Mtengo Wa Factory Gulitsani Niobium Powder ndi Nb ndi CAS No 7440-03-1 High-Entropy Alloys(HEA)

superalloy

Gawo lalikulu la dziko lapansi la niobium limagwiritsidwa ntchito popanga faifi tambala, chromium ndi ma superalloys opangidwa ndi chitsulo mu mawonekedwe azitsulo kapena ngati mawonekedwe a ferric niobium ndi niobium nickel alloys. Ma alloys awa amagwiritsidwa ntchito mu injini za jet, injini za turbine zamagesi, zida za rocket, ma turbocharger ndi zida zoyaka zosagwira kutentha. Niobium ipanga gawo la y mu kapangidwe ka tirigu wa superalloy. Ma alloys awa amakhala ndi niobium mpaka 6.5%. Aloyi ya Incone1718 ndi imodzi mwazitsulo za niobium-nickel based alloys, zomwe zili mu chinthu chilichonse ndi: nickel 50%, chromium 18.6%, iron 18.5%, niobium 5%, key 3.1%, titaniyamu 0.9% ndi aluminium 0.4%. Mapulogalamuwa akuphatikiza ngati zida zapamwamba za airframe, monga zomwe zidagwiritsidwa ntchito mu Project Gemini.

Niobium base alloy

C-103 ndi niobium aloyi munali 89% niobium, 10% hafnium ndi 1% titaniyamu, amene angagwiritsidwe ntchito mu madzi rocket propulsion nozzles, monga injini yaikulu ya gawo mwezi wa Apollo. Gawo lautumiki la Apollo limagwiritsa ntchito aloyi yasiliva yosiyana. Popeza niobium imayamba kutulutsa oxidize pamwamba pa 400 ° C, kuti zisawonongeke, ziyenera kugwiritsidwa ntchito pamwamba pake.

Niobium imagwiranso ntchito yofunika kwambiri pamankhwala opangira opaleshoni, sikuti imangogwiritsidwa ntchito popanga zida zamankhwala, komanso ndi "biological adaptive material", chifukwa imakhala ndi kukana kwambiri kwa dzimbiri, sikungagwirizane ndi zinthu zosiyanasiyana zamadzimadzi m'thupi la munthu. , ndipo pafupifupi zonse siziwononga minyewa ya thupi, chifukwa njira iliyonse yolera imatha kusinthidwa. Chifukwa chake imatha kumangirira ku minofu ya organic kwa nthawi yayitali ndikukhalabe wopanda vuto m'thupi.
