Raw Khoom Npaj
Electron nqaj melting (EBM): Melting nyob rau hauv 10⁻⁴ lub nqus tsev los tshem tawm cov pa thiab nitrogen impurities rau<50 ppm.
Thaj chaw melting (ZM): Purification los ntawm kev tsiv cov lus cua sov, lub impurity cov ntsiab lus yog txo rau<1 ppm.
Ua txheej txheem
Forging: Kub 1100-1250 degree, deformation<30%, avoid grain coarsening.
Extrusion: Siv cov iav roj nplua nyeem, qhov Extrusion Piv tawm mus txog 50: 1, thiab {2}} hli cov pas nrig tau tsim tawm.
Nto Kho
Anodizing: Tsim 5-20} μide zaj duab xis los txhim kho corrosion tsis kam thiab bioactivity.
Lub cev vapor deposition (PVD): Tin Txheej, Hardness, hardness nce mus rau 2000 hv, coj tus nqi tiv thaiv ntau zuj zus los ntawm 10 zaug.
