Kev ceev faj: PVD txheej muaj zog adhesion, tab sis nws yog ib qho nyuaj rau ua tiav cov txheej txheej ntawm ib cheeb tsam loj.CVD yuav ua rau theem transformation ntawm titanium, yog li nws yog tsim nyog los optimize cov txheej txheem tsis.
Summary ntawm cov ntsiab lus tseem ceeb kom nco ntsoov:
1. Hydrogen embrittlement risk: Acid pickling (HF) los yog electroplating txheej txheem yuav ua rau hydrogen embrittlement, yuav tsum tswj cov kua qaub muaj pes tsawg leeg thiab cov txheej txheem tsis.
2. Oxidation tswj: Thaum lub sij hawm hightemperature txheej txheem (xws li thermal oxidation thiab CVD), nws yog tsim nyog los tiv thaiv oxidation ntau dhau los yog theem transformation ntawm titanium.
3. Biocompatibility: Titanium siv nyob rau hauv daim ntawv thov kev kho mob yuav tsum xyuas kom meej nontoxicity ntawm nws nto (xws li, tsis txhob Al₂O₃ sandblasting residues).
4. Hnav / corrosion kuj sib npaug: TiN txheej tuaj yeem txhim kho kev hnav tsis kam thiab corrosion kuj, tab sis tus nqi kuj siab.
5. Kev ruaj ntseg xim: Anodizing xim yuav tsum muaj kev tiv thaiv tom qab.Los ntawm kev xaiv cov thev naus laus zis kho kom zoo, hnav tsis kam, corrosion kuj, lom neeg ua haujlwm, lossis cov khoom zoo nkauj ntawm cov ntaub ntawv titanium tuaj yeem txhim kho tau zoo, ua tau raws li daim ntawv thov xav tau hauv ntau qhov chaw.
