titanium anodising
Cov kauj ruam ntawm titanium anodising txheej txheem
Titanium anodising yog ua tib zoo ua raws li cov txheej txheem Thaum ntawm nws cov tub ntxhais nws yog cov tshuaj tiv thaiv electrochemical, qhov kev vam meej ntawm qhov tshwm sim yog nyob ntawm qhov ua tau zoo ntawm txhua kauj ruam! Cia peb saib ze dua ntawm txhua theem ntawm txheej txheem titanium anodising.
Kauj Ruam 1: Ntxuav thiab kho ua ntej
Ua ntej anodising, nws yog ib qho tseem ceeb los xyuas kom meej tias titanium nto tsis muaj kab mob, roj los yog tej txheej oxidation yav dhau los.
- Degreasing:Ua ntej, daim ntawv titanium yog raus rau hauv cov tshuaj degreasing kom tshem tawm cov organic residues lossis roj. Feem ntau siv cov kuab tshuaj muaj xws li acetone lossis isopropyl cawv.
- Yaug:Tom qab degreasing, daim yog rinsed kom huv si nrog distilled los yog deionised dej kom tshem tawm cov hnyav residues.
- Acid ntxuav: Titanium yog tom qab ntawd raus hauv cov tshuaj acid (feem ntau sib tov ntawm nitric thiab hydotes ua paug rau cov khoom noj oxide zoo dua tshiab ntawm cov roj oxide tshiab
Kauj Ruam 2: Kev Npaj Electrolyte
Cov tshuaj electrolyte (feem ntau yog dilute sulfuric acid) yog qhov nruab nrab los pab txhawb cov dej ntws ntawm cov dej ntws thaum lub sij hawm anodising txheej txheem. Nws cov concentration thiab pH yuav tsum tau ua kom zoo kom tau txais txiaj ntsig zoo ib yam.
Cov kua qaub yog tov nrog dej distilled nyob rau hauv qhov proportions kom ntseeg tau tias ib tug uniform concentration. Tom qab ntawd, qhov ntsuas kub ntawm cov electrolyte raug saib xyuas thiab tswj. Qhov kub qis dua tuaj yeem ua rau oxide txheej tawv!
Kauj Ruam 3: Anodizing
Qhov no yog lub hauv paus theem uas cov khawv koob ntawm cov xim thiab kev tiv thaiv tshwm sim. Daim ntawv titanium txuas nrog lub davhlau ya nyob twg zoo (anode) ntawm lub zog hluav taws xob, thaum lub cathode (feem ntau yog ua los ntawm cov hlau lead lossis stainless hlau) txuas nrog lub davhlau ya nyob twg tsis zoo. Ob lub anode (titanium) thiab cathode yog raus rau hauv cov tshuaj electrolyte kom ntseeg tau tias lawv tsis tuaj yeem sib cuag.
Siv ncaj qha tam sim no Raws li qhov voltage nce, oxygen ions hauv electrolyte tsim ib txheej oxide ntawm titanium nto Lub thickness ntawm cov oxide txheej thiab cov xim tshwm sim ncaj qha cuam tshuam rau qhov siv hluav taws xob.
Kauj Ruam 4: Yaug tom qab anodising
Thaum qhov xav tau oxide thickness (thiab xim) tau tiav, daim ntawv titanium raug tshem tawm ntawm electrolyte thiab yaug. Tam sim ntawd yaug nrog dej distilled los yog deionised kom nres cov txheej txheem anodising thiab tshem tawm cov acid residue.
Kauj Ruam 5: Sealing (yeem)
Sealing txheej anodised yog ib qho kev xaiv uas yuav tsum tau rau qee qhov kev siv los txhim kho corrosion kujHydration sealingNws suav nrog boiling los yog steaming lub workpiece los hloov cov titanium oxide mus rau hydrated titanium oxide, zoo sealing qhov pores. Lwm txoj kev yogtxias sealing, qhov twg ib feem yog immersed nyob rau hauv ib tug nickel acetate tov ntawm ib tug qis kub.
Kauj Ruam 6: Kev Tshuaj Xyuas Zoo
Lub anodised titanium oxide tau dhau los ntawm ntau qhov kev ntsuam xyuas kom ntseeg tau tias nws ua tau raws li qhov yuav tsum tau ua. Piv txwv li, lub thickness ntawm cov oxide txheej yog ntsuas los ntawm cov khoom siv xws li ib tug eddy tam sim no meter, thiab cov xim uniformity thiab zoo li yog visually soj ntsuam xyuas tej inconsistencies los yog tsis xws luag.
