3D Printing Niobium(Nb)Metal Powder for Metallurgical Purposes
Mafotokozedwe Akatundu
Niobium chitsulo ufa, malo osungunuka 2468 ℃, malo otentha 4742 ℃, osalimba 8.57g/cm3.Amagwiritsidwa ntchito kwambiri muzitsulo zosapanga dzimbiri, maginito a superconducting, zitsulo za ufa, zida zowotcherera ndi zina.Niobium chitsulo ufa uli ndi mitundu iwiri, yozungulira komanso yosazungulira.3D yosindikiza, laser cladding, kupopera mbewu mankhwalawa plasma ndi zina.

Mtengo wa SEM
Kugwiritsa ntchito
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.
Njira yoyendetsera bwino
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.
