Yuav ua li cas Alloy muaj pes tsawg leeg cuam tshuam rau cov xim ntawm titanium alloy?

Titanium alloy tau siv dav hauv cov teb kawg xws li aerospace, kho mob, thiab tub rog vim nws cov kws kho mob zoo heev thiab corrosion tsis kam. Tab sis ntxiv rau cov yam ntxwv no, cov xim ntawm titanium alloy kuj yog ib qho uas tau nyiam ntau. Yog li, lub alloy muaj pes tsawg leeg cuam tshuam rau cov xim ntawm titanium alloy?

1. Cov khoom lag luam yooj yim thiab cov xim hloov ntawm titanium alloy

Titanium alloy yog ib qho alloy raws li titanium thiab tsim los ntawm kev ntxiv lwm cov khoom hlau. Cov ntsiab lus sib xws xws li txhuas, molybdenum, hlau, tungsten, thiab lwm yam ntxiv tuaj yeem muab cov khoom sib txawv thiab corrosion tsis kam. Nyob rau tib lub sijhawm, cov txheej txheem alloy no kuj cuam tshuam nrog cov xim ntawm titanium alloy. Thaum cov khoom sib txawv ntawm cov hlau sib xyaw ua ke nrog cov yeeb yaj kiab oxide, ua rau muaj kev hloov pauv ntawm cov xim ntawm titanium alloy.

2. Cov nyhuv ntawm oxide zaj duab xis ntawm cov xim ntawm titanium alloy

Cov xim ntawm titanium alloy feem ntau yog los ntawm oxide zaj duab xis tsim nyob rau nws sab. Thaum Titanium raug nthuav tawm rau huab cua, nws rov qab nrog oxygen los ua ib txheej nyias ntawm titanium oxide zaj duab xis. Lub thickness ntawm oxide zaj duab xis cuam tshuam rau kev refaction thiab cuam tshuam ntawm lub teeb, uas ua rau muaj xim sib txawv ntawm cov titanium alloy. Cov khoom sib txawv sib txawv yuav hloov cov tsim nrawm thiab tuab ntawm cov xim oxide cov yeeb yaj kiab, yog li cuam tshuam cov xim ntawm titanium alloy.

Piv txwv li, thaum lub titanium alloy muaj cov kev faib ua feem siab dua ntawm txhuas, cov oxide zaj duab xis sai dua, thiab cov oxide zaj duab xis sai dua, thiab qhia lub teeb txho lossis silvery dawb xim. Hauv kev sib piv, titanium alloys muaj ntau molybdenum lossis vanadium muaj cov xim xiav, thiab cov yeeb yaj kiab cov yeeb yaj kiab ntau ntxiv yuav ua rau muaj kev cuam tshuam oxide. ntawm lub teeb, yog li qhia cov xim sib txawv.

3. Tus cawv ntawm lwm yam alloying cov ntsiab lus ntawm cov xim

Cov ntsiab sib txawv sib txawv tsis tsuas yog cuam tshuam rau cov tuab ntawm oxide zaj duab xis, tab sis kuj ncaj qha rau cov xim saum npoo ntawm cov titanium alloy. Piv txwv li:

1) txhuas (al): Aluminium yog ib qho ntawm cov ntsiab lus sib xws hauv titanium alloys. Nws tuaj yeem ua kom nrawm qhov tsim ntawm cov yeeb yaj kiab oxide, ua rau saum npoo ntawm titanium alloy tshwm sim dua txho lossis silvery dawb. Titanium alloys nrog lub ntsiab lus ntau dua feem ntau ua rau muaj lub zog ci ntsa iab thiab ntau dua cov xim.

2) Vanadium (V): Vanadium yog ib qho uas tuaj yeem txhim kho cov cua sov ua haujlwm ntawm cov xim kub, thiab nws cov cawv txiv ntoo tau los ntawm kev tsim cov oxide zaj duab xis. Cov yeeb yaj kiab oxide tsim nyob rau saum npoo ntawm titanium alloys muaj vanadium yuav tsim ntau qib xiav lossis liab qab, muab cov titanium alloy ib qho tshwj xeeb luster.

3) hlau (FE): hlau yog ib qho kev sib cais hauv titanium alloys. Nws feem ntau cuam tshuam rau cov tuab ntawm oxide zaj duab xis thiab ua rau muaj ntau yam metallic luster on rau saum npoo ntawm titanium alloys. Titanium alloys nrog cov ntsiab lus hlau siab feem ntau muaj lub ntsej muag kub lossis coppine.

4) Molybdenum (mo): Molybdenum tuaj yeem txhim kho lub zog thiab corrosion tsis kam ntawm titanium alloys. Nyob rau tib lub sijhawm, nws ntxiv kuj tseem tuaj yeem ua rau saum npoo ntawm titanium alloys tam sim no cov xim ci xws li kub thiab tooj. Titanium alloys nrog cov molybdenum cov ntsiab lus muaj cov yeeb yaj kiab oxide cov duab dub thiab nthuav tawm cov duab zoo nkauj tshaj plaws.

4. Tswj thev naus laus zis ntawm kev hloov xim ntawm titanium alloys

Txhawm rau kom tau txais cov xim zoo tagnrho ntawm titanium alloys hauv cov ntawv thov kev siv, ntau cov qauv siv tshuaj thiab kev kho mob oxidation thiab kev kho mob kom tswj tau cov xim titanium. Cov teebmeem xim sib txawv tuaj yeem tau los ntawm kev hloov cov feem ntawm alloying cov ntsiab hauv titanium alloys, lossis los ntawm kev kho qhov kub thiab txias thiab ntsuas lub sijhawm ntsuas kub.

Piv txwv li, titanium alloys tuaj yeem txhim kho ntxiv hauv cov xim los ntawm anodizing. Anodizing tsis tsuas yog txhim kho cov xeb pheej ua haujlwm ntawm titanium alloys, tab sis kuj tseem muaj cov khaub ncaws zoo dua thiab ruaj khov rau ntawm nws cov npoo av, yog li ua kom muaj cov xim nplua nuj. Nyob rau lub sijhawm no, cov xim ntawm cov yeeb yaj kiab oxide yuav hloov nrog qhov ceev tam sim no thiab electrolyte, txuas ntxiv enricliching cov xim hloov ntawm titanium alloy.

5. Cov ntaub ntawv thov ntawm titanium alloy xim

Cov xim hloov ntawm titanium alloy tsis yog tsuas yog kev ua kom muaj txiaj ntsig zoo, tab sis kuj ua lub luag haujlwm tseem ceeb hauv kev siv. Piv txwv li, nyob hauv daim teb ntawm Aerospace, cov xim hloov ntawm titanium alloy tuaj yeem siv kom paub qhov txawv ntawm cov hom sib txawv lossis cov khoom sib txawv. Nyob rau hauv cov cuab yeej kho mob, titanium alloys ntawm cov xim sib txawv tuaj yeem pab paub qhov txawv sib txawv hom kev cog hniav ntau yam thiab txhim kho cov neeg mob txoj kev ntseeg siab. Ib qho ntxiv, cov xim zoo nkauj ntawm titanium alloy kuj ua rau nws cov khoom tseem ceeb hauv cov hniav nyiaj hniav kub thiab kho kom zoo nkauj.

Los ntawm cov lus qhia saum toj no, nws tuaj yeem pom tau tias cov xim hloov ntawm titanium alloy yog ze rau nws li alloy muaj pes tsawg leeg. Cov ntsiab lus sib txawv tsis yog cuam tshuam rau cov tshuab ua haujlwm thiab corrosion tsis zoo ntawm titanium alloy los ntawm kev tsim ntawm oxide zaj duab xis. Hauv kev tsim khoom tiag tiag, cov tuam txhab tsim tawm tuaj yeem tau txais cov xim zoo tagnrho ntawm cov kev tswj hwm tagnrho
