Hoʻohana ʻia ka Alloy Nickel-based me ka Passivation
Nā ʻano maʻamau o nā huila nikela
E hui maʻalahi ka Nickel me ka nui o nā metala e like me ke keleawe, chromium, hao, a me ka molybdenum.ʻO ka hoʻohui ʻana o ka nickel i nā metala ʻē aʻe e hoʻololi i nā waiwai o ka alloy i loaʻa a hiki ke hoʻohana ʻia e hana i nā hiʻohiʻona i makemake ʻia e like me ka hoʻomaikaʻi ʻana i ka corrosion a i ʻole ke kūpaʻa oxidation, hoʻonui i ka hana wela kiʻekiʻe, a i ʻole nā coefficient haʻahaʻa o ka hoʻonui wela, no ka laʻana.
Hōʻike nā ʻāpana ma lalo nei i ka ʻike e pili ana i kēlā me kēia ʻano o nā ʻāpana nickel.
Nikela-Hao Alloys
Hana ʻia nā alloys Nickel-iron i nā noi kahi i makemake ʻia ai kahi haʻahaʻa haʻahaʻa o ka hoʻonui wela.ʻO Invar 36®, kūʻai pū ʻia me nā inoa kālepa o Nilo 6® a i ʻole Pernifer 6®, hōʻike i kahi koena o ka hoʻonui wela e pili ana i ka 1/10 o ke kila kalapona.ʻO kēia kūlana kiʻekiʻe o ke kūpaʻa dimensional e hoʻohana pono i nā alloy nickel-iron i nā noi e like me nā lako ana pololei a i ʻole nā lāʻau thermostat.Hoʻohana ʻia nā ʻāpana nickel-hao ʻē aʻe me ka ʻoi aku ka nui o ka nickel i nā noi i mea nui nā waiwai magnetic palupalu, e like me nā transformers, inductors, a i ʻole nā mea hoʻomanaʻo hoʻomanaʻo.
Nikela-Copper Alloys
Paʻa loa nā ʻāpana nikela-keleawe i ka corrosion e ka wai paʻakai a i ʻole ka wai kai a no laila e loaʻa ai ka hoʻohana ʻana i nā noi kai.No ka laʻana, ʻo Monel 400®, i kūʻai ʻia ma lalo o nā inoa kalepa ʻo Nickelvac® 400 a i ʻole Nicorros® 400, hiki ke loaʻa i ka noi i nā ʻōnaehana paipu moana, nā ʻōpuʻu paila, a me nā kiwi wai kai.ʻO kēia huila e like me ka haʻahaʻa haʻahaʻa o 63% nickel a me 28-34% keleawe.
Nikela-Molybdenum Alloys
Hāʻawi ka Nickel-molybdenum alloys i ke kūpaʻa kemika kiʻekiʻe i nā ʻakika ikaika a me nā mea hoʻemi ʻē aʻe e like me ka waikawa hydrochloric, hydrogen chloride, sulfuric acid, a me ka waikawa phosphoric.ʻO ka mea hoʻonaninani kemika no kahi huila o kēia ʻano, e like me Alloy B-2®, loaʻa ka ʻike o ka molybdenum o 29-30% a me kahi neʻe nickel ma waena o 66-74%.ʻO nā noi e pili ana i nā pumps a me nā valves, gaskets, pressure vessels, heat exchangers, a me nā huahana paipu.
Nikela-Chromium Alloys
Hoʻohanohano ʻia nā alloys Nickel-chromium no ko lākou pale ʻana i ka corrosion kiʻekiʻe, ka ikaika wela kiʻekiʻe, a me ke kūpaʻa uila kiʻekiʻe.No ka laʻana, ʻo ka huila NiCr 70/30, i koho ʻia ʻo Ni70Cr30, Nikrothal 70, Resistohm 70, a me X30H70 he helu heheʻe o 1380oC a me kahi resistivity uila o 1.18 μΩ-m.Hoʻohana ʻia nā mea hoʻomehana e like me nā toasters a me nā mea hoʻomehana pale uila ʻē aʻe i nā ʻāpana nickel-chromium.Ke hana ʻia ma ke ʻano uea, ʻike ʻia lākou ʻo Nichrome® wire.
