Ātete Hiko Porowhita Nicr Alloy 1 – 5 Mohm mō ngā Wāhanga Whakamahana o te Hauhautanga

1. Whakaahuatanga Whānui o ngā Rauemi

Konatanāhe koranu parahi-nikora e mōhiotia ana koEureka,Whakamua, meWaka. Ko te nuinga o te wā he 55% te parahi me te 45% te nikara. Ko tōna āhuatanga matua ko tōna ātete, he pumau tonu i runga i te whānuitanga o ngā pāmahana. E mōhiotia ana ētahi atu koranu he rite te iti o ngā tauwehenga pāmahana, pērā i te manganin (Cu₈₆Mn₁₂Ni₂).

Mō te ine i ngā momo taumahatanga tino nui, 5% (50 000 microstrian) neke atu rānei, ko te constantan whakamahana (koranu P) te rauemi whatunga e whiriwhiria ana i te nuinga o te wā. He tino pai te Constantan i roto i tēnei āhuangāwari; ā, mō ngā roa ine o te 0.125 inihi (3.2 mm) me te roa ake, ka taea te whakatautau ki te >20%. Heoi anō, me maumahara, i raro i ngā taumahatanga huringa teitei, ka whakaatu te koranu P i ētahi huringa ātete pumau me ia huringa, ā, ka puta he pānga e rite ana.korete nekehanga o te ine taumahatanga. Nā tēnei āhuatanga, me te āhua o te pakaru wawe o te whatunga me te taumahatanga anō, kāore i te tūtohutia te koranu P mō ngā tono taumahatanga hurihuri. Kei te wātea te koranu P me ngā tau STC o te 08 me te 40 hei whakamahi i runga i ngā konganuku me ngā kirihou.

2. Whakataki me ngā tono o te kōanga

He puna huri porowhita, he puna makawe rānei, i roto i te karaka whakaoho.

He puna hikohiko. I raro i te pēhanga ka paheke ngā koiri tetahi ki tetahi, ā, ka roa ake te haere.

Ngā puna pūngao poutū o te tāke Stuart

Ngā puna kume i roto i tētahi taputapu haruru rārangi kua whakapikoa.

He pae hurihuri kua takahurihia i raro i te kawenga

Puna rau i runga i te taraka
Ka taea te whakarōpū i ngā puna i runga i te āhua o te kaha kawenga e pā ana ki a rātou:

Puna tāroa/whakatoro – kua hangaia te puna kia whakahaerehia me te kawenga tāroa, nō reira ka totoro te puna i te wā e pāngia ana te kawenga ki runga.
Puna kōpeketanga – he mea hanga kia whakahaerehia me te kawenga kōpeketanga, nō reira ka poto haere te puna i te wā e pāngia ana te kawenga ki runga.
Puna takahuri – he rerekē ki ngā momo o runga ake nei, ko te kawenga he kaha tuaka, ko te kawenga e pā ana ki te puna takahuri he kaha takahuri, ā, ka huri te pito o te puna mā roto i tētahi koki i te wā e pā ana te kawenga.
Puna pumau – ka noho tonu te kawenga e tautokona ana puta noa i te huringa piko.
Puna rerekē – ka rerekē te ātete o te koiri ki te kawenga i te wā e pēhia ana.
Puna pakari rerekē – ka taea te whakarerekē i te ātete o te koiri ki te kawenga, hei tauira, e te pūnaha whakahaere, ka rerekē anō hoki te roa o ētahi momo puna, ā, ka taea hoki te whakahaere.
Ka taea hoki te whakarōpū i runga i ō rātou āhua:

Puna papatahi – he mea hanga tēnei momo ki te maitai puna papatahi.
Puna mīhini – ka hangaia tēnei momo puna mā te mīhini rakau pae me te mīhini hurihuri me/te mira rānei, kaua ki te mahi takai. Nā te mea he mīhini, ka whakaurua pea e te puna ngā āhuatanga hei tāpiri atu ki te huānga rapa. Ka taea te hanga i ngā puna mīhini i roto i ngā take kawenga noa o te pēhitanga/toronga, te takahurihuri, me ētahi atu.
Puna nakahi – he waea matotoru e pikopiko ana – e whakamahia whānuitia ana i roto i ngā whakapaipai/taonga whare hou.
