ʻO ka mea NiCr, pōkole no ka nickel-chromium alloy, he mea hana maʻalahi a kiʻekiʻe hoʻi i kaulana no kona hui pū ʻana o ke kūpaʻa wela, ke kūpaʻa ʻana i ka pala, a me ka conductivity uila. Hana ʻia me ka nickel (maʻamau 60-80%) a me ka chromium (10-30%), me nā mea trace e like me ka hao, silicon, a i ʻole manganese e hoʻonui i nā waiwai kikoʻī,Nā mea hoʻohui NiCrua lilo i mea nui loa i nā ʻoihana mai ka aerospace a i nā mea uila—a ua hana ʻia kā mākou huahana NiCr e hoʻohana pono i kēia mau ikaika.

ʻO ke kumu o ka hoʻopiʻi ʻana o NiCr ʻo ia kona kūpaʻa kiʻekiʻe i ka mahana. ʻAʻole e like me nā metala he nui e palupalu a oxide paha i ka wā e hōʻike ʻia ai i ka wela nui, mālama nā alloys NiCr i ko lākou ikaika mechanical a me ke kūpaʻa kūkulu ʻana i nā mahana ma mua o 1,000°C. ʻO kēia ma muli o ka ʻike chromium, kahi e hana ai i kahi papa oxide mānoanoa a pale ma luna o ka ʻili, e pale ana i ka oxidation a me ka degradation hou aʻe. ʻO kēia ka mea e kūpono ai ʻo NiCr no nā noi e like me nā mea hoʻomehana umu, nā ʻāpana mīkini jet, a me nā umu ʻoihana, kahi e hiki ʻole ai ke pale ʻia ka hoʻomau ʻana i ka wela kiʻekiʻe.

ʻO ke kūpaʻa ʻana i ka palaho kekahi ʻano koʻikoʻi. He ʻoi aku ka maikaʻi o nā mea hoʻohuihui NiCr i ke kūʻē ʻana i ka hoʻouka ʻana mai nā wahi oxidizing, me ka ea, ka mahu, a me kekahi mau kemika. ʻO kēia waiwai ka mea e waiwai ai lākou i nā hale hana kemika, kahi e hoʻohana ʻia ai lākou i nā mea hoʻololi wela, nā reactors, a me nā ʻōnaehana paiping e lawelawe ana i nā media corrosive. ʻAʻole e like me nā metala maʻemaʻe a i ʻole nā ​​​​mea hoʻohuihui ikaika ʻole, kūʻē nā mea NiCr i ka pitting, scaling, a me ka popo, e hōʻoiaʻiʻo ana i ka hilinaʻi lōʻihi a me ka hōʻemi ʻana i nā kumukūʻai mālama.

ʻO ke alakaʻi uila kahi hiʻohiʻona koʻikoʻi ʻekolu. ʻOiai ʻaʻole like ka alakaʻi me ke keleawe maʻemaʻe, hāʻawi nā hui NiCr i kahi kaulike kūikawā o ka conductivity a me ke kūpaʻa wela, e kūpono ai lākou no nā mea hoʻomehana i nā mīkini, nā mea hoʻomehana ʻoihana, a me nā mea pale uila. ʻO ko lākou hiki ke hoʻoulu a hāʻawi like i ka wela me ka ʻole o ka hōʻino ʻana e hōʻoia i ka hana mau i nā hāmeʻa e like me nā toasters, nā mea hoʻomaloʻo lauoho, a me nā umu ʻoihana.

Ua hoʻolālā ʻia kā mākou huahana NiCr e hoʻonui i kēia mau pono. Hāʻawi mākou i nā ʻano hoʻohuihui like ʻole, mai nā mea hoʻohuihui nickel kiʻekiʻe no ke kūpaʻa wela loa a hiki i nā ʻano waiwai chromium i hoʻomaikaʻi ʻia no ka pale ʻana i ka pala. Loaʻa i nā ʻano e like me nā uea, nā lipine, nā pepa, a me nā ʻāpana maʻamau, ua hana pololei ʻia kā mākou huahana me ka hoʻohana ʻana i nā ʻenehana holomua e hōʻoia i ka haku mele like a me ka pololei o ka dimensional. Hōʻoia ka hoʻāʻo maikaʻi koʻikoʻi e hoʻokō kēlā me kēia ʻāpana i nā kūlana ʻoihana, inā no nā ʻāpana aerospace-grade a i ʻole nā ​​​​mea hoʻomehana o kēlā me kēia lā.

Inā ʻoe e makemake i kahi mea e hiki ke kū i nā pilikia o nā kaʻina hana ʻoihana wela kiʻekiʻe a i ʻole e kūʻē i ka pala i nā wahi kemika ʻino,kā mākou huahana NiCrhāʻawi i ka hana a me ke kūpaʻa hiki iā ʻoe ke hilinaʻi. Me nā hoʻonā i hoʻopilikino ʻia no nā noi like ʻole, ua kūpaʻa mākou i ka hāʻawi ʻana i nā mea NiCr e hoʻokiʻekiʻe i ka pono a me ke ola lōʻihi o kāu mau papahana.
