Khoom Description
Qhov zoo ntawm niobium-based platinum-coated electrodes:
Platinum muaj kev tiv thaiv corrosion zoo heev, conductivity thiab catalytic kev ua haujlwm, thiab nws cov khoom siv hluav taws xob muaj zog heev. Nws yog ib qho khoom siv tsis zoo hauv ntau cov txheej txheem electrolysis. Txawm li cas los xij, platinum yog cov hlau muaj txiaj ntsig, thiab tus nqi ntawm kev siv nws ua ib qho khoom electrode yog siab. Niobium yog lub valve hlau, thiab nws cov oxide zaj duab xis muaj nuj nqis "valve", uas yog, nws tsis ua hluav taws xob hauv lub xeev anode, tab sis tuaj yeem ua hluav taws xob hauv lub xeev cathode. Thaum platinum electroplated ntawm hlau niobium, txawm tias muaj qhov hws ntawm cov txheej txheej, corrosion yuav tsis tshwm sim thaum lub anode tam sim no dhau, vim hais tias cov matrix nyob rau hauv lub pores yuav cia li random puv nrog nws tus kheej oxide zaj duab xis, uas muaj. tsis tshua muaj zog corrosion kuj. .
Lub niobium-raws li platinum-plated electrodes uas ua los ntawm peb lub tuam txhab txais ib tug tshwj xeeb electroplating txheej txheem. Ib txheej ntawm platinum yog plated rau ntawm qhov chaw tshwj xeeb kho niobium substrate. Nws tuaj yeem ua tiav plated lossis ib nrab plated. Qhov saum npoo ntawm cov khoom yog nyiaj-dawb, txheej txheej yog zoo ib yam thiab zoo, kev sib xyaw ua ke yog ruaj khov, thiab cov khoom tso zis muaj xws li loj tam sim no thiab lub neej ua haujlwm ntev. Niobium muaj cov khoom siv hluav taws xob zoo dua thiab tiv thaiv corrosion dua li titanium, tab sis niobium yog kim.

Ehisen siv cov txheej txheem tshwj xeeb electroplating thiab thev naus laus zis los tsim niobium-based platinum-plated electrodes. Ua ntej, cov hlau niobium substrate tau muab tso rau hauv cov kua qaub kom tshem tawm cov niobium oxide zaj duab xis thiab hydrogenate saum npoo ntawm substrate los tsim cov yeeb yaj kiab ua haujlwm. Ib daim ntawv cog lus quasi-metallic yog tsim los ntawm niobium matrix, niobium hydride thiab txheej hlau, ua rau txheej txheej zoo sib txuas. Thib ob, lub tshuab txais niobium substrate yog ntxuav nrog dej deionized, thiab tom qab ntawd sai sai rau hauv cov tshuaj platinum plating, uas tuaj yeem yog platinum plating tag nrho lossis ib feem platinum plating. Tom qab txheej txheem kev kho deg tshwj xeeb, qhov chaw ntawm peb lub tuam txhab cov khoom yog ntom silvery dawb. Cov nyhuv electroplating zoo tshaj plaws tuaj yeem tau txais los ntawm kev tswj qhov kub thiab txias, concentration thiab tam sim no ntawm cov tshuaj plating. Cov khoom lag luam muaj qhov zoo ntawm cov txheej txheem sib xws thiab du, ruaj khov, cov khoom tso tawm loj tam sim no, thiab lub neej ua haujlwm ntev.
