6 Yam Koj Yuav Tsum Paub Txog Platinized Titanium Anodes (1)
Muab piv rau ob hom kev tiv thaiv cathodic (CP), sacrificial anode cathodic tiv thaiv (SACP) siv anodes sacrificial anodes ua los ntawm cov khoom uas tsis muaj nuj nqis tshaj cov qauv raug tiv thaiv thiab maj mam noj. Hauv qhov sib piv, kev txaus siab rau kev tiv thaiv cathodic tam sim no (ICCP) siv cov khoom siv sab nraud nrog qhov feem ntau qis lossis tsis siv cov anode. Ntau yam khoom siv tau siv rau ICCP systems, tab sis cov khoom siv tshiab ua ke tau pom cov lus cog tseg rau ntau daim ntawv thov.
# 1: Sib txuas Platinum thiab Titanium rau Kev Tiv Thaiv Kev Tiv Thaiv Zoo
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 cov anodes ib txwm ua los ntawm electrochemical deposition ntawm ib txheej tawv nqaij 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 tau raws li cov 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 cov hluav taws xob 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-resistant xws li tantalum (Ta), niobium (Nb), lossis titanium (Ti) kom tau txais txiaj ntsig ntawm cov yam ntxwv zoo.
Los ntawm electroplating lub platinum hlau ntawm titanium, cov khoom siv hlau nplaum kuj tuaj yeem ua rau ntawm lub substrate. (Kom paub ntxiv txog cov txheej txheem no hauv Yuav Ua Li Cas Hlau Coatings Tiv Thaiv Cov Hlau los ntawm Corrosion.) Cov khoom sib xyaw no muaj cov hlau titanium, platinum, oxides ntawm titanium, thiab cov hlau sib txuas ntawm titanium thiab platinum. Cov txheej txheem ntawm kev kho cua sov kho cov txheej txheem sib xyaw ua rau muaj kev hloov pauv hauv tshuaj lom neeg muaj pes tsawg leeg thiab morphology uas txhim kho nws cov khoom siv hluav taws xob.
Kev txais yuav ntawm platinum-plated thiab platinum-cladded anodes tau muab cov kev xaiv tshiab thiab kev xaiv rau cov neeg tsim qauv ntawm kev tiv thaiv cathodic tam sim no (ICCP), vim tias cov txiaj ntsig ntxiv muab los ntawm anodes ua los ntawm kev sib xyaw ntawm platinum ntawm titanium thiab platinum ntawm tantalum yog kev ua si. hloov pauv hauv kev lag luam kev tiv thaiv corrosion, yog li ua rau lawv cov kev siv dav dav.
Galvanic cov ntaub ntawv feem ntau siv hauv anodes, xws li magnesium thiab zinc, tsis yog cov khoom nyiam vim lawv loj heev, kim kim, thiab yuav tsum tau hloov ntau zaus.
