Txheej txheem thiab kev cia siab ntawm anodic oxidation coloring technology ntawm titanium alloy

Titanium thiab nws cov alloys muaj ntau yam kev siv hauv kev lag luam vim lawv lub cev zoo thiab tshuaj lom neeg. Ntawm lawv, anodic oxidation coloring thev naus laus zis, raws li ib txoj hauv kev kho saum npoo ntawm titanium thiab nws cov alloys, tau nyiam ntau xim vim nws cov txheej txheem yooj yim, nplua nuj xim thiab tus nqi qis. Cov txheej txheem anodic oxidation xim ntawm titanium thiab nws cov alloys thiab nws cov ntawv thov kev lag luam yuav raug qhia kom ntxaws hauv qab no.
I. Anodic oxidation xim txheej txheem ntawm titanium thiab nws cov alloys
Degreasing: Ua ntej ntawm tag nrho cov, nws yog ib qho tsim nyog yuav tsum tau siv cov alkali degreasing tus neeg sawv cev kom tshem tawm cov roj rolling residue rau saum npoo ntawm titanium thiab nws cov alloys. Cov kauj ruam no yog qhov tseem ceeb, vim tias cov roj yuav cuam tshuam rau cov nyhuv tom qab pickling thiab anodizing cov kauj ruam, uas yuav ua rau cov xim tsis sib xws.
Initial Pickling: Tom qab cov txheej txheem degreasing, pib pickling yog ua. Acid pickling ntawm titanium thiab nws cov alloys siv aqueous tov ntawm hydrofluoric acid ntawm ib tug concentration ntawm 5% los ntawm qhov hnyav pab tsim ib tug txawv pear daim tawv nqaij qauv ntawm nws nto.
Secondary Pickling: Yuav kom tshem tawm cov hmoov av tsim nyob rau saum npoo thaum lub sij hawm thawj txheej txheem pickling, theem nrab pickling yog yuav tsum tau. Kev sib xyaw ntawm hydrofluoric acid thiab aqueous hydrogen peroxide yog siv los ntxuav qhov chaw los ntawm kev ua kom ruaj khov ntawm titanium ions.
Anodic oxidation: Pre-kho titanium thiab nws cov phaj hlau yog siv los ua anode thiab txhuas daim hlau ua cathode thiab muab tso rau hauv 1% qhov hnyav ntawm phosphoric acid electrolyte rau kev kho hluav taws xob tas li. Raws li qhov voltage nce, oxide zaj duab xis nyob rau saum npoo ntawm titanium maj mam thickens, qhia cov xim hloov xim.

Kaw: Yuav kom txhim kho corrosion kuj, muaj kuab paug kuj thiab abrasion tsis kam ntawm anodic oxide zaj duab xis, yuav tsum tau kaw kev kho mob. Cov txheej txheem kaw feem ntau suav nrog kev kaw dej kub, chav kaw thiab cov tshuaj kaw uas muaj cov ntsev inorganic thiab cov tshuaj organic.
Qhuav: Tom qab kev kho sealing tiav, siv cov ntaub so ntswg huv los so cov dej noo ntawm qhov chaw ua haujlwm thiab cia nws qhuav lawm.
Thib ob, kev cia siab rau kev siv tshuab
Lub anodic oxidation coloring technology ntawm titanium thiab nws cov alloys muaj ntau yam ntawm daim ntawv thov kev cia siab. Ua ntej tshaj plaws, thev naus laus zis yog qhov yooj yim, tus nqi qis thiab tsim nyog rau kev lag luam loj loj. Qhov thib ob, cov xim ntawm titanium thiab nws cov alloys tom qab xim yog nplua nuj xim thiab muaj cov khoom zoo nkauj zoo nkauj, uas tuaj yeem ua tau raws li qhov xav tau ntawm kev zoo nkauj hauv ntau qhov chaw. Tsis tas li ntawd, anodic oxidation zaj duab xis muaj kev tiv thaiv corrosion zoo, tiv thaiv kev ua qias tuaj thiab hnav tsis kam, uas tuaj yeem txhim kho kev pabcuam lub neej thiab kev ua haujlwm ruaj khov ntawm titanium thiab nws cov alloys.
Hauv kev lag luam, anodic oxidation coloring thev naus laus zis ntawm titanium thiab nws cov alloys tuaj yeem siv rau ntau qhov chaw xws li aerospace, khoom siv kho mob, kho kom zoo nkauj hauv tsev thiab lwm yam. Piv txwv li, nyob rau hauv aerospace teb, anodic oxidation coloring technology ntawm titanium thiab nws alloys yuav siv tau los tsim aircraft qhov chaw thiab cav qhov chaw, thiab lwm yam .; nyob rau hauv cov khoom siv kho mob, nws tuaj yeem siv los tsim cov cuab yeej phais thiab cog, thiab lwm yam .; nyob rau hauv lub tshav pob ntawm architectural kho kom zoo nkauj, nws tuaj yeem siv los tsim cov qhov rooj, qhov rais, kab hlau rhuav phab ntsa thiab lwm yam kev kho deg ntawm cov khoom siv hauv tsev.
Nyob rau hauv luv luv, anodic oxidation coloring technology ntawm titanium thiab nws alloys muaj dav daim ntawv thov prospects thiab loj ua lag luam muaj peev xwm. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho txuas ntxiv ntawm kev lag luam, nws ntseeg tias cov cuab yeej no yuav siv tau ntau dua thiab txhawb nqa yav tom ntej.
