Platinized titanium anodes synopsis
Titanium / Tantalum / Niobium-raws li platinum plated anode txheej txheem, nws siv electroplating los yog txhuam plating los yog nrog rau txheej txheej, cov tsos yog ci dawb, nrog rau cov yam ntxwv ntawm loj anode tawm tam sim no ceev thiab ntev kev pab cuam lub neej.
Platinized titanium anodes synergistically ua ke cov khoom zoo electrochemical ntawm platinum (Pt) nrog rau corrosion kuj thiab lwm yam ntxwv ntawm titanium. Lawv yog anodes ib txwm ua los ntawm electrochemical deposition ntawm ib tug nyias txheej ntawm platinum hlau los yog cov oxides ntawm platinum mus rau ib tug titanium substrate. Cov anodes no ua haujlwm li inert anodes nrog lub siab ntev thiab nyiam dua vim tias lawv nyob twj ywm insoluble hauv cov electrolytes.
Platinum yog cov hlau muaj txiaj ntsig uas paub txog nws cov txiaj ntsig zoo, suav nrog
- Siab tiv taus corrosion
- Kev tiv thaiv oxidation
- High hluav taws xob conductivity
- Muaj peev xwm ua raws li catalyst
- Kev ruaj ntseg tshuaj lom neeg siab
- Muaj peev xwm ua kom tiav qhov zoo tshaj plaws
Tus nqi qis qis rov qab los ntawm kev siv hluav taws xob siab ua rau platinum nyiam cov khoom siv anode. Tab sis vim nws tus nqi siab, tsuas yog ib txheej nyias ntawm platinum feem ntau yog plated ntawm cov khoom sib txawv corrosion xws li tantalum (Ta), niobium (Nb) lossis titanium (Ti) kom tau txais txiaj ntsig ntawm cov yam ntxwv zoo.
Platinized titanium anodes ua tshuab
Los ntawm electroplating los yog txhuam plating txheej txheem (xws li platinum txheej sintering manufacturing txheej txheem) cov platinum hlau ntawm titanium (tantalum, niobium), ib tug puas metallic txheej kuj yuav ua tau nyob rau hauv lub substrate. Cov khoom sib xyaw no muaj titanium hlau, platinum, oxides ntawm titanium thiab hlau sib txuas ntawm titanium thiab platinum.
platinum txheej sintering manufacturing txheej txheem: peb manufactures platinized titanium anode los ntawm kev siv thermal decomposition txheej txheem kom tau ib tug ntom hnav-resistant txheej ntawm platinum txheej. Lub anode nto yog hloov kho los txhim kho adhesion ntawm platinum thiab ua kom zoo dua qub ntawm txheej tuab, kuj txo cov txheej porosity imparting acid tsis kam rau cov anode. , Cov txheej txheem ntawm kev kho cua sov ntawm cov txheej txheem sib xyaw ua rau muaj kev hloov pauv hauv cov tshuaj lom neeg muaj pes tsawg leeg thiab morphology uas txhim kho nws cov khoom siv electrochemical. Lub platinum coated titanium anode no tuaj yeem tsim rau hauv bar, pas nrig, ntawv, mesh thiab lwm yam kev kho kom haum raws li koj cov kev xav tau tshwj xeeb.
Kev coj tus cwj pwm ntawm platinized titanium anodes
Platinum yog qhov zoo dua ntawm qhov anode sab nrauv vim tias nws muaj peev xwm tiv taus corrosion thiab tuaj yeem ua kom cov dej ntws tam sim no hauv feem ntau electrolyte media yam tsis tau ua rau kev tsim cov txheej txheem insulating ntawm nws tus kheej. Vim nws tsis corrode, nws tsis tsim cov khoom corrosion thiab li no tus nqi noj tsawg heev.
Platinum yog inert nyob rau hauv fused ntsev thiab acids, whereas nws yog yaj nyob rau hauv aqua regia. Tsis muaj kev pheej hmoo ntawm hydrogen embrittlement. (Koj tuaj yeem kawm txog hydrogen embrittlement nyob rau hauv tsab xov xwm Ib qho Taw Qhia rau Hydrogen Embrittlement.) Nws yog ib qho ntawm ob peb cov hlau tsis tshua muaj zog uas tiv taus cov chlorides ntawm seawater.
Titanium qhia tau hais tias muaj kev tiv thaiv zoo rau ib puag ncig marine (xws li dej hiav txwv). Nws tsis hnov mob nrog cov concentrated (80%) kev daws teeb meem ntawm cov hlau chlorides. Txawm li cas los xij, nws muaj kev cuam tshuam los ntawm hydrofluoric acid (HF) thiab kub hydrochloric acid (HCl) ntawm ntau dua. Txawm tias hydrogen peroxide thiab kub nitric acid tuaj yeem tua titanium. Oxidizing cov neeg ua haujlwm ib txwm tsis tawm tsam titanium vim tias nws yooj yim tsim cov oxide txheej tiv thaiv. Txawm li cas los xij, cov khoom tsis-oxidizing xws li sulfuric acid (siab dua 5% concentration) thiab phosphoric acid (siab dua 30%) tuaj yeem tua titanium. Los ntawm hydrogen embrittlement point of view, titanium fares zoo dua tantalum li anode khoom.
Qhov zoo ntawm platinized titanium anodes
Platinum muaj qhov zoo ntawm electrochemical inertness, txhua yam muaj zog, ua haujlwm tau zoo thiab cov khoom siv hluav taws xob zoo. Txawm li cas los xij, nws yog txwv tsis pub kim. Kev loj hlob ntawm platinum ntawm titanium thiab platinum ntawm tantalum (plated as well as cladded) cov ntaub ntawv tau qhib qhov ua tau ntawm kev siv cov khoom siv anode rau hlau xov thiab kev tiv thaiv cathodic hauv cov ntawv thov tseem ceeb.
Thaum siv rau anodes hauv aqueous media xws li dej hiav txwv, cov titanium tsim ib txheej ruaj khov ntawm insulating oxide zaj duab xis rau ntawm qhov chaw uas ruaj khov hauv qab qee qhov kev tawg, yog li tiv thaiv cov dej ntws tam sim no ntawm cov xov xwm aqueous thiab cov anode. Nyob rau hauv ib puag ncig marine, cov oxide tsim rau ntawm titanium muaj peev xwm tiv taus 12 volts, dhau ntawm qhov thaiv thaiv thaiv kev tawg thiab tam sim no ntws pib txheej txheem corrosion.
