Tantalum carbide txheej yog cov cuab yeej siv dav siv hauv kev kho mob uas tuaj yeem txhim kho corrosion ntawm cov ntaub ntawv. Tantalum carbide txheej tuaj yeem txuas rau saum npoo ntawm substrate los ntawm kev npaj sib txawv, xws li tshuaj vapor deposition, lub cev vapor deposition, sputtering, thiab lwm yam., los tsim ib tug uniform thiab tuab tiv thaiv txheej, uas zoo thaiv kev sib cuag ntawm cov khoom thiab qhov nruab nrab ib puag ncig, yog li txhim kho corrosion kuj.
Cov nram qab no yog ob peb lub ntsiab mechanisms rau tantalum carbide txheej los txhim kho corrosion kuj ntawm cov ntaub ntawv:
1. Kev rho tawm barrier cuam tshuam:
TANTALUM carbide txheej muaj qhov ntom ntom ntom thiab lub siab tawv, uas tuaj yeem tiv thaiv corrosive los ntawm cov tshuaj sab nraud xws li acids, alkalis, thiab ntsev. Cov txheej txheej ntom ntom tsim los ntawm tantalum carbide txheej tuaj yeem txo qhov permeability ntawm cov khoom nto thiab tiv thaiv kev nkag mus ntawm cov xov xwm corrosive, yog li txhim kho corrosion kuj ntawm cov khoom.
2. Tshuaj stability:
Tantalum carbide txheej muaj cov tshuaj lom neeg ruaj khov thiab tuaj yeem tswj hwm nws cov qauv thiab kev ua haujlwm yam tsis muaj kev hloov pauv tseem ceeb hauv ib puag ncig huab cua. Tantalum carbide yog ib yam khoom uas muaj cov tshuaj lom neeg tsis zoo uas tuaj yeem tiv thaiv kev yaig ntawm cov xov xwm muaj zog xws li acids, alkalis, thiab oxidants. Tsis tas li ntawd, vim lub siab hardness thiab tsis tshua muaj kev sib txhuam coefficient ntawm tantalum carbide txheej, nws kuj tuaj yeem txo qhov kev sib txhuam thiab hnav ntawm cov khoom siv thiab ib puag ncig nruab nrab thiab ntev kev pab cuam lub neej ntawm cov khoom.
3. Kev kho tus kheej muaj peev xwm:
Tantalum nyob rau hauv tantalum carbide txheej muaj qee qhov kev kho tus kheej. Thaum cov txheej txheej raug khawb, hnav lossis qee qhov puas, tantalum tuaj yeem ua rau cov pa oxygen, chlorine thiab lwm yam hauv nruab nrab corrosive los tsim cov tantalum compounds xws li tantalum oxide thiab tantalum chloride, sau qhov tsis xws luag ntawm cov txheej txheej, thiab rov ua dua. tsim ib zaj duab xis tiv thaiv. Lub peev xwm kho tus kheej no tuaj yeem ua kom qeeb ntawm cov txheej txheem corrosion thiab ncua kev puas tsuaj ntawm txheej.
4. conductivity:
Tantalum carbide txheej muaj qhov ua tau zoo thiab tuaj yeem tsim cov txheej txheem electrochemical tiv thaiv kom tsis txhob ntws ntawm corrosion tam sim no. Thaum lub npoo ntawm txheej yog corroded los ntawm corrosive nruab nrab, tantalum yuav adsorb ions nyob rau hauv ib puag ncig ib puag ncig los tsim ib tug ruaj khov muaj peev xwm sib txawv, tiv thaiv qhov kev ntawm corrosion tam sim no, thiab yog li tiv thaiv corrosion.
5. Ntxiv cov additives:
Txhawm rau txhawm rau txhim kho kev txhim kho corrosion ntawm tantalum carbide txheej, cov tshuaj ntxiv tuaj yeem ntxiv thaum lub sijhawm txheej txheej txheej txheej txheej. Piv txwv li, ntxiv cov tshuaj ntxiv xws li potassium thiab oxides tuaj yeem txhawb kev muaj qhov sib xws, yog li txhim kho cov xeb tawm tsam ntawm txheej.
Hauv luv luv, tantalum carbide coatings tuaj yeem txhim kho qhov kev tiv thaiv corrosion ntawm cov ntaub ntawv los ntawm cov txheej txheem xws li kev sib cais barrier nyhuv, tshuaj stability, nws tus kheej-kho muaj peev xwm, conductivity thiab additive ntxiv. Qhov no muaj cov txiaj ntsig tseem ceeb hauv ntau qhov chaw, xws li kev lag luam tshuaj lom neeg, lub zog, aerospace, thiab lwm yam.
