Aia ma lalo kahi hoʻohālikelike kikoʻī e kōkua iā ʻoe e koho i ka alloy kūpono no kāu papahana:

1. ʻOkoʻa Kumu: ʻIke Kalapona (ʻO ka "Mea Hoʻokaʻawale Hana")

ʻO ka ʻokoʻa koʻikoʻi ma waena o Ni200 a me Ni201 aia i ka kaohi ʻana i ka ʻike kalapona—ʻo kēia kumu hoʻokahi e kuhikuhi ana i ko lākou hilinaʻi wela kiʻekiʻe a me ka hiki ke hoʻololi i ke kaʻina hana:

lʻO ke kinikini Ni200Me ka nui o ke kalapona o 0.10%, hoʻohālikelike ia i ka mīkini ʻana i ka mahana o ka lumi a me ka hana maʻamau. Eia nō naʻe, i nā mahana ma mua o 600°C, hui pū nā ʻātoma kalapona i loko o ka hui me ka nickel e hana i nā nickel carbides (Ni₃C), kahi e hoʻokahe ʻia ma nā palena o ka palaoa. Ke alakaʻi nei kēia i ka embrittlement intergranular: lilo ka hui i mea palupalu, nalowale ka ductility, a maʻalahi hoʻi e haki ma lalo o ke kaumaha mechanical a i ʻole ka thermal cycling—e kaupalena ana i kona hoʻohana ʻana i nā wahi wela kiʻekiʻe.

lNi201 AlloyMa ka hoʻopaʻa paʻa ʻana i ke kalapona i ≤0.02%, hoʻopau ia i ka ua carbide ʻoiai ma 750°C. Mālama ka ʻike kalapona haʻahaʻa loa i ke kūpaʻa o ka ʻano palaoa o ka alloy, e hōʻoiaʻiʻo ana i ka ductility mau a me ka ikaika mechanical i ka wā lōʻihi o ka lawelawe wela kiʻekiʻe. ʻO kēia ka mea e koho ai no nā noi e pono ai ka lōʻihi o ka wela.

2. Ke kū'ē ʻana i ka mahana a me ka hoʻololi ʻana i ke ʻano o ka Alloy

ʻOi aku ka maikaʻi o nā mea hoʻohuihui ʻelua i ke kūpaʻa ʻana i ka pala, akā ʻokoʻa loa ko lākou mau palena mahana a me ke kūpono no nā ʻano mea hoʻohuihui like ʻole:

lʻO ke kinikini Ni200: Hoʻonohonoho pono ʻia no nā hiʻohiʻona mahana haʻahaʻa a waena (≤650°C), ʻālohilohi ia i nā noi kahi i hoʻonohonoho mua ʻia ai ka conductivity uila a me ka hiki ke hana i ka mahana o ka lumi. Ma ke ʻano he mau uea, kūpono ia no nā pā pila (lithium-ion, mau pila lead-acid) a me nā mea hoʻohui microelectronic—ʻo kona conductivity kiʻekiʻe (0.069 Ω·mm²/m) e hōʻemi ana i ka nalowale o ka ikehu, ʻoiai ʻo kona ductility kūikawā (≥40%) e ʻae i ka huki ʻana i loko o nā uea ultra-fine (a hiki i ka 0.005mm) a i ʻole nā ​​​​​​kūlou paʻakikī. Ma ke ʻano he mau pepa a i ʻole nā ​​​​​​paipu, hoʻohana ʻia ia i loko o nā pahu mālama kemika haʻahaʻa a me nā lako cryogenic, kahi e kī ai ke kūpaʻa ʻana i ka corrosion a me ke ʻano anu.

lNi201 Alloy: Hoʻolālā ʻia no ka lawelawe wela kiʻekiʻe (600°C–750°C), ʻoi aku ka maikaʻi ma nā wahi ʻino. Ma ke ʻano he mau uea, hoʻoikaika ia i nā mea hoʻomehana umu ʻoihana a me nā electrodes wili—ʻo kona kūpaʻa wela kiʻekiʻe e hōʻoiaʻiʻo i ke ola lawelawe lōʻihi (8,000+ hola i ka hoʻomehana mau ʻana). Ma ke ʻano he mau pepa a i ʻole nā ​​​​paipu, hoʻolaha ʻia ia i loko o nā paipu hana kemika (e lawelawe ana i nā waikawa wela kiʻekiʻe) a me nā ʻāpana kūkulu aerospace, kahi e koʻikoʻi ai ke kūʻē ʻana i ka luhi wela a me nā lewa corrosive. Hoʻopau kona hiki ke weld i ka pono no ka annealing post-weld, e hoʻomaʻamaʻa ana i ka hana ʻana o nā ʻāpana nui.

3. Nā ʻano hana a me ka pono hana

lʻO ke kinikini Ni200ʻO kona ʻike kalapona kiʻekiʻe e hoʻonui i ka mīkini ma ka mahana o ka lumi—ʻoi aku ka maʻalahi o ke kaʻina hana ʻoki, wili, a me ke kahakaha ʻana, e hōʻemi ana i ka ʻaʻahu o nā mea hana a me ka manawa hana. ʻO kēia ka mea e kūpono ai ke kumukūʻai no nā ʻāpana i hana nui ʻia e like me nā pā pila a me nā hale sensor haʻahaʻa. Eia nō naʻe, pono ka hoʻoheheʻe ʻana o Ni200 ma hope o ka hoʻoheheʻe ʻana e hōʻoluʻolu i ke kaumaha kūloko a wehe i ka hoʻokumu ʻana o ka carbide i nā hui hoʻoheheʻe, e hoʻohui ana i kahi hana hana no nā noi wela kiʻekiʻe.

lNi201 AlloyʻOiai ʻo kona haʻahaʻa kalapona e hōʻemi iki ana i ka mīkini ʻana i ka mahana o ka lumi (hiki ke hoʻopili ʻia ka mea hana), ʻoi aku ka maikaʻi ma nā kaʻina hana hoʻokumu wela kiʻekiʻe (e like me ka ʻōwili wela, forging). ʻO kona weldability kiʻekiʻe he mea hoʻololi pāʻani: mālama nā hui weld i ka ikaika a me ka ductility me ka ʻole o ka mālama wela, e ʻoki ana i nā pōʻaiapuni hana no nā ʻāpana nui e like me nā pipelines kemika a i ʻole nā ​​​​ʻāpana aerospace. No nā noi e pili ana i ka welding a i ʻole ke kūkulu ʻana i ka mahana kiʻekiʻe, hāʻawi ʻo Ni201 i ka pono hana kiʻekiʻe a me ka hilinaʻi.

4. Alakaʻi Koho Kūpono a me ke Kumukūʻai

E koho i ka Ni200 Alloy ināPono ʻoe i kahi hopena kūpono no ke kālā no nā noi mahana haʻahaʻa a waena (≤600°C), me ka nānā ʻole i ke ʻano (uea, pepa, paipu). He kūpono ia no:

l Nā mea uila mea kūʻai aku (nā ʻaoʻao pila, nā mea hoʻohui)

Nā lako kemika haʻahaʻa wela (nā pahu mālama, nā paipu haʻahaʻa haʻahaʻa)

l Nā ʻāpana Cryogenic (nā ʻōnaehana lawelawe kinoea wai)

ʻO nā ʻāpana i hana nui ʻia e koi ana i ka mīkini ʻana i ka mahana o ka lumi

E koho i ka Ni201 Alloy ināʻO kāu papahana e pili ana i nā mahana kiʻekiʻe (600°C–750°C), ka hoʻoheheʻe ʻana, a i ʻole nā ​​​​​​wahi ʻino—ʻoiai me kahi kumukūʻai liʻiliʻi, hāʻawi ia i ka waiwai lōʻihi. He kūpono ia no:

l Hoʻomehana ʻoihana (nā ʻōwili wela kiʻekiʻe, nā mea umu)

l Hana kemika (nā paipu waikawa wela kiʻekiʻe, nā liner reactor)

l Aerospace a me ka pale kaua (nā ʻāpana kūkulu wela kiʻekiʻe, nā pahu sensor)

Nā ʻaha kūkā i hoʻopaʻa ʻia (ʻaʻohe pono o ka mālama wela ma hope o ka hoʻopaʻa ʻana)

Hōʻuluʻulu manaʻo

He mau mea hoʻohui nickel maʻemaʻe kiʻekiʻe ʻo Ni200 a me Ni201, akā ʻo ko lākou ʻokoʻa o ke kalapona e hana i nā ikaika ʻokoʻa. ʻO Ni200 ke koho waiwai, hiki ke hoʻohana ʻia no nā noi haʻahaʻa wela, mīkini, a i ʻole nā ​​​​​​hana conductive ma nā ʻano uea, pepa, a me nā paipu. ʻO Ni201 ke koho premium no nā hiʻohiʻona wela kiʻekiʻe, welded, a i ʻole nā ​​​​​​kūlana pale i ka corrosion, kahi e hōʻoia ai ka hilinaʻi a me ke kūpaʻa i ka piʻi iki ʻana o ke kumukūʻai.

Hāʻawi kā mākou hui iā Ni200 a me Ni201ma nā ʻano he nui (nā uea: 0.005mm–5.0mm; nā pepa: 0.1mm–10mm; nā paipu: 1mm–50mm OD) a me nā lawelawe hana maʻamau. Hāʻawi kā mākou hui loea i ke kūkākūkā koho mea manuahi e hōʻoia i kāu koho alloy e kūlike me nā koi hana a me ka waihona kālā. E hilinaʻi i kā mākou nickel alloys no ka maikaʻi mau i nā mea uila, nā kemika, aerospace, a ma waho aku.
