ʻoiai ʻo Nickel 200 a me Nickel 201 he mau mea hoʻohui nickel maʻemaʻe, ʻoi aku ka maikaʻi o ke kūpaʻa o Nickel 201 i nā wahi hoʻemi ma muli o kona haʻahaʻa o ke kalapona. ʻO ke koho ma waena o nā mea ʻelua e pili ana i nā koi noi kikoʻī a me ke kaiapuni e hoʻohana ʻia ai ka mea.
ʻO Nickel 200 a me Nickel 201 he mau metala nickel maʻemaʻe kalepa ʻelua i ʻokoʻa iki i ko lākou hoʻohui kemika.
He mea hoʻohuihui nickel ferromagnetic ka Nickel 200, maʻemaʻe ma ke kālepa (99.6%) me nā waiwai mechanical maikaʻi a me ke kūpaʻa maikaʻi loa i nā ʻano ʻino he nui, me nā waikawa, alkalines, a me nā hopena kūlike ʻole. He haʻahaʻa kona resistivity uila, e kūpono ai no nā noi uila a me nā mea uila.
ʻO Nickel 201, ma ka ʻaoʻao ʻē aʻe, he metala nickel maʻemaʻe nō hoʻi (99.6%) akā he haʻahaʻa ka nui o ke kalapona i hoʻohālikelike ʻia me Nickel 200. ʻO kēia haʻahaʻa o ke kalapona e hāʻawi iā Nickel 201 i ke kūpaʻa maikaʻi i ka palaho i nā wahi hōʻemi, e like me ka sulfuric acid. Hoʻohana pinepine ʻia ia i ka hana kemika, nā ʻāpana uila, a me nā pila hiki ke hoʻouka hou ʻia.
I ka hōʻuluʻulu manaʻo, ʻoiai ʻo Nickel 200 a me Nickel 201 he mau mea hoʻohui nickel maʻemaʻe, ʻoi aku ka maikaʻi o ke kūpaʻa o Nickel 201 i nā wahi hoʻemi ma muli o kona haʻahaʻa o ke kalapona. ʻO ke koho ma waena o nā mea ʻelua e pili ana i nā koi noi kikoʻī a me ke kaiapuni e hoʻohana ʻia ai ka mea.
He nickel alloy hana maʻemaʻe ʻo Nickel200 i hana ʻia me 99.6% nickel. Ua kaulana ia no kona kūpaʻa maikaʻi loa i ka pala, ke alakaʻi wela a me ka uila kiʻekiʻe, ka haʻahaʻa o ke kinoea, a me nā waiwai mechanical maikaʻi. Hiki ke hana maʻalahi ʻia a he haʻahaʻa nā helu kolo, e kūpono ai no nā ʻano hana like ʻole e like me ka hana kemika, nā ʻāpana uila, a me nā wahi kai. ʻAʻole hoʻi he magnetic ʻo Nickel 200 a he kiʻekiʻe kona kiko heheʻe, e pono ai i nā noi wela kiʻekiʻe.
He ʻano metala nickel maʻemaʻe kiʻekiʻe ʻo Nickel201. He metala maʻemaʻe ia no ke kālepa ʻana, ʻo ia hoʻi, aia he 99.6% ka liʻiliʻi o ka nickel, me nā pae haʻahaʻa loa o nā mea ʻē aʻe. Ua kaulana ʻo Nickel 201 no kona kūpaʻa maikaʻi loa i nā ʻano ʻino like ʻole, me nā waikawa, nā hopena alkaline, a me ka wai kai. Hōʻike pū ia i nā waiwai mechanical maikaʻi a me ke alakaʻi wela a me ka uila kiʻekiʻe.
ʻO kekahi o nā hoʻohana maʻamau o Nickel 201 e komo pū me nā lako hana kemika, nā evaporators caustic, ka hana ʻana i ka waikawa hydrochloric, nā lako lāʻau lapaʻau, ka hana ʻana i nā fiber synthetic, a me ka hana ʻana o ka sodium sulfide. Hoʻohana ʻia nō hoʻi ia i nā ʻoihana uila a me nā mea uila no nā ʻāpana e pono ai ke alakaʻi uila kiʻekiʻe.
Ma keʻano holoʻokoʻa, ua mahalo ʻia ʻo Nickel 201 no kona maʻemaʻe kiʻekiʻe, kūpaʻa maikaʻi loa i ka pala, a me ke kūpaʻa ʻana i ka embrittlement i nā mahana kiʻekiʻe. He koho hilinaʻi ia no nā ʻoihana like ʻole kahi e pono ai kēia mau waiwai.
ʻO kekahi o nā ʻokoʻa koʻikoʻi ma waena o Nickel 200 a me Nickel 201 ʻo ia ka nui o ke kalapona. ʻO ka nui o ke kalapona o Nickel 201 he 0.02%, ʻoi aku ka haʻahaʻa ma mua o ka nui o ke kalapona o 0.15% i loko o Nickel 200. ʻO kēia haʻahaʻa o ke kalapona i loko o Nickel 201 e hāʻawi i ka pale maikaʻi ʻana i ka graphitization, kahi hana e hiki ai ke alakaʻi i ka embrittlement a me ka emi ʻana o ka ikaika a me ke kūpaʻa o ka hopena o ka alloy i nā mahana kiʻekiʻe.
Ma muli o kona maʻemaʻe kiʻekiʻe a me ke kūpaʻa i ka graphitization, hoʻohana pinepine ʻia ʻo Nickel 201 i nā noi e pono ai ka ʻike ʻana i nā mahana kiʻekiʻe a me ka hoʻemi ʻana i nā lewa. Koho pinepine ʻia ma mua o Nickel 200 no kona hiki ke mālama i kona mau waiwai mechanical a me ke kūpaʻa ʻana i ka embrittlement i loko o ia mau ʻano.
He metala maʻalahi a hoʻohana nui ʻia ʻo Nickel ma muli o kona mau waiwai maikaʻi loa, e like me ke kūpaʻa ʻana i ka pala, ke kūpaʻa wela kiʻekiʻe, a me ka conductivity uila. ʻO kekahi o nā hui nickel kaulana ʻo Nickel 200, i ʻike ʻia no kona maʻemaʻe a me ke kūpaʻa kiʻekiʻe i ka pala. Eia nō naʻe, aia kekahi ʻano like ʻole o kēia hui i kapa ʻia ʻo Nickel 201, nona kahi ʻano a me nā waiwai ʻokoʻa iki. Ma kēia ʻatikala, e ʻimi mākou i nā ʻokoʻa ma waena o Nickel 200 a me Nickel 201 a me kā lākou mau noi.
He hui nickel maʻemaʻe ʻo Nickel 200 me ka liʻiliʻi o ka nickel ma 99.0%. Ua kaulana ia no kona kūpaʻa kūikawā i nā ʻano ʻino like ʻole, me nā waikawa, nā hopena alkaline, a me ka wai kai. ʻO kēia ka mea e koho kūpono ai no nā noi kahi e koʻikoʻi ai ke kūpaʻa ʻana i ka corrosion, e like me ka hana kemika, ka hana meaʻai, a me nā ʻoihana moana. Eia kekahi, hōʻike ʻo Nickel 200 i ka conductivity thermal a me ka uila maikaʻi loa, e kūpono ana no nā ʻāpana uila a me nā mea uila, a me nā mea hoʻololi wela a me nā noi wela kiʻekiʻe.
Eia nō naʻe, ʻoiai kona kūpaʻa maikaʻi loa i ka palaho, hiki i ka Nickel 200 ke palupalu a hoʻemi ʻia ka ikaika o ka hopena ke hōʻike ʻia i nā mahana ma luna o 600°C, ʻoi aku hoʻi i nā wahi hoʻēmi i loaʻa nā pūhui sulfur a sulfur paha. ʻO kēia kahi e komo mai ai ʻo Nickel 201.
He hui nickel maʻemaʻe nō hoʻi ʻo Nickel 201, me ka haʻahaʻa iki o ke kalapona i hoʻohālikelike ʻia me Nickel 200. ʻO ka nui o ke kalapona no Nickel 201 he 0.02%, ʻoiai ʻo Nickel 200 he 0.15% ka nui o ke kalapona. Hāʻawi kēia ʻike kalapona i hoʻemi ʻia i loko o Nickel 201 i ka pale ʻana i ka graphitization, kahi hana o ka hana ʻana i nā ʻāpana kalapona e hiki ke hoʻemi i ka ikaika a me ka paʻakikī o ka hui i nā mahana kiʻekiʻe. ʻO ka hopena, makemake pinepine ʻia ʻo Nickel 201 ma mua o Nickel 200 i nā noi e koi ana i ka ʻike ʻana i nā mahana kiʻekiʻe a me ka hoʻemi ʻana i nā lewa.
ʻO ke kūpaʻa ʻana i ka graphitization e kūpono loa ai ʻo Nickel 201 no nā noi e pili ana i nā evaporators caustic, ka hana ʻana o ka hydrochloric acid, a me nā lako hana kemika ʻē aʻe. Loaʻa iā ia nā noi ma ka ʻoihana pulp a me ka pepa, a me ka hana ʻana o ka fiber synthetic a me ka sodium sulfide. Eia kekahi, ʻaʻole magnetic ʻo Nickel 201 a kaʻana like i nā waiwai maikaʻi loa e like me Nickel 200, e like me ke kūpaʻa kiʻekiʻe o ka corrosion, ka conductivity thermal, a me ka conductivity uila.
ʻO ke koho ʻana ma waena o Nickel 200 a me Nickel 201 e pili ana i nā koi kikoʻī o ka noi. Inā ʻo ke kūpaʻa ʻana i ka palaho ke kumu nui a ʻaʻole ʻoi aku ka mahana o ka hana ma mua o 600°C, he koho maikaʻi loa ʻo Nickel 200. ʻAʻole pilikia kona ʻike kalapona kiʻekiʻe i ka hapa nui o nā noi, a hāʻawi ia i kahi hopena kūpono no nā ʻoihana he nui. Eia nō naʻe, inā pili ka noi i nā mahana kiʻekiʻe a i ʻole ka hoʻemi ʻana i nā lewa kahi e hiki ai ke hana ʻia ka graphitization, pono e noʻonoʻo ʻia ʻo Nickel 201 no kona kūpaʻa i hoʻonui ʻia i kēia hanana.
He mea nui e kūkākūkā me nā loea o ka ʻoihana, e like me nā ʻenekinia mea a i ʻole nā metallurgists, e hoʻoholo i ka nickel alloy kūpono loa no kahi noi kikoʻī. Hiki iā lākou ke noʻonoʻo i nā mea e like me ke kaiapuni hana, ka mahana, a me nā hopohopo e pili ana i ka embrittlement a i ʻole graphitization. Me ko lākou ʻike, hiki iā lākou ke alakaʻi i nā mea hoʻohana i ka hana ʻana i ke koho kūpono no ka hana maikaʻi loa a me ke ola lōʻihi.
I ka hopena, ʻo Nickel 200 a me Nickel 201 he mau mea hoʻohui nickel maikaʻi loa me nā ʻokoʻa iki i ka haku mele ʻana a me nā waiwai. Hāʻawi ʻo Nickel 200 i ke kūpaʻa ʻana i ka pala a me ka conductivity uila, ʻoiai ʻo Nickel 201 e hāʻawi i ka pale ʻana i ka graphitization i nā mahana kiʻekiʻe a me ka hoʻemi ʻana i nā lewa. ʻO ke koho ʻana i ka mea hoʻohui kūpono no kahi noi kikoʻī e pili ana i nā kūlana hana a me nā waiwai i makemake ʻia, a ua ʻōlelo ʻia ka ʻōlelo aʻoaʻo loea e hōʻoia i ka hana maikaʻi loa. Inā he Nickel 200 a i ʻole Nickel 201, ke hoʻomau nei ka hoʻohana nui ʻia ʻana o kēia mau mea hoʻohui i nā ʻoihana like ʻole no ko lākou versatility a me ka hilinaʻi.
