Ii. Tub Ntxhais Manufacturing
1. High-Purity Melting Tshuab
Lub tshuab nqus tsev muaj cov arc melting (var): peb-lub sij hawm recelting txheej txheem, tswj hwm tag nrho cov nyiaj uas impurity<500ppm.
Hauv hluav taws xob nqaj txias txaj melting (Ebchm): Zoo tshem tawm cov pej xeem siab (HDI<1/cm3).
Ntshav arc melting (PAM): Ua tiav 99.999% lub tshuab nqus tsev kom ntseeg tau cov khoom siv huv.
2. Kub Ua Haujlwm Tswj System
Theem txheej txheem tsis ua haujlwm zoo yuav tsum tau forging thiab daim pam bit thaj chaw (980 ±
Kub Rolling sib sau ua ob-theem ntsuas kub (750-850 degree) depition) diam txwv ± {2}}. 5 hli.
Precision forging and shaping Isothermal forging near B phase area Streamline continuity >95%.
3. Microstructure kev tswj
Kev Kho Mob: Dej ceev ceev quenching hauv b theem (txias tus nqi> 50 degree / s).
Kev Zov Kev Loj Hlob: {{480-550 degree rau 8 teev rau precipitly nanoscale ib ntu (loj {2}} nm).
Ob chav Annealing: B Annealing + A + B Annealing kom tau txais dual-lub xeev qauv.
III. Cov thev naus laus zis tseem ceeb
1. Ultra-Precision Moulding
Ntau ntau-axis CNC tig: PCD tuam degree, nto roughness ra {}}. {3}}.<50um
2. Nto Kev Kho Mob
Txheej Txheem Kev Ntsuas Cov Qauv Ua Haujlwm
Electrolytic polishing Voltage 12V, temperature -30℃ Surface roughness Ra0.05um Micro-arc oxidation Pulse frequency 1000Hz Generate 50um porous TiO₂ layer HA coating Plasma spraying Bonding strength>35MPA
IV. Cov Txheej Txheem Puv-Txheej Txheem Tswjhwm
1. Txheej Txheem Nrhiav tau Technology
Online Thermal Kev Ntsuas: Kev tshuaj xyuas lub sijhawm tiag tiag ntawm kev ua cov kub hloov pauv (± 3 degree)
EBSD analysis: grain orientation difference >15 Qib Demree Piv Txwv<5%
X-ray residual stress detection: surface compressive stress >200MPA
2.terminal kev soj ntsuam cov qauv
Cov khoom kuaj, cov hau kev, cov qauv tsim nyog
Qaug zog, peb-taw tes khoov, tsis muaj fracture tom qab 107 mus
Biocompatibility, cytotoxicity test, survival rate>90%
Corrosion resistance, potentiodynamic polarization test, pitting potential>1.2V
Tshuab Kev Loj Hlob
1. Ntxiv kev tsim kho kev kho mob Titanium alloy hmoov nrog ib qho loj me ntawm {{1 um)
2. Txawj Ntse Ntau Lawm: Tsim ib qho kev ua kom tiav cov txheej txheem kom ua tiav cov txheej txheem ntsuas hluav taws xob
3. Nto Right Functanization: Tsim cov txheej txheem tshuaj tua kab mob (EG + tshuaj thauj khoom {}}}} ug / cm2)
Kev tsim kho mob titanium alloy cov tuav sib xyaw ua ke ntau yam thev naus laus zis xws li cov khoom siv science, precision machining thiab biomedicine. Nws cov txheej txheem tswj xyuas qhov nce mus txog qhov micron qib, thiab cov khoom tsim nyog tus nqi yuav tsum lees tias yuav tsum tau ua siab tshaj 99.99%. Nrog rau kev txhim kho ntawm 3D luam tawm kev kho thev naus laus zis, kev cog lus kev kho mob yuav ua rau muaj kev coj ua ntawm tus kheej thiab ua haujlwm yav tom ntej
