Titanium thiab nws cov alloys tau siv dav hauv ntau daim teb vim lawv cov tshuaj muaj zog thiab tshuaj lom neeg. Yog li, ua Titanium thiab nws cov alloys oxidize hauv huab cua? Cov lus teb yog muaj, tab sis cov qib ntawm oxidation yog sib xws hais txog qhov kub thiab txias.
Nyob rau hauv chav tsev kub, titanium yog ruaj khov. Thaum nthuav tawm huab cua, ib qho xim oxide oxide sai sai rau ntawm nws qhov chaw. Daim yeeb yaj kiab no yog kev cog lus thiab ruaj khov, txawm tias tiv taus corrosion los ntawm cov tshuaj uas xeb zoo xws li Aqua Regia. Nws muab kev tiv thaiv zoo heev rau titanium thiab nws cov alloys, ua rau lawv tsis tshua raug rau kev txuas ntxiv oxidation ntawm chav tsev kub.
Txawm li cas los xij, ntawm cov chaw kub, Titanium cov khoom tau pauv tau ntau. Thaum kub siab, titanium dhau los ua neeg nyiam thiab muaj cov khoom siv oxidizing muaj zog, muaj peev xwm tawm ntawm cov oxygen los ntawm oxygen los ntawm oxygen los ntawm oxygen los ntawm oxygen. Hauv lwm lo lus, titanium tus oxidizing cov zog nce nrog kev nce kub. Cov yeeb yaj kiab oxide tsim rau ntawm Titanium nto sib txawv nrog cov oxidation kub, ua rau muaj xim sib txawv ntawm cov oxidized nto.
Raws li qhov tseeb tias titanium nthuav cov xim sib txawv ntawm cov xim sib txawv, feem ntau suav nrog cov xim av, feem ntau suav nrog kev kho mob atmospheration, thiab kev kho tshuaj lom neeg thiab tshuaj lom neeg. Anodic oxidation yog ib txoj kev siv xim ntau. Cov kev sim hauv qab no yog kev nkag siab tob tob txog cov txheej txheem anodizing thiab cov ntsiab cai.
Ua ntej, npaj kev daws teeb meem. Npaj cov sulfuric acid thiab distilled dej nyob rau hauv ib qho kev sib piv ntawm tsawg dua 1:10 kom tau txais kev daws nrog cov roj sulfuric tsawg. Cov kauj ruam no yog qhov tseem ceeb rau cov txheej txheem anodizing, thiab kev daws teeb meem thiab piv ncaj qha cuam tshuam rau cov xim ua kom muaj xim ntxiv.
Ua ntej ua cov ntawv xeem xim tiag tiag, kev sim nrog ib seem titanium phaj. Titanium phaj ua hauj lwm raws li anode, thiab tuab tooj liab hlau ua haujlwm raws li cantre. Muab lawv tso rau hauv npaj electrolyte tov. Tom qab muaj hwj chim rau, npuas yuav raug pom nyob rau hauv electrolyte, qhia cov txheej txheem electrolysis tau pib. Kauj ruam no feem ntau yog rau cov kev paub ua ke nrog cov txheej txheem thiab saib xyuas cov kev cuam tshuam hluav taws xob thawj zaug, npaj rau cov txheej txheem xim ntxiv.
Tom ntej, npaj mus rau cov txheej txheem xim. Tso cov khoom lag luam titanium kom tau xim nyob rau hauv cov npaj aqueous daws thiab teeb lub voltage rau 15v. Lub zog siv hluav taws xob tsis raug txwv tsis pub tsawg thiab tuaj yeem hloov kho raws li cov xim uas muaj xim thiab pom cov txiaj ntsig xim. Thaum lub sij hawm lub zog-ntawm cov txheej txheem, raws li cov tshuaj tiv thaiv taus, cov aqueous daws maj mam hloov, hloov mus rau lub xiav tooj liab sulfate daws. Nyob rau tib lub sijhawm, nws tau pom meej meej tias lub titanium nto tau ua tiav dawb. Qhov no vim tias kev tawm tsam oxidation tshwm sim rau ntawm Titanium nto nyob rau hauv cov txheej txheem no, sib sau ib qho xim oxide nrog cov xim tshwj xeeb, yog li ua tiav cov txiaj ntsig xim.
Hauv cov ntsiab lus, titanium thiab titanium alloys ua oxidize nyob rau huab cua, thiab qib kev hloov pauv ntawm oxidation thiab kev hloov xim muaj feem cuam tshuam txog qhov kub thiab txias. Cov txheej txheem xim xws li anodizing tuaj yeem tiv thaiv cov xim sib txawv rau Titanium thiab titanium alloy khoom, kev sib ntsib muaj ntau yam thov kev siv nyiaj.
Lub tuam txhab khav ua cov khoom lag luam hauv tsev titanium ua ntau lawm, nrog rau:
German-imported precision titanium raj ntau lawm kab (txhua xyoo muaj peev xwm ntau lawm: 30,000 tons);
Japanese-technology technology tentanium ntawv ci rolling kab (thinnest rau 6μm);
Qoos motated titanium qws txuas ntxiv mus rau kab extrusion;
Ntse titanium phaj thiab sawb fining;
MES system ua noj digital tswj thiab kev tswj hwm ntawm tag nrho cov txheej txheem ntau lawm, ua tiav cov khoom lag luam seem ntawm ± 0.01M.
