Ahakoa he koranu nikara parakore te Nikara 200 me te Nikara 201, he pai ake te ātete o te Nikara 201 ki ngā taiao whakaiti nā te iti o te ihirangi waro. Ko te kōwhiringa i waenga i ngā mea e rua ka whakawhirinaki ki ngā whakaritenga tono motuhake me te taiao e whakamahia ai te rauemi.
He koranu nikara parakore arumoni te Nikara 200 me te Nikara 201, he rerekē paku te hanganga matū.
He koranu nikara ferromagnetic te Nikara 200, he parakore ā-pākihi (99.6%), he pai ōna āhuatanga hangarau, ā, he tino ātete ki ngā taiao waikura maha, tae atu ki ngā waikawa, ngā kawakore, me ngā otinga kūpapa. He iti tōna ātete hiko, ā, he pai mō ngā mahi hiko me ngā mahi hiko.
Ko te Nikara 201, i tētahi atu taha, he koranu nikara parakore hoki mō te hokohoko (99.6%) engari he iti ake te ihirangi waro i te Nikara 200. Nā tēnei ihirangi waro iti ake ka pai ake te ātete o te Nikara 201 ki te waikura i roto i ngā taiao whakaiti, pērā i te waikawa whanariki. He mea whakamahi noa hoki i roto i te tukatuka matū, ngā wāhanga hiko, me ngā pākahiko ka taea te whakahou.
Hei whakarāpopototanga, ahakoa he koranu nikara parakore te Nikara 200 me te Nikara 201, he pai ake te ātete o te Nikara 201 ki ngā taiao whakaiti nā te iti o te ihirangi waro. Ko te kōwhiringa i waenga i ngā mea e rua ka whakawhirinaki ki ngā whakaritenga tono motuhake me te taiao e whakamahia ai te rauemi.
He koranu nikara parakore arumoni te Nickel200, he 99.6% te nikara kei roto. E mōhiotia ana mō tōna ātete pai ki te waikura, tōna kawe wera me te hiko teitei, tōna ihirangi hau iti, me ōna āhuatanga miihini pai. He ngāwari te hanga, ā, he iti hoki ngā tere ngoki, he pai mō te whānuitanga o ngā tono tae atu ki te tukatuka matū, ngā wāhanga hiko, me ngā taiao moana. Kāore hoki te Nickel 200 i te aukume, ā, he teitei te ira rewa, he pai mō ngā tono pāmahana teitei.
He momo konganuku nikara te Nickel201, he tino parakore. He koranu parakore tēnei mō te hokohoko, arā, he 99.6% te iti rawa o te ihirangi nikara, ā, he iti noa iho ngā taumata o ētahi atu huānga. E mōhiotia ana te Nickel 201 mō tōna ātete pai ki ngā taiao waikura, tae atu ki ngā waikawa, ngā otinga kawakore, me te wai moana. He pai hoki ōna āhuatanga miihini me te kawe hiko me te wera teitei.
Ko ētahi o ngā whakamahinga noa o te Nickel 201 ko ngā taputapu tukatuka matū, ngā mīhini whakapūngāwerewere, te hanga waikawa hauwaiora, ngā taputapu rongoā, te hanga muka hangai, me te hanga konutai whanariki. E whakamahia ana hoki i roto i ngā ahumahi hiko me te hikohiko mō ngā wāhanga e hiahia ana ki te kawe hiko teitei.
I te nuinga o te wā, e whakanuia ana te Nikara 201 mō tōna parakore teitei, tōna ātete pai ki te waikura, me tōna ātete ki te pakarukaru i ngā pāmahana tiketike. He kōwhiringa pono tēnei mō ngā momo ahumahi e hiahiatia ana ēnei āhuatanga.
Ko tētahi o ngā rerekētanga matua i waenga i te Nikara 200 me te Nikara 201 ko te nui o te waro. Ko te nui o te waro o te Nikara 201 he 0.02%, he iti iho i te nui o te waro o te Nikara 200 he 0.15%. Mā tēnei iti o te waro i roto i te Nikara 201 ka pai ake te ātete ki te whakakāwhata, he tukanga ka arahi pea ki te pakarukaru me te whakaiti i te kaha me te ātete pānga o te koranu i ngā pāmahana teitei.
Nā tōna parakore teitei me te ātete nui ake ki te whakakāwhata, e whakamahia whānuitia ana te Nikara 201 i roto i ngā tono e hiahia ana kia pāngia e ngā pāmahana teitei me te whakaiti i ngā āhuarangi. He maha ngā wā ka whiriwhiria i te Nikara 200 nā tōna kaha ki te pupuri i ōna āhuatanga miihini me te ātete ki te pakarukaru i roto i aua taiao.
He konganuku maha ngā whakamahinga o te nikara, ā, he whānui te whakamahinga nā ōna āhuatanga pai rawa atu, pērā i te ātete ki te waikura, te ātete ki te pāmahana teitei, me te kawe hiko. Ko tētahi o ngā koranu nikara rongonui ko te nikara 200, e mōhiotia ana mō tōna parakore me tōna ātete ki te waikura. Heoi, he momo kē atu anō o tēnei koranu e kiia nei ko te nikara 201, he rerekē te hanganga me ōna āhuatanga. I roto i tēnei tuhinga, ka tūhuratia e mātou ngā rerekētanga i waenga i te nikara 200 me te nikara 201 me ā rāua whakamahinga.
He koranu nikara parakore te Nikara 200, ā, ko te iti rawa o te ihirangi nikara he 99.0%. E mōhiotia ana mō tōna ātete tino pai ki ngā taiao waikura, tae atu ki ngā waikawa, ngā otinga kawakore, me te wai moana. Nā tēnei he kōwhiringa pai mō ngā tono e tino nui ana te ātete ki te waikura, pērā i te tukatuka matū, te tukatuka kai, me ngā ahumahi moana. Hei tāpiri, he tino pai te kawe wera me te hiko o te Nikara 200, e pai ai mō ngā wāhanga hiko me ngā wāhanga hiko, tae atu ki ngā whakawhiti wera me ngā tono pāmahana teitei.
Ahakoa tōna ātete pai ki te waikura, ka ngawari te pakarukaru o te Nikara 200, ka heke hoki tōna kaha pānga ina pāngia e ngā pāmahana neke atu i te 600°C, inā koa i roto i ngā taiao whakaitiiti kei roto he whanariki, he pūhui whanariki rānei. Koinei te wāhi e whai hua ai te Nikara 201.
He koranu nikara parakore anō hoki te Nikara 201, he iti ake te ihirangi waro i te Nikara 200. Ko te ihirangi waro mōrahi mō te Nikara 201 he 0.02%, ko te ihirangi waro mōrahi mō te Nikara 200 he 0.15%. Mā tēnei ihirangi waro kua whakaitihia i roto i te Nikara 201 ka pai ake te ātete ki te whakakāwhata, he tukanga hanga matūriki waro ka taea te whakaiti i te kaha me te pakari o te koranu i ngā pāmahana teitei. Nō reira, he pai ake te Nikara 201 i te Nikara 200 i roto i ngā tono e hiahia ana kia pāngia e ngā pāmahana teitei me te whakaiti i ngā hau.
Nā te ātete ki te whakakāwhata, he tino pai te Nickel 201 mō ngā tono e pā ana ki ngā kaiwhakamahana waikura, te hanga waikawa hauwaiora, me ētahi atu taputapu tukatuka matū. Ka kitea hoki ngā tono i roto i te umanga penupenu me te pepa, tae atu ki te hanga muka hangai me te konutai whanariki. Hei tāpiri, kāore te Nickel 201 i te aukume, ā, he rite tonu ngā āhuatanga pai ki te Nickel 200, pērā i te ātete nui ki te waikura, te kawe wera, me te kawe hiko.
Ko te whiriwhiri i waenga i te Nikara 200 me te Nikara 201 e whakawhirinaki ana ki ngā whakaritenga motuhake o te tono. Mena ko te ātete waikura teitei te mea nui, ā, kāore te pāmahana whakahaere e neke ake i te 600°C, he kōwhiringa pai te Nikara 200. Kāore he raruraru o te nuinga o ngā tono nā te nui o te waro, ā, he otinga utu-pai hoki mō te maha o ngā ahumahi. Heoi, mena he pāmahana teitei, he whakaiti rānei i ngā hau e puta ai te whakakāwhata, me whakaaro ki te Nikara 201 mō tōna ātete nui ake ki tēnei āhuatanga.
He mea nui kia kōrero tahi me ngā tohunga o te umanga, pērā i ngā miihini rauemi, ngā tohunga whakarewa rānei, kia mōhio ai koe ki te konukōre nikara e tika ana mō tētahi whakamahinga motuhake. Ka taea e rātou te whakaaro ki ngā āhuatanga pēnei i te taiao mahi, te pāmahana, me ngā āwangawanga pea e pā ana ki te pakarukaru, te whakakāwhatu rānei. Mā ō rātou pūkenga, ka taea e rātou te ārahi i ngā kaiwhakamahi ki te whiriwhiri tika mō te mahi tino pai me te roa o te wā.
Hei whakamutunga, he pai rawa atu ngā konukōre nikara a Nickel 200 me Nickel 201, engari he iti noa ngā rerekētanga o te hanganga me ngā āhuatanga. He tino pai te ātete ki te waikura me te kawe hiko a Nickel 200, ko te Nickel 201 ia he pai ake te ātete ki te whakakāwhata i ngā pāmahana teitei me te whakaiti i ngā āhuarangi. Ko te whiriwhiri i te konukōre tika mō tētahi tono motuhake ka whakawhirinaki ki ngā āhuatanga mahi me ngā āhuatanga e hiahiatia ana, ā, ka tūtohuhia ngā tohutohu a ngā tohunga kia pai ai te mahi. Ahakoa he Nickel 200, he Nickel 201 rānei, kei te whakamahia whānuitia tonutia ēnei konukōre i roto i ngā momo ahumahi nā tō rātou ngāwari me te pono.
