Dab tsi tuaj yeem corrode tantalum?

Tantalum paub txog nws cov kev tiv thaiv corrosion zoo heev, tab sis qee qhov xwm txheej thiab cov khoom yuav ua rau tantalum corrode. Qee yam uas tuaj yeem ua rau tantalum corrosion muaj xws li:

1. Muaj zog alkali: Tantalum muaj kev cuam tshuam rau corrosion nyob rau hauv ib puag ncig alkaline heev, tshwj xeeb tshaj yog nyob rau hauv high kub.

2. Hydrofluoric acid: Tantalum raug tawm tsam los ntawm hydrofluoric acid, tshwj xeeb tshaj yog nyob rau hauv siab thiab kub.

3. Qee Halogens: Tantalum tuaj yeem cuam tshuam nrog qee yam halogens (xws li fluorine thiab chlorine) ntawm qhov kub thiab txias, ua rau muaj peev xwm corrosion.

4. Molten salts: Tantalum yog qhov muaj feem cuam tshuam los ntawm qee cov ntsev molten, tshwj xeeb tshaj yog thaum kub.

Nws yog ib nqi sau cia hais tias nyob rau hauv feem ntau, tantalum exhibits zoo heev corrosion kuj, ua rau nws haum rau siv nyob rau hauv heev corrosive ib puag ncig. Txawm li cas los xij, nyob rau hauv qee qhov xwm txheej uas muaj cov khoom siv saum toj no, kev ceev faj thiab kev txiav txim siab yuav tsum tau coj los ua kom muaj kev tiv thaiv corrosion txuas ntxiv ntawm tantalum Cheebtsam.

Dab tsi yog qhov zoo tshaj plaws tiv thaiv corrosion rau bolts?

Qhov zoo tshaj plaws los tiv thaiv corrosion rau bolts nyob ntawm daim ntawv thov tshwj xeeb thiab ib puag ncig tej yam kev mob uas cov bolts yuav raug. Cov hauv qab no yog qee qhov kev kho bolt anti-corrosion:

1. Stainless hlau: Stainless hlau bolts, tshwj xeeb tshaj yog cov uas muaj siab chromium thiab npib tsib xee cov ntsiab lus, muaj zoo heev corrosion kuj. Stainless hlau bolts yog haum rau ntau daim ntawv thov, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig raug rau ya raws thiab tej yam tshuaj.

2. Txheej: Ntau txheej txheej tuaj yeem siv rau bolts los txhim kho lawv cov kev tiv thaiv corrosion. Cov no suav nrog galvanizing, galvanizing thiab epoxy txheej. Txhua hom txheej muab qhov sib txawv ntawm kev tiv thaiv corrosion thiab tuaj yeem xaiv raws li cov xwm txheej tshwj xeeb.

3. Corrosion-resistant alloys: Bolts ua los ntawm corrosion-resistant alloys xws li titanium, nickel alloys, los yog tshwj xeeb alloys xws li Inconel los yog Monel yog haum rau daim ntaub ntawv uas yuav tsum tau ib tug siab ntawm corrosion kuj.

4. Polymer txheej: Bolts tuaj yeem coated nrog cov ntaub ntawv polymer xws li PTFE (Teflon) los muab kev tiv thaiv kev tiv thaiv corrosion. Cov coatings no tshwj xeeb tshaj yog siv rau hauv daim ntawv thov uas xav tau tshuaj tiv thaiv thiab tsis-stick zog.

5. Kev Tiv Thaiv Cathodic: Qee qhov xwm txheej, bolts tuaj yeem tiv thaiv corrosion los ntawm kev tiv thaiv cathodic, xws li kev siv cov anodes txia lossis kev qhuas cov tshuab tam sim no.

Thaum xaiv qhov zoo tshaj plaws bolt los tiv thaiv corrosion txoj kev, nws yog ib qho tseem ceeb uas yuav tau xav txog tej yam kev mob, cov khoom ntawm lub ntsia liaj qhov rooj, thiab cov kev ua tau zoo ntawm daim ntawv thov. Kev sab laj nrog tus kws tshaj lij corrosion lossis cov khoom siv hluav taws xob tuaj yeem pab txiav txim siab qhov tsim nyog tshaj plaws los tiv thaiv corrosion rau ib daim ntawv thov tshwj xeeb.
