Titanium thiab nws cov alloys pom dav siv nyob rau hauv ntau yam kev lag luam sectors vim lawv tshwj xeeb lub cev thiab tshuaj zog. Ntawm cov txheej txheem kho saum npoo rau titanium thiab nws cov alloys, cov txheej txheem anodizing thiab xim tau txais kev saib xyuas zoo rau lawv cov txheej txheem yooj yim, kev xaiv xim nplua nuj, thiab kev siv nyiaj. Hauv tsab xov xwm no, peb yuav muab cov ncauj lus ntxaws ntxaws ntawm cov txheej txheem anodizing thiab xim rau titanium thiab nws cov alloys, nrog rau lawv cov ntawv thov kev lag luam thiab kev cia siab.
Anodizing txheej txheem rau Titanium thiab nws cov Alloys
01
Degreasing
Thawj kauj ruam yog siv cov alkaline-raws li degreasing cov neeg ua haujlwm kom tshem tawm cov roj seem ntawm cov titanium thiab nws cov alloys. Cov kauj ruam no yog qhov tseem ceeb vim tias cov roj residues tuaj yeem cuam tshuam cov kua qaub tom qab thiab cov txheej txheem anodizing, uas yuav ua rau cov xim tsis sib xws.
02
Primary Acid Etching
Tom qab degreasing, cov ntaub ntawv tau txais thawj acid etching. Lub 5% hnyav concentration daws ntawm hydrofluoric acid yog ua hauj lwm rau etch titanium thiab nws cov alloys, pab nyob rau hauv lub tsim ntawm ib tug tshwj xeeb pearlescent qauv ntawm qhov chaw.
03
Secondary Acid Etching
Txhawm rau tshem tawm cov hmoov seem uas tau tsim thaum lub sij hawm thawj cov kua qaub etching, ib theem nrab acid etching yog ua. Kev sib xyaw ntawm hydrofluoric acid thiab hydrogen peroxide tov yog siv los tsim cov khoom sib txuas ruaj khov nrog titanium ions, ua rau lub ntsej muag huv.
04
Anodization
Lub pre-kho titanium thiab nws cov hlau phaj ua hauj lwm raws li anodes, thaum txhuas daim hlau ua raws li cathodes, immersed nyob rau hauv ib tug 1% hnyav concentration phosphoric acid electrolyte rau tas li voltage kho. Raws li qhov voltage nce, cov oxide zaj duab xis ntawm titanium nto maj mam thickens, nthuav tawm ntau yam xim zoo nkauj.
05
Kev sib khi
Txhawm rau txhim kho qhov kev tiv thaiv corrosion, kev tiv thaiv kab mob, thiab hnav tsis kam ntawm cov yeeb yaj kiab anodized oxide, kev kho sealing yog ua. Cov txheej txheem sealing feem ntau suav nrog kev sib khi dej kub, chav sealing, thiab kev daws teeb meem nrog cov ntsev inorganic lossis organic compounds.
06
Qhuav
Tom qab lub sealing txheej txheem, cov av noo noo yog wiped tawm siv ib tug huv si paj rwb ntaub, cia lub workpiece rau cua qhuav lawm.
Cov ntawv thov kev lag luam thiab kev cia siab
Cov txheej txheem anodizing thiab xim rau titanium thiab nws cov alloys tuav lub peev xwm loj heev rau kev lag luam. Ua ntej, cov txheej txheem yog yooj yim thiab raug nqi, ua rau nws haum rau loj-scale industrial ntau lawm. Qhov thib ob, cov xim xim ntawm cov titanium anodized thiab nws cov alloys muaj ntau yam xim zoo nkauj, ua tiav cov kev xav zoo nkauj hauv ntau yam. Tsis tas li ntawd, cov yeeb yaj kiab anodized oxide nthuav tawm zoo heev tiv thaiv corrosion, tiv thaiv kab mob, thiab hnav tsis kam, yog li txhim kho lub neej kev pab cuam thiab ruaj khov ntawm titanium thiab nws cov alloys.
Hauv cov khoom lag luam xws li aerospace, cov cuab yeej kho mob, thiab kho vaj tsev kho kom zoo nkauj, cov txheej txheem anodizing thiab xim rau titanium thiab nws cov alloys pom kev siv dav. Hauv kev lag luam aerospace, nws tuaj yeem ua haujlwm hauv kev tsim cov khoom siv dav hlau thiab cov cav cav. Hauv cov cuab yeej siv kho mob, nws tuaj yeem siv rau cov cuab yeej phais thiab kev cog qoob loo. Hauv kev kho vaj tsev kho kom zoo nkauj, nws tuaj yeem siv rau kev kho saum npoo ntawm lub qhov rooj, qhov rais, thiab kab hlau rhuav phab ntsa.
