ʻO ka Ferro niobium he mea hoʻoheheʻe metala, ʻo kāna mau mea nui he niobium a me ka hao, he wahi hoʻoheheʻe kiʻekiʻe, kūpaʻa oxidation a me ke kūpaʻa corrosion. Hoʻohana maʻamau ʻia nā alloys Niobium i ka hana ʻana i nā mea mīkini a me nā mea uila i nā wela kiʻekiʻe. Eia nā noi a me nā pono o ka niobium ferroalloy:
Noi:
1. ʻO ka hoʻolālā wela kiʻekiʻe: hiki ke hana ʻia ka niobium ferroalloy me ka impeller, alakaʻi i ka pahi a me ka nozzle a me nā ʻāpana ʻē aʻe o ka turbine mahu.
2. Nā mea uila uila lahilahi: hiki ke hoʻohanaʻia ka ferroniobium alloy e hana i nā kiʻiʻoniʻoni magnetic, i hoʻohanaʻia i loko o nā mea uila e like me nā meaʻike magnetic, ka hoʻomanaʻo a me nā meaʻike.
Pono:
1. ʻO ke kūpaʻa wela kiʻekiʻe: Hiki i ka Niobium alloy ke mālama i kona ʻano a me nā waiwai mechanical ma lalo o ke kaiapuni wela.
2. ʻO ke kūpaʻa o ka oxidation: hiki i ka ferroniobium alloy ke hana i kahi pale pale oxide paʻa i ke kiʻekiʻe o ka wela wela, e hoʻolōʻihi i ke ola lawelawe o ka alloy.
3. Ke kū'ēʻana i ke kino: Hiki i ka Niobium ferroalloy ke kū'ē i ke kino a me ka electrochemical corrosion, a he maikaʻi ke kūpaʻa wela a me ka paleʻana.
