino pumau te matū o te koranu nichrome, ā, ka taea te noho pumau ahakoa he maha ngā matū. He ātete ki ngā waikawa, ngā kawa me ētahi atu matū, engari ka taea hoki te tauhohe ki ngā waikawa waikura kaha.

- I raro i te mahi a tētahi tauhohenga matū kaha ake te parahi i roto i ētahi waikura kaha (pērā i te waikawa hauota), ko te whārite tauhohenga ko \(3Cu + 8HNO₃(wairewa)=3Cu(NO₃ +2NO↑ + 4H₂O\).

4. Ngā Whakamahinga Rerekē

- waea koranu nikara-konupora

- Nā tōna ātete teitei me tōna ātete pāmahana teitei, e whakamahia ana mō te hanga i ngā wāhanga whakamahana hiko, pērā i ngā waea whakamahana i roto i ngā oumu hiko me ngā whakamahana wai hiko. I roto i ēnei taputapu, ka taea e ngā waea nichrome te huri i te pūngao hiko hei wera.

- Ka whakamahia hoki i ētahi wā ina hiahiatia kia mau tonu ngā āhuatanga ā-pūkaha i roto i ngā taiao pāmahana teitei, pērā i ngā wāhanga tautoko o ngā oumu pāmahana teitei.

- Waea parahi

- Ko te waea parahi te mea e whakamahia nuitia ana mō te tuku hiko, nā te mea he pai te kawe hiko ka taea te whakaiti i te ngaronga o te pūngao hiko i te wā e tuku ana. I roto i te pūnaha whatunga hiko, he maha ngā waea parahi e whakamahia ana hei hanga waea me ngā taura.

- Ka whakamahia hoki hei hanga hononga mō ngā wāhanga hiko. I roto i ngā hua hiko pēnei i ngā rorohiko me ngā waea pūkoro, ka taea e ngā waea parahi te tuku tohu me te tuku hiko i waenga i ngā wāhanga hiko.
