Cov txheej txheem electroplating yuav muab kev tiv thaiv zoo rau uranium thiab uranium alloys. Qhov tseem ceeb tshaj uas cuam tshuam txog kev tiv thaiv kev kub ntxhov ntawm cov txheej ntawm lub substrate yog qhov denseness thiab thev yuam kev ntawm lub txheej. Cov hlau chloride etchant tuaj yeem muab ib qho dej ntxaum tsis haum kom lub txheej txheem zoo nkauj txuas nrog lub substrate thiab tseem ruaj khov.
Hauv dej thiab chloride ntsiab, ntom Ni plating exhibits qee yam kev tiv thaiv ntawm cov khoom uranium thiab uranium. Thaum cov kaus poom yog tam sim no, tus nqi txhim khu yuav nce ntxiv vim yog lub plawv hauv chaw xuab zeb. Zinc txheej txheem muab ib qho sacrificial anode rau electrochemical kev tiv thaiv ntawm uranium thiab uranium alloys. Tus chromate-passivated Ni + Zn txheej tau pov thawj zoo tiv thaiv thiab kev tiv thaiv kev tiv thaiv kev tiv thaiv rau uranium thiab uranium alloys. Txawm hais tias Zn-Ni alloy txheej muaj kev tiv thaiv zoo corrosion, nws yuav muab ob npaug rau kev tiv thaiv rau lub cev muaj teeb meem thiab sacrificial anodes rau uranium thiab uranium alloys. Txawm li cas los xij, muaj teeb meem xws li denseness thiab passivation ntawm coatings, uas ua rau lawv tsis resistant uranium thiab uranium alloys. Ni + Zn ob chav plating. Nrog txoj kev tshawb nrhav zoo ntawm Zn-Ni alloy electroplating thiab kev sau ntawv, Zn-Ni alloy yuav ua rau nws cov kev tiv thaiv zoo tshaj corrosion thiab yuav tsum tau thov hauv corrosion ntawm uranium thiab uranium alloy.
Txoj kev tiv thaiv kev kub ntxhov ntawm uranium thiab uranium alloys muaj ib qho teeb meem ntawm pluag txheej nruj, uas yog vim cov adsorption ntawm hydrogen molecules rau cathode side reaction nyob rau txheej txheem plating. Yuav kom ntxiv txhim kho qhov txheej txheem ntawm lub plating txheej thiab txhim kho lub cev thiab tshuaj ntawm lub plating txheej, mem tes plating yuav siv tau los ua ib txheej plating nrog finer crystallinity, sab hauv kev nyuaj siab hauv plating txheej, thiab cov ntsiab lus qis hydrogen. Tsis tas li ntawd, cyanide-free galvanizing yuav tsum raug siv los tshem tawm qhov muaj kev ntshai ntawm cyanide
