ʻO ka mea NiCr, pōkole no ka nickel-chromium alloy, he mea maʻalahi a me ka hana kiʻekiʻe i hoʻohanohano ʻia no kona hui pū ʻana o ka pale wela, ka pale ʻana i ka corrosion, a me ka conductivity uila. ʻO ka nickel (maʻamau 60-80%) a me ka chromium (10-30%), me nā ʻano mea e like me ka hao, silicon, a i ʻole manganese e hoʻomaikaʻi i nā waiwai kikoʻī.Nā huila NiCrua lilo i mea nui i nā ʻoihana mai ka aerospace a hiki i ka uila—a ua hana ʻia kā mākou huahana NiCr e hoʻohana i kēia mau ikaika i ka piha.

ʻO ke kumu o ka hoʻopiʻi ʻana a NiCr kona kūpaʻa kiʻekiʻe kiʻekiʻe. ʻAʻole like me nā metala he nui i hoʻopalupalu a oxidize i ka wā e ʻike ʻia ai i ka wela loa, mālama nā alloys NiCr i ko lākou ikaika mechanical a me ka kūpaʻa o ke kūkulu ʻana i nā mahana ma mua o 1,000°C. ʻO kēia ma muli o ka chromium maʻiʻo, ka mea i hoʻokumu i kahi ʻāpana oxide pale ma luna o ka ʻili, e pale ana i ka oxidation a me ka degradation. ʻO kēia ka mea e kūpono ai ʻo NiCr no nā noi e like me nā mea hoʻomehana umu ahi, nā ʻāpana ʻenekini jet, a me nā kiln ʻoihana, kahi hiki ʻole ke pale ʻia ka hoʻomau ʻana i ka wela kiʻekiʻe.

ʻO ke kūpaʻa corrosion kekahi mea nui. ʻOi aku ka maikaʻi o nā alloys NiCr i ka pale ʻana i ka hoʻouka ʻana mai nā kaiapuni oxidizing, me ka ea, ka mahu, a me kekahi mau mea kemika. He mea waiwai kēia waiwai i nā mea kanu hoʻoponopono kemika, kahi e hoʻohana ʻia ai i nā mea hoʻololi wela, nā reactors, a me nā ʻōnaehana paipu e mālama i ka media corrosive. ʻAʻole like me nā metala maʻemaʻe a i ʻole nā ​​​​mea hoʻoheheʻe ikaika ʻole, pale nā ​​mea NiCr i ka pitting, scaling, a me ka ʻōpala, e hōʻoia ana i ka hilinaʻi lōʻihi a me ka hōʻemi ʻana i nā kumukūʻai mālama.

ʻO ka conductivity uila ke kolu o nā hiʻohiʻona koʻikoʻi. ʻOiai ʻaʻole e like me ka conductive e like me ke keleawe maʻemaʻe, hāʻawi nā alloys NiCr i kahi kaulike kūʻokoʻa o ka conductivity a me ke kūpaʻa wela, e hoʻomaʻamaʻa iā lākou no nā mea hoʻomehana i nā mea hana, nā mea hoʻomehana ʻoihana, a me nā mea pale uila. ʻO ko lākou hiki ke hana a puʻunaue like i ka wela me ka ʻole o ka hoʻohaʻahaʻa ʻana e hōʻoia i ka hana maʻamau i nā mea like me nā toasters, nā mea maloʻo lauoho, a me nā umu ʻoihana.

Hoʻolālā ʻia kā mākou huahana NiCr e hoʻonui i kēia mau pono. Hāʻawi mākou i nā ʻano hana like ʻole, mai nā huila nickel kiʻekiʻe no ka pale ʻana i ka wela loa i nā ʻano like ʻole chromium-rich i hoʻopaʻa ʻia no ka pale ʻana i ka corrosion. Loaʻa i nā ʻano e like me nā uea, nā lipine, nā ʻāpana, a me nā ʻāpana maʻamau, hana ʻia kā mākou huahana me ka hoʻohana ʻana i nā ʻenehana holomua e hōʻoia i ka hoʻohui like ʻana a me ka pololei dimensional. Hōʻoia ka hoʻāʻo maikaʻi ʻana i kēlā me kēia ʻāpana i nā kūlana ʻoihana, inā no nā ʻāpana aerospace a i ʻole nā ​​mea hoʻomehana i kēlā me kēia lā.

Inā makemake ʻoe i kahi mea hiki ke kū i ka paʻakikī o nā kaʻina hana ʻenehana kiʻekiʻe a i ʻole e pale i ka corrosion i loko o nā wahi kemika koʻikoʻi,kā mākou huahana NiCrhāʻawi i ka hana a me ka lōʻihi āu e hilinaʻi ai. Me nā hoʻonā kūpono no nā noi like ʻole, ua kūpaʻa mākou i ka hāʻawi ʻana i nā mea NiCr e hoʻokiʻekiʻe i ka pono a me ka lōʻihi o kāu mau papahana.
