Feem ntau cov tshuab hluav taws xob yuav tsum tau kho saum npoo, qhov hu ua electroplating, ntawm qhov ib sab, yog los tiv thaiv lub dav hlau caij nplooj ntoos hlav lub hauv paus los ntawm kev xeb; ntawm qhov tod tes, nws yog txhawm rau ua kom qhov ua tau zoo ntawm lub davhlau ya nyob twg thiab tsim thiab tswj kev sib cuag ntawm cov dav hlau. Kev cuam tshuam, tshwj xeeb yog kev tswj hwm zaj duab xis. Hauv lwm lo lus, nws ua kom yooj yim kom ua tiav hlau-rau-hlau sib cuag.
Feem ntau cov kab rov tav yog ua los ntawm tooj liab hlau, thiab feem ntau yog corroded hauv ib puag ncig siv, xws li oxidation thiab sulfide. Lub dav hlau plating yog cais cov reed los ntawm ib puag ncig los tiv thaiv kev xeb. Cov khoom siv plating, tau kawg, yuav tsum tsis xeb, tsawg kawg hauv ib puag ncig daim ntawv thov.
Kev ua kom zoo ntawm kev ua haujlwm saum npoo av tuaj yeem ua tiav hauv ob txoj hauv kev. Ib qho yog kev tsim qauv ntawm lub davhlau ya nyob twg los tsim thiab tswj kev ruaj ntseg davhlau ya nyob twg hu rau interface; lwm qhov yog tsim kom muaj kev sib cuag xim hlau, xav kom tsis muaj zaj duab xis saum npoo av tshwm sim thaum lub qhov ntxig. Tej zaum tawg.
Qhov sib txawv ntawm ob daim ntawv uas tsis muaj txheej txheej zaj duab xis thiab txheej txheej txheej tawg kuj yog qhov sib txawv ntawm cov hlau zoo plating thiab cov hlau tsis muaj nqi plating. Noble hlau plating, xws li kub, palladium, thiab lawv cov alloys, yog inert thiab tsis muaj zaj duab xis nws tus kheej. Yog li ntawd, rau cov kev kho saum npoo av, kev sib cuag ntawm cov hlau yog&"tsis siv neeg &".
Txhawm rau kom ntseeg tau tias qhov ua tau zoo ntawm lub davhlau ya nyob twg tsis cuam tshuam los ntawm lwm yam, xws li kev sib kis, cov kab mob sib kis, kev yaig hauv dav hlau, thiab lwm yam Tsis yog hlau hlau, tshwj xeeb yog cov hlau thiab cov hlau lead thiab lawv cov alloys, npog ib txheej ntawm cov yeeb yaj kiab oxide, tab sis thaum tso, cov yeeb yaj kiab oxide tau tawg yooj yim, thiab tsim kom muaj thaj chaw hu xov tooj.
Ib qho ntxiv, rau cov hlau uas muaj cov nplaum tsis zoo, tooj liab puag feem ntau yog siv los txhim kho cov nplaum ua ntej electroplating; kev coj ua ntawm cov ntaub ntawv raw xws li hlau thiab phosphor tooj liab feem ntau qis dua 20%, uas tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua rau qis-cuam tshuam txuas. Yog li ntawd, kev tiv thaiv tuaj yeem txo qis tom qab txheej txheej txheej yog electroplated nrog cov hlau ua kom zoo xws li kub.
