Hom I: Xim Anodizing
Titanium yog ib tug tswv cuab ntawm pawg ntawm cov hlau cov ntsiab lus (suav nrog niobium thiab tantiving, nws tuaj yeem ua rau muaj hluav taws xob lossis hluav taws xob kom tsim cov roj nyias nyias saum npoo. Cov oxide no siv rau nws cov xim vim yog qhov tshwm sim ntawm kev cuam tshuam loj. Qhov no yog cov txheej pob tshab heev, thiab thaum lub teeb dawb yog xav txog ntawm lub hauv paus hlau, nws "xim" yog "cuam tshuam" hauv Oxide Txheej. Lub teeb vuag ntawm qee zaus khiav tawm thiab kev ua haujlwm nrog lub teeb sab npoo, txhim kho lossis muab tshem tawm cov xim uas peb pom. Raws li cov tuab tuab ntawm Oxide Txheej nce, lub teeb vuag ntawm ntau zaus khiav dim, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau muaj xim sib txawv, ua rau cov xim sib txawv. Cov xim tshwm sim tshwm sim hauv kev sib tw ua ntu zus mus txog tsib xim rov qab ib zaug ntxiv. Tsis yog tagnrho cov xim nyob rau hauv lub spectrum tuaj yeem tsim tawm. "Liab liab" thiab "Hav zoov ntsuab" tsis tuaj yeem tsim tawm. Cov xim anondized txheej yog qhov tsis tshua muaj nyias (li 50 txog 200 nm). Txawm hais tias nws nyuaj dua li titanium qhov chaw lawv tus kheej, nws tsis tuaj yeem qhia cov coj tau zoo heev vim tias cov yeeb yaj kiab oxide yog li nyias. Cov xim raug tswj tau los ntawm kev thov voltage rau cov tivthaiv los ntawm cov electrolyzer. Muaj ntau cov electrolytes tuaj yeem siv los tsim cov nqaij nyuj. Cov khoom tiv thaiv ua raws li qhov zoo electrode (anode) hauv electrolyte, thaum lub ntsiab lus tsis zoo electrode (catrode) kawg yog txuas nrog DC cov khoom siv fais fab. Ib tug xov tooj ntawm cov txheej txheem tuaj yeem siv rau "xaiv" anodize rau saum npoo. Hauv kev lag luam ntaus ntawv, xim anodeming feem ntau yog siv rau cov khoom lag luam zoo nkauj thiab / lossis kev txheeb xyuas. Piv txwv li, cov neeg ua haujlwm kho mob hauv chav ua haujlwm yuav xav tau kev pab ntawm Magenta, xiav, xim ntsuab, ntsuab thiab tooj daj thiab tawv nqaij ntawm tib lub cheeb thiab qhov ntev sib txawv. Nws yog ib qho tseem ceeb kom paub tias cov xim ntawm cov hlau nws tus kheej tsis tau hloov pauv - tsis zoo li hauv anodizing txhuas, tsis muaj qhov ua kom muaj kev zas lossis pigments tam sim no. Hloov chaw, qhov no nyias txheej ntawm pob tshab oxide ua rau "kev cuam tshuam" ". Anodized titanium cog yog ob qho tib si biocompible thiab hypoallergenic vim tias lawv muaj kev ywj pheej ntawm cov dyes thiab pigments. Muaj ntau txoj kev ntawm anodizing thiab xim titanium thiab titanium alloys. Cov ntsiab lus tseem ceeb cuam tshuam rau cov yeeb yaj kiab oxide yog electrolyte thiab electrolytic voltage. Ob yam no tau raug cais tawm ntawm cov tub ntxhais coob coob. Raws li hom electrolyte siv, nws tuaj yeem faib ua cov kua qaub acc acidic, alkaline tov, cov tshuaj ntsev thiab tov sib xyaw. Raws li lub zog muab siv, nws tuaj yeem faib ua DC Oxidation txoj kev, AC oxidation txoj kev thiab mem tes oxidation txoj kev.
Hom II: Micro Arc Oxidation
Cov Axro-Arc, tseem hu ua Plasma Micro-Arc oxidation, yog cov thev naus laus zis tshiab rau saum npoo hlau uas tsis yog al, mg thiab ti. Cov thev naus laus zis xa mus ncaj qha rau cov neeg hlau matrix mus rau hauv cov oxide ceramics los ntawm sintering ntawm qhov kub thiab siab nyob rau hauv micro-arc slc paug cheeb tsam. Nws muaj cov yam ntxwv ntawm kev ua haujlwm siab, cov txheej txheem yooj yim thiab muaj peev xwm npaj cov yeeb yaj kiab uas muaj zog thiab tuaj yeem npaj cov xim tuab nrog cov ntaub ntawv thoob plaws lub ntiaj teb. Cov thev naus laus zis micro-arc no muaj cov txiaj ntsig hauv qab no: Lub Ceramic Zaj Duab Xis yog zus nyob rau hauv situ, yog li nws txoj kev daws teeb meem yog qhov siab; Qhov muaj pes tsawg leeg thiab cov khoom ntawm zaj yeeb yaj kiab tau hloov pauv los ntawm kev kho cov txheej txheem ntawm electrolyte composition, thiab kev ua haujlwm tsim ntawm zaj duab xis tau txhim kho kom zoo. Cov kev ua tau zoo ntawm matrix yuav tsis ua rau tsis zoo thaum qhov kev tawm kom txaus kub instantaneous kub yog qhov siab. Txawm tias cov duab ntawm cov workpiece tuaj yeem tsim nyob rau sab hauv thiab sab nraud; Kev ua haujlwm yooj yim, ua tau zoo, tsawg dua cov txheej txheem kev kho mob ua ntej, tsis tas yuav muaj kev kub siab lossis lub tshuab nqus tsev; Ua ke nrog qhov zoo ntawm cov khoom sib xyaw ua ke ceramic thiab cov ntaub ntawv hlau, cov khoom lag luam xeb thiab hnav tsis kam ntawm cov khoom hlau yog hloov kho. Qhov saum npoo ntawm titanium alloy thiab ntshiab titanium cov khoom raug rau cov cua lossis cov duab yeeb yaj kiab tuaj yeem tsim cov yeeb yaj kiab oxide, uas tuaj yeem ua kom tuab ntawm cov khoom siv oxidic. Kho cov voltage ntawm anodic oxidation cov txheej txheem kho deg tau tuaj yeem tswj cov xim oxness, thiab ntau cov xim sib txawv yog txiav txim los ntawm cov xim yeeb yaj kiab. Nws tuaj yeem pom los ntawm cov ntaub ntawv tshawb fawb tias tsis muaj xim lossis cov organic zas xim hauv oxide zaj duab xis tsim los ntawm anodic oxidation txheej txheem.
