1.What yog tus tseem ceeb ua neeg ua hauj lwm cov cai ntawm hluav taws xob teb pab tau?
Cathohode Polarization Ehirances
Ion Kev tsiv teb tsaws chaw:
Sab Nraud Hluav Taws Xob (feem ntau DC 3-5v / cm / cm) drives zn²⁺ rau migrate mus rau lub Cathode nto nyob rau hauv ib qho kev coj ua, txo qhov kev xav polarization
→ Depositition tus nqi nce ntxiv los ntawm 20-30% (ntawm tib lub ntom ntom tam sim no) • Nucleation Barrier txo:
Fais Teb nce cathode overpotential los ntawm 50-100mv, txhawb kev tsis pub muaj nucleation instantant (tsis muaj kev xaiv nucleation)
Crystal lub dav hlau nyiam cov kev tswj hwm orientient
Fais fab teb tsim zn²⁺ rau dlhos perpendicular mus rau matrix raws c-axis, vim tias cov hluav taws xob qis, thiab hluav taws xob teb yooj yim drive ion embedding yooj yim tsav ion
2.Qhov dab tsi hloov cov qauv crystal ntawm zinc txheej?
Lis cov ua kom zoo thiab homogenization
Cause: Fais teb nce ua nucleation tus nqi (tus naj npawb ntawm nuclei rau ib cheeb tsam ↑ 3-5 zaug); inhibits Cibrar Crystal kev loj hlob thiab txhawb nqa equiaxed crystal tsim.
Txo cov khoom siv crystal
Kev Tiv Thaiv Kev Nyab Xeeb Quav: Txo los ntawm 10¹⁰ CM⁻² (PACTIONAL) txog 10⁸-10⁹ CM⁻² (FOOP TEB SANMENTED)
Twin ciam duab piv: Txo los ntawm 12-15% rau<5% (due to electric field suppression of non-uniform nucleation)
3.Qhov kev cai twg ntawm kev cuam tshuam ntawm hluav taws xob teb tsis ntawm daim ntaub?
Tam sim no ceev txuas ntxiv cov nyhuv
Qhov tseem ceeb ua kom zoo thaj chaw:
Fais Teb: 3-5 V / Cm
Qhov ceev tam sim no: 15-25 A / dm² → Txog ntawm no, tus nqi tso nyiaj thiab cov ntaub ntawv ua kom zoo nkauj mus txog qhov sib npaug.
Kev Nyuaj Siab Tshaj: Thaum ceev tam sim no yog ntau dua 30 A / DM², Pores tseem yog tsim txawm tias thaum hluav taws xob tau thov.
4.What yog cov kev sib tw ntawm kev siv khoom lag luam yog dab tsi?
Ntug Khoom Siv Tswjhwm
Qhov Teeb Meem: Hluav taws xob teb yog muaj ntau lub ntsej muag ntawm lub workpiece, uas ua rau muaj ntau dhau tuab zinc txheej
Kev Lag Luam Zog Kev Lag Luam
Kev siv zog tau sib piv:
Pa Galvanizing: 0.3-0.5 kWh / m²
Field teb tau pab: 0.5-0.8 kWh / m²
Kev sib xyaw ntawm cov khoom loj
Segmented Fais Teb Technology:
Faib cov workpiece rau hauv cov ntu thiab thov cov hluav taws xob sib txawv
5. Peb qhov kev hloov pauv tau ua tiav los ntawm cov hluav taws xob teb pab cuam tshuam zinc plating los ntawm kev coj ua tshwj xeeb ntawm Zinc ion Kev Cwj Pwm Deposition?
Crystallographic optimization: strong (002) texture (>70%) + daim nplaum ua kom zoo rau 3-8μm.
Kev phiv Engineering: Dislandsiav / cov ntxaib ntom ntom txo los ntawm 1-2 xaj ntawm qhov ntau.
Interface ntxiv dag zog zog ntxiv: Fe-Zn Alloy Txheej Technined los ntawm 50% thiab pluav.
