3D Printing Niobium(Nb)Metal Powder for Metallurgical Purposes
Mafotokozedwe Akatundu
Mankhwala a niobium ufa makamaka ndi niobium oxide, kawirikawiri niobium pentoxide.Njira zake zazikulu zopangira ndi njira yochepetsera mankhwala, njira yochepetsera ma electrolytic ndi njira yopera yamakina.Pakati pawo, njira yochepetsera mankhwala ndi njira yochepetsera electrolytic ndiyo njira zazikulu zopangira mafakitale akuluakulu a niobium ufa, pamene njira yopera yopangira makina ndi yoyenera kwa ang'onoang'ono kapena ma laboratory kukonzekera kwa ufa wochepa wa niobium ufa.Niobium ufa uli ndi ntchito zosiyanasiyana m'madera ambiri, monga ng'anjo yotentha kwambiri, kupanga zipangizo zamagetsi, ndege, zitsulo, biomedicine, ndi zina zotero.

mapulogalamu
1. Niobium ndi chinthu chofunika kwambiri cha superconducting kuti apange capacitor yapamwamba kwambiri.
2. Niobium ufa amagwiritsidwanso ntchito kupanga tantalum.
3. Niobium metal powder wangwiro kapena Niobium Nickel alloy amagwiritsidwa ntchito popanga Nickel, Chrome ndi Iron base high heat alloy.
4. Kuwonjezera 0.001% mpaka 0.1% Niobium ufa kuti asinthe makina azitsulo 5. Amagwiritsidwa ntchito ngati zinthu zosindikizidwa za chubu cha arc.

Huarui ali ndi dongosolo lokhazikika loyang'anira.Timayesa zinthu zathu poyamba tikamaliza kupanga, ndipo timayesanso tisanaperekedwe, ngakhale zitsanzo.Ndipo ngati mukufuna, tikufuna kuvomereza gulu lachitatu kuti tiyese.Zachidziwikire ngati mukufuna, titha kukupatsani zitsanzo kuti muyese.
Zogulitsa zathu zimatsimikiziridwa ndi Sichuan Metallurgical Institute ndi Guangzhou Institute of Metal Research.Kugwirizana kwanthawi yayitali ndi iwo kumatha kupulumutsa nthawi yambiri yoyesera kwa makasitomala.
