Vim li cas thiaj xaiv Titanium Alloy Anodizing?

Titanium alloy anodizing treatment generates a dense oxide film on the substrate surface through electrochemical reaction. Nws tuaj yeem tsis tsuas yog ua kom muaj qhov tsis xws luag ntawm cov khoom siv tab sis kuj tseem ua rau nws muaj ntau yam kev ua haujlwm zoo, dhau los ua cov thev naus laus zis tseem ceeb los txhim kho kev ua tiav ntawmtitanium alloy.

 

(1) High Controllability ntawm txheej txheej thiab muaj pes tsawg leeg

Titanium alloy anodizing tsim cov oxide zaj duab xis feem ntau yog tsim los ntawm titanium dioxide ntawm titanium nto hauv ib qho electrolyte nyob rau hauv daim ntawv thov hluav taws xob. Nws muaj ib daim ntawv cog lus metallurgical nrog lub substrate, uas muaj kev sib txuas lus muaj zog thiab tsis kam rau tev, uas zoo tshaj rau cov txheej txheem xws li electroplating thiab txau. Cov txheej txheem txheej txheem tuaj yeem tswj hwm los ntawm electrolyte, voltage, kub, thiab sijhawm. Cov zaj duab xis ntxeem tau yog tsim nyob rau hauv ib tug acidic system, thaum ib tug ntom zaj duab xis yog tsim nyob rau hauv ib tug alkaline system (NaOH), nrog thickness ntawm 0.5μm, 1.5μm, thiab 5μm.

 

Cov txheej txheej loj hlob dhau peb theem: lub sijhawm tsim, lub sijhawm thickening, thiab lub sijhawm ruaj khov. Thaum pib, txheej txheej tuab ntawm 1-5nm yog tsim, ua raws li kev loj hlob ntawm ib txheej ntxeem tau ntawm sab nrauv, thiab thaum kawg nkag mus rau lub sijhawm ruaj khov tom qab qhov sib npaug ntawm kev loj hlob thiab kev sib cais tiav. Kho cov txheej txheem tsis tuaj yeem hloov cov txheej thickness, pore qauv, roughness, thiab hydrophilicity / hydrophobicity.

 

(2) Qhov tseem ceeb Synergistic Optimization ntawm kev ua tau zoo

Tom qab anodizing, txheej txheej txheej ntawm titanium alloy tuaj yeem txhim kho corrosion kuj, hardness, thiab hnav tsis kam. Nws muaj cov tshuaj lom neeg ruaj khov zoo heev, nrog tus nqi corrosion tsawg dua lossis sib npaug ntawm 0.001 hli / xyoo hauv 3.5% NaCl tov, uas yog qhov zoo tshaj plaws rau liab qab titanium thiab tuaj yeem tiv taus yaig los ntawm cov kua qaub muaj zog, muaj zog alkalis, marine ntsev tsuag, thiab lwm yam. Lub hardness ntawm 300-800HV, uas tuaj yeem txhim kho qhov hnav tsis kam.

 

Tsis tas li ntawd, cov txheej txheej muaj kev ua haujlwm zoo rwb thaiv tsev, thiab cov txheej oxide tuab tuaj yeem thaiv cov electron txaus kom ua tau raws li cov txheej txheem rwb thaiv tsev ntawm cov khoom siv hluav taws xob. Conductivity kuj tuaj yeem tswj hwm los ntawm cov txheej txheem optimization, nrog lub ntim resistivity tsawg dua los yog sib npaug rau 10⁴Ω・cm, yoog raws li cov kev xav tau ntawm cov txheej txheem txheej txheej.

 

(3) Kev sib xyaw ua ke ntawm kev kho kom zoo nkauj thiab kev ua haujlwm

Titanium alloy anodized zaj duab xis muaj qhov tshwj xeeb kho qhov muag. Los ntawm kev tswj qhov voltage thiab zaj duab xis thickness, uniform, ruaj khov, thiab nplua nuj xim xws li golden daj, xiav, ntshav, thiab dub tuaj yeem ua tiav los ntawm kev cuam tshuam lub teeb yam tsis tas yuav dyeing. Nws cov yam ntxwv ntawm kev sib koom ua ke kho kom zoo nkauj thiab kev tiv thaiv ua rau nws muaj txiaj ntsig zoo hauv kev kho kom zoo nkauj thiab cov hniav nyiaj hniav kub. Tom qab kev txhim kho cov txheej txheem, cov txheej txheem kuj tuaj yeem tau txais txiaj ntsig nrog cov haujlwm tshwj xeeb xws li kev kho mob - qib biocompatibility thiab tiv thaiv - fouling khoom rau marine engineering.

(1) Lub Rooj Sib Tham Sib Tham Sib Tham Yuav Tsum Muaj

Cov txheej txheem no muaj qhov hloov pauv tau yooj yim thiab tuaj yeem hloov kho raws li qhov sib txawv ntawm daim ntawv thov los ntawm electrolyte thiab parameter regulation:

 

Nyob rau hauv aerospace teb, sulfuric acid system los yog pulse anodization txheej txheem yog siv los kho cov Cheebtsam xws li Gr5 titanium bolts, npaj hnav- tiv taus coatings kom muaj kev nyab xeeb davhlau thaum ua tau raws li qhov hnyav txo thiab tiv thaiv -corrosion yuav tsum tau ntawm aircraft Cheebtsam;

 

Hauv kev kho mob, oxalic acid system yog siv los npaj cov txheej txheem biocompatible rau cov pob qij txha, kev cog hniav, thiab lwm yam;

 

Hauv kev siv hluav taws xob, phosphoric acid-raws li electrolyte yog siv kom tau cov txheej txheem ua tau zoo, ua kom yooj yim rau cov khoom siv me me thiab kev ua haujlwm siab. Tsis tas li ntawd, cov txheej txheem muaj ntau yam kev hloov pauv, muaj feem xyuam rau cov ntshiab titanium thiab titanium alloys xws li Gr5.

 

(2) Environmental Friendliness thiab Economy

Piv nrog rau cov txheej txheem ib txwm muaj xws li chromate passivation thiab electroless plating, titanium alloy anodizing yog ib puag ncig zoo.
