Mutengo Wemufekitari Tengesa Niobium Powder neNb uye CAS No 7440-03-1 Yakakwira-Entropy Alloys(HEA)

superalloy

Chikamu chikuru cheniobium yenyika chinoshandiswa mukugadzira nickel, chromium uye iron-based superalloys mu pure metallic form kana muchimiro chepamusoro kuchena ferric niobium uye niobium nickel alloys. Aya ma alloys anoshandiswa mumajini ejeti, injini dze turbine yegasi, zvinhu zveroketi, maturbocharger uye zvigadziriso zvinopisa zvinopisa. Niobium ichaumba y chikamu muchimiro chezviyo che superalloy. Aya ma alloys anowanzo aine inosvika 6.5% niobium. Incone1718 alloy imwe ye niobium-nickel based alloys, zviri mukati mechimwe nechimwe chinhu ndeichi: nickel 50%, chromium 18.6%, iron 18.5%, niobium 5%, key 3.1%, titanium 0.9% uye 0.4%. Zvikumbiro zvinosanganisira seyepamusoro-yekupedzisira airframe zvinhu, seyakashandiswa muProjekti Gemini.

Niobium base alloy

C-103 is niobium alloy ine 89% niobium, 10% hafnium uye 1% titanium, iyo inogona kushandiswa mumvura rocket propulsion nozzles, senge injini huru yeApollo lunar module. Iyo Apollo sevhisi module yakashandisa akasiyana sirivheri alloy. Sezvo niobium inotanga kuita oxidize pamusoro pe400 ° C, kuitira kuti irege kuva brittle, chivharo chekudzivirira chinofanira kuiswa pamusoro payo.

Niobium inoitawo basa rakakosha mukuvhiya, haingoshandiswe chete kugadzira michina yekurapa, asiwo yakanaka "biological adaptive material", nekuti ine yakanakisa corrosion resistance, haizodyidzana nezvinhu zvakasiyana-siyana zvemvura mumuviri wemunhu. , uye zvinenge zvachose hazvikuvadzi zvipenyu zvemuviri zvipenyu, nekuti chero nzira dzekubereka dzinogona kuchinjirwa. Saka inogona kusunga kune organic tissue kwenguva yakareba uye inoramba isingakuvadzi mumuviri.
