ʻoiai ʻo Nickel 200 a me Nickel 201 he mau nickel alloys maʻemaʻe, ʻoi aku ka maikaʻi o ka Nickel 201 i ka hoʻohaʻahaʻa ʻana i nā kaiapuni ma muli o kāna ʻano kalapona haʻahaʻa. ʻO ka koho ma waena o nā mea ʻelua e hilinaʻi ʻia i nā koi noi kikoʻī a me ke kaiapuni kahi e hoʻohana ʻia ai ka mea.
ʻO Nickel 200 a me Nickel 201 nā ʻāpana nickel maʻemaʻe kālepa i ʻokoʻa iki i kā lākou haku mele.
ʻO Nickel 200 he ferromagnetic, maʻemaʻe maʻemaʻe (99.6%) nickel alloy me nā waiwai mechanical maikaʻi a me ke kūpaʻa maikaʻi loa i nā kaiapuni corrosive he nui, me nā waikawa, alkalines, a me nā hopena kūʻokoʻa. Loaʻa iā ia ka resistivity uila haʻahaʻa, kūpono ia no ka uila a me nā noi uila.
ʻO Nickel 201, ma ka ʻaoʻao ʻē aʻe, he hui nickel maʻemaʻe hoʻi (99.6%) akā he haʻahaʻa haʻahaʻa ka carbon content i hoʻohālikelike ʻia me Nickel 200. ʻO kēia haʻahaʻa carbon content hāʻawi iā Nickel 201 ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion i ka hoʻohaʻahaʻa ʻana i nā kaiapuni, e like me ka sulfuric acid. Hoʻohana maʻamau ʻia ia i ka hoʻoili kemika, nā ʻāpana uila, a me nā pākaukau rechargeable.
I ka hōʻuluʻulu manaʻo, ʻoiai ʻo Nickel 200 a me Nickel 201 he mau nickel alloys maʻemaʻe, ʻoi aku ka maikaʻi o ka Nickel 201 i ka hoʻohaʻahaʻa ʻana i nā kaiapuni ma muli o kona ʻano kalapona haʻahaʻa. ʻO ka koho ma waena o nā mea ʻelua e hilinaʻi ʻia i nā koi noi kikoʻī a me ke kaiapuni kahi e hoʻohana ʻia ai ka mea.
ʻO Nickel200 kahi hui nickel hana maʻemaʻe maʻemaʻe i loaʻa he 99.6% nickel. Ua ʻike ʻia no kona kūpaʻa corrosion maikaʻi loa, kiʻekiʻe ka wela a me ka conductivity uila, haʻahaʻa haʻahaʻa kinoea, a me nā waiwai mechanical maikaʻi. Hiki ke hana maʻalahi a he haʻahaʻa nā creep rate, kūpono ia no nā ʻano noi like ʻole me ka hoʻoponopono kemika, nā ʻāpana uila, a me nā kaiapuni kai. ʻO Nickel 200 ka mea non-magnetic a he kiʻekiʻe ka helu heheʻe, e hoʻohana pono ai i nā noi wela kiʻekiʻe.
ʻO Nickel201 kahi ʻano maʻemaʻe kiʻekiʻe o ka metala nickel. ʻO ia kahi huila maʻemaʻe kūʻai, ʻo ia hoʻi he 99.6% ka liʻiliʻi o ka nickel content, me nā pae haʻahaʻa loa o nā mea ʻē aʻe. Ua ʻike ʻia ʻo Nickel 201 no kona kūpaʻa maikaʻi ʻana i nā kaiapuni corrosive like ʻole, e komo pū me nā waikawa, nā hopena alkaline, a me ka wai kai. Hōʻike pū ia i nā waiwai mechanical maikaʻi a me ka conductivity wela a me ka uila kiʻekiʻe.
ʻO kekahi mau noi maʻamau o Nickel 201 e pili ana i nā lako hana kemika, nā evaporators caustic, ka hana ʻana i ka waika hydrochloric, nā lako lāʻau lapaʻau, ka hana fiber synthetic, a me ka hana sodium sulfide. Hoʻohana ʻia ia i nā ʻoihana uila a me nā ʻoihana uila no nā ʻāpana e koi ana i ka conductivity uila kiʻekiʻe.
Ma keʻano holoʻokoʻa, waiwai nui ʻo Nickel 201 no kona maʻemaʻe kiʻekiʻe, kūpaʻa maikaʻi i ka corrosion, a me ke kūʻē ʻana i ka embrittlement ma nā wela kiʻekiʻe. He koho hilinaʻi ia no nā ʻoihana like ʻole kahi e koi ʻia ai kēia mau waiwai.
ʻO kekahi o nā ʻokoʻa nui ma waena o Nickel 200 a me Nickel 201 ʻo ia ka ʻike kalapona. Loaʻa i ka Nickel 201 ka nui o ka carbon carbon content o 0.02%, ʻoi aku ka haʻahaʻa ma mua o ka nui o ka carbon carbon content o 0.15% i Nickel 200. ʻO kēia ʻano kalapona i hoʻemi ʻia ma Nickel 201 e hāʻawi i ka hoʻomaikaʻi ʻana i ka graphitization, kahi hana e hiki ai ke alakaʻi i ka embrittlement a hoʻemi i ka ikaika. a me ke kū'ē i ka hopena o ka huila i nā wela kiʻekiʻe.
Ma muli o kona maʻemaʻe kiʻekiʻe a hoʻonui i ke kū'ē i ka graphitization, hoʻohana mau ʻia ʻo Nickel 201 i nā noi e koi ana i ka ʻike ʻana i nā mahana kiʻekiʻe a me ka hoʻohaʻahaʻa ʻana i nā lewa. Ua koho pinepine ʻia ma luna o Nickel 200 no kona hiki ke mālama i kona mau waiwai mechanical a me ke kū'ē i ka embrittlement i loko o ia mau kaiapuni.
ʻO Nickel kahi metala maʻalahi a hoʻohana nui ʻia ma muli o kāna mau waiwai maikaʻi loa, e like me ke kūpaʻa corrosion, ke kūpaʻa wela kiʻekiʻe, a me ka conductivity uila. ʻO kekahi o nā nickel alloys kaulana ʻo Nickel 200, i ʻike ʻia no kona maʻemaʻe a me ke kūpaʻa kiʻekiʻe. Eia nō naʻe, aia kekahi ʻano ʻē aʻe o kēia huila i kapa ʻia ʻo Nickel 201, he ʻano ʻokoʻa a me nā waiwai. Ma kēia ʻatikala, e ʻimi mākou i nā ʻokoʻa ma waena o Nickel 200 a me Nickel 201 a me kā lākou mau noi.
ʻO Nickel 200 kahi hui nickel maʻemaʻe me ka liʻiliʻi o 99.0%. ʻIke ʻia ʻo ia no kona kū kūʻē kūʻokoʻa i nā kaiapuni corrosive like ʻole, me nā waikawa, nā hopena alkaline, a me ka wai kai. He koho maikaʻi kēia no nā noi kahi koʻikoʻi ka pale ʻana i ka corrosion, e like me ka hana kemika, ka hana ʻai, a me nā ʻoihana kai. Hoʻohui hou, hōʻike ʻo Nickel 200 i ka conductivity thermal a me ka uila maikaʻi loa, kūpono ia no nā mea 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 ʻana i ka corrosion, hiki i ka Nickel 200 ke hiki ke hoʻomāliʻi a hoʻemi ʻia ka ikaika o ka hopena ke ʻike ʻia i nā mahana ma luna o 600 ° C, ʻoi aku hoʻi i ka hoʻohaʻahaʻa ʻana i nā kaiapuni i loaʻa i ka sulfur a i ʻole nā pūhui sulfur. ʻO kēia kahi e pāʻani ai ʻo Nickel 201.
ʻO Nickel 201 kekahi mea nickel alloy maʻemaʻe, me ka haʻahaʻa haʻahaʻa haʻahaʻa i hoʻohālikelike ʻia me Nickel 200. ʻO ka nui o ke kalapona kalapona no Nickel 201 ʻo 0.02%, ʻoiai ʻo Nickel 200 he 0.15%. Hāʻawi kēia ʻano kalapona i hoʻemi ʻia ma Nickel 201 i ka hoʻomaikaʻi ʻana i ke kūʻē ʻana i ka graphitization, kahi hana o ka hana ʻana i nā ʻāpana kalapona e hiki ke hōʻemi i ka ikaika a me ka paʻakikī o ka alloy ma nā wela 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 hoʻohaʻahaʻa ʻana i nā lewa.
ʻO ke kū'ē i ka graphitization e kūpono loa i ka Nickel 201 no nā noi e pili ana i nā evaporators caustic, hydrochloric acid production, a me nā mea hana kemika ʻē aʻe. Loaʻa iā ia nā noi i ka pulp a me ka ʻoihana pepa, a me ka hana ʻana i ka fiber synthetic a me ka sodium sulfide. Eia hou, ʻo Nickel 201 ʻaʻole magnetik a kaʻana like i nā waiwai maikaʻi loa e like me Nickel 200, e like me ke kūpaʻa kiʻekiʻe o ka corrosion, 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 ʻoi aku ka nui o ka pale ʻana i ka corrosion ka mea nui a ʻaʻole ʻoi aku ka mahana o ka hana ma mua o 600°C, ʻo Nickel 200 kahi koho maikaʻi loa. ʻAʻole hoʻopiʻi kona ʻike kalapona kiʻekiʻe i ka hapa nui o nā noi, a hāʻawi ia i kahi hopena maikaʻi loa no nā ʻoihana he nui. Eia nō naʻe, inā pili ka noi i nā wela kiʻekiʻe a i ʻole ka hoʻohaʻahaʻa ʻana i nā lewa kahi e hiki mai ai ka graphitization, pono e noʻonoʻo ʻia ʻo Nickel 201 no kona hoʻoikaika ʻana i kēia ʻano.
Pono e kūkākūkā me nā poʻe ʻoihana ʻoihana, e like me nā mea ʻenekinia waiwai a me nā metallurgists, e hoʻoholo ai 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 pilikia e pili ana i ka embrittlement a i ʻole graphitization. Me ko lākou akamai, hiki iā lākou ke alakaʻi i nā mea hoʻohana i ke koho kūpono no ka hana maikaʻi loa a me ka lōʻihi.
I ka hopena, ʻo Nickel 200 a me Nickel 201 nā ʻāpana nickel maikaʻi loa me nā ʻokoʻa liʻiliʻi o ka haku mele ʻana a me nā waiwai. Hāʻawi ʻo Nickel 200 i ka pale ʻana i ka corrosion a me ka conductivity uila, ʻoiai ʻo Nickel 201 e hāʻawi i ka pale ʻana i ka graphitization ma nā wela kiʻekiʻe a me ka hoʻohaʻahaʻa ʻana i nā lewa. ʻO ke koho ʻana i ka alloy kūpono no kahi noi kūikawā e pili ana i nā kūlana hana a me nā waiwai i makemake ʻia, a ʻōlelo ʻia nā ʻōlelo aʻoaʻo loea e hōʻoia i ka hana maikaʻi loa. Inā ʻo Nickel 200 a i ʻole Nickel 201, hoʻohana nui ʻia kēia mau ʻāpana i nā ʻoihana like ʻole no kā lākou versatility a me ka hilinaʻi.
