Niobium plating

Koj tuaj yeem phaj ntau yam hlau rau niobium txhawm rau txhim kho qhov zoo koj xav tau rau koj daim ntawv thov. Cov txheej txheem ntawm plating rau cov hlau no yog qhov nyuaj dua li qee qhov lwm tus, thiab koj yuav tsum ua tib zoo npaj qhov chaw ua ntej plating pib. Txawm li cas los xij, nrog cov cuab yeej zoo thiab kev txawj ntse, nws muaj peev xwm ua tau.

Ntau cov txheej txheem tau siv los npaj niobium rau plating rau nws. Cov txheej txheem no yuav cuam tshuam nrog cathodizing lub substrate nrog hydride overlay, uas tshem tawm etching thiab tso cai rau kev txhim kho kev tswj ntawm qhov ntev ntev. Ib feem kuj tuaj yeem raug cua sov thiab nqus hluav taws xob thiab anodizing. Qhov saum npoo kuj tseem tuaj yeem raug ntxuav los txhim kho kev ua haujlwm ntawm cov txheej txheem plating, uas tuaj yeem cuam tshuam cov khoom siv hauv cov tshuaj ntxuav alkaline thiab ntau lwm yam txuj ci.

Cov txheej txheem plating siv ib txoj kev hu ua electrodeposition los tso ib txheej rau hauv qhov chaw hu ua substrate. Hauv qhov no, lub substrate yog niobium. Nyob rau hauv ib tug raug electroplating txheej txheem, lub substrate yog muab tso rau hauv ib tug tov los yog plating da dej uas muaj yaj ions ntawm cov hlau uas yuav tsim cov txheej. Tom qab ntawd cov ions coj mus rau qhov zoo thiab cov substrate yuav siv rau qhov tsis zoo. Qhov no ua rau cov ions tso rau ntawm qhov chaw ntawm lub substrate.

Nyob ntawm qhov tshwj xeeb ntawm cov txheej txheem siv, koj tuaj yeem xaus nrog cov txiaj ntsig sib txawv. Qhov no yog vim li cas nws yog ib qho tseem ceeb kom muaj cov txheej txheem tshwj xeeb hauv qhov chaw kom ntseeg tau tias muaj txiaj ntsig zoo, ua tau zoo. Cov tshuaj chemical ntawm cov tshuaj plating, qhov kub ntawm cov tshuaj plating, qhov hluav taws xob tam sim no, qhov ntev ntawm lub sijhawm tam sim no tau thov, thiab qhov kev ncua deb ntawm cathode thiab anode yog tag nrho cov kev hloov pauv tseem ceeb uas yuav tsum tau ua kom zoo. Zoo.

Koj tuaj yeem phaj hlau rau ntau yam sib txawv, suav nrog kev txhim kho corrosion, lub zog, kub tsis kam, hluav taws xob conductivity, lossis lwm yam khoom muaj txiaj ntsig. Thaum plating ntawm niobium, koj tuaj yeem ua li ntawd txhawm rau txhim kho qhov chaw tiv thaiv oxidation lossis cua sov lossis cov kua qaub. Oxidation yog ib qho nyuaj thaum ua hauj lwm nrog niobium vim hais tias cov hlau yuav tsum tau raug rau qhov chaw tiv thaiv yog tias nws raug kub los yog nruab nrab.

Siv cov txheej txheem oxidation zoo dua li niobium tso cai rau koj kom muaj cov txiaj ntsig zoo ntawm cov hlau hauv qhov chaw uas oxidation tuaj yeem ua teeb meem. Qee lub sij hawm txheej txheej txheej ua raws li cov txheej txheem txi. Nws yuav oxidize los yog corrode thiab tiv thaiv lub substrate hauv qab.

Lwm yam laj thawj rau plating ntawm niobium tuaj yeem suav nrog nce qhov tuab ntawm qhov chaw, txhim kho qhov sib xws ntawm qhov chaw, txhim kho adhesion ua ntej siv cov xim los yog lwm yam txheej, los yog txhim kho cov tsos. Qee zaum, ntau txheej txheej txheej yuav raug siv los txhim kho lub peev xwm ntawm lwm cov hlau kom ua raws li cov substrate.
