Yuav ua li cas anodize titanium

Taw qhia:

Titanium yog cov hlau ntau yam siv dav hauv ntau qhov kev lag luam vim nws cov khoom zoo xws li lub zog siab, kev tiv thaiv corrosion, thiab lub teeb yuag. Anodizing titanium yog cov txheej txheem uas txhim kho nws cov txheej txheem oxide ntuj, ua rau muaj kev txhim kho ruaj khov, muaj zog tiv thaiv corrosion, thiab muaj peev xwm ntxiv cov xim zoo nkauj. Hauv tsab xov xwm no, peb yuav tshawb xyuas qhov ua tau ntawm anodizing titanium, cov ntaub ntawv xav tau, txheej txheem anodizing, kev txwv, thiab lwm yam.

Puas muaj peev xwm anodize titanium?

Anodizing titanium yog qhov tseeb ua tau thiab siv dav. Cov txheej txheem anodizing suav nrog tsim cov oxide txheej ntawm cov hlau siv cov tshuaj electrolytic.Titaniummuaj cov txheej txheem oxide ruaj khov, tab sis anodizing thickens thiab ntxiv dag zog rau nws, muab cov txiaj ntsig ntxiv.

Dab tsi yog qhov kev daws teeb meem rau anodize titanium?

Txhawm rau anodize titanium, yuav tsum muaj cov tshuaj electrolyte tsim nyog. Feem ntau, kev sib xyaw ntawm sulfuric acid (H2SO4) thiab dej yog siv los ua cov electrolyte. Cov concentration ntawm sulfuric acid, kub, thiab lwm yam additives tuaj yeem hloov kho kom ua tiav cov txiaj ntsig xav tau. Cov tshuaj electrolyte sib txawv kuj tuaj yeem siv rau cov ntawv thov tshwj xeeb, xws li phosphoric acid-raws li kev daws teeb meem rau kev siv biomedical.

Dab tsi cov ntaub ntawv xav tau los anodize titanium?

Titanium qhov chaw: Cov khoom yuav tsum tau anodized yuav tsum tau ua los ntawm ntshiab titanium los yogtitanium alloysnrog zoo anodizing zog.

Electrolyte tov: Ib qho sib xyaw ntawm sulfuric acid thiab dej, nrog ntau qhov sib txawv nyob ntawm qhov xav tau.

Fais fab mov: Ib qho hluav taws xob ncaj qha (DC) yuav tsum muaj rau cov txheej txheem electrolytic. Ib qho rectifier lossis fais fab mov muaj peev xwm xa cov hluav taws xob tswj tau yog feem ntau siv.

Dab tsi yog txheej txheem ntawm anodizing titanium? Cov txheej txheem anodizing muaj ob peb kauj ruam:

Kev npaj nto: ntxuav cov titanium nto los ntawm kev tshem tawm cov av, roj, lossis oxide txheej.

Electrolyte da dej teeb: Raus qhov titanium hauv cov tshuaj electrolyte thiab txuas mus rau qhov zoo davhlau ya nyob twg (anode) ntawm lub hwj chim mov.

Kev teeb tsa Cathode: Txuas cov khoom siv hluav taws xob tsim nyog (xws li txhuas) mus rau qhov tsis zoo (cathode) ntawm cov khoom siv hluav taws xob thiab muab tso rau hauv electrolyte.

Anodizing: Siv cov hluav taws xob tswj hluav taws xob rau hauv Circuit Court, ua rau cov pa oxygen ions tsim thiab hnov ​​​​mob nrog titanium nto, tsim kom muaj txheej tuab oxide.

Xim (yeem): Los ntawm kev tswj hwm yam xws li voltage, lub sij hawm, kub, thiab additives, ntau yam xim yuav ua tau tiav thaum lub sij hawm anodizing txheej txheem.

Sealing: Txhawm rau txhim kho corrosion kuj thiab kav ntev ntawm anodized titanium, nws yog feem ntau kaw siv dej kub, chav, los yog tshuaj sealants.

Vim li cas titanium tsis tuaj yeem ua anodized liab?

Thaum muaj ntau yam xim tuaj yeem ua tiav los ntawm anodizing titanium, ua tiav cov xim liab tiag tiag yog qhov nyuaj. Lub hauv paus yog vim li cas nyob rau hauv lub physics ntawm lub teeb cuam tshuam thiab lub thickness ntawm oxide txheej yuav tsum tau tsim liab wavelengths. Titanium oxide txheej ua pob tshab ntawm thicknesses tsim nyog rau xim liab, ua rau tsis muaj xim saturation. Txawm li cas los xij, cov xim zoo li bronze, ntshav, xiav, thiab ntsuab tseem tuaj yeem tau txais kev ntseeg siab.

titanium puas tuaj yeem hloov dub?

Yog lawm, titanium tuaj yeem ua anodized kom ua tiav cov xim dub. Dub titanium tuaj yeem tau txais los ntawm kev siv qhov sib xyaw ua ke ntawm qhov hluav taws xob, lub sijhawm, thiab electrolyte concentration. Qhov tuab ntawm oxide txheej cuam tshuam rau qhov pom kev pom, thiab txheej tuab dua yuav ua rau cov xim dub tsaus.

Puas yog anodizing ruaj khov?

Anodizing yog kev kho saum npoo uas hloov cov titanium oxide txheej, ua rau nws yog ib feem ntawm cov hlau nto. Nws muab kev txhim kho durability thiab corrosion kuj. Txawm li cas los xij, qhov ntev npaum li cas yog nyob ntawm daim ntawv thov, ib puag ncig yam, thiab kev kho saum npoo tom ntej lossis tuav. Kev saib xyuas kom zoo tuaj yeem pab tswj xyuas qhov anodized tiav rau lub sijhawm ntev.

Xaus:

Anodizing titanium muaj ntau cov txiaj ntsig, suav nrog kev txhim kho corrosion, txhim khu kev ruaj ntseg, thiab muaj peev xwm ntxiv cov xim zoo nkauj. Los ntawm kev nkag siab txog cov txheej txheem, cov kev daws teeb meem electrolyte, thiab cov ntaub ntawv tsim nyog, ib tus tuaj yeem ua tiav anodize titanium rau ntau yam kev siv. Thaum ua tiav cov xim liab tiag tiag yuav nyuaj, lwm cov xim vibrant, suav nrog dub, tuaj yeem tau txais kev ntseeg siab. Anodizing yog cov txheej txheem tseem ceeb uas txhim kho kev ua tau zoo thiab kev zoo nkauj ntawm titanium Cheebtsam.
