STUDIES CONCERNING NICKEL ELECTRODEPOSITION FROM WATTS BATH WITH ADDITION OF POLYVINYL PYRROLIDONE (PVP)
This work is a study about the influence of polyvinyl pyrrolidone (PVP) on the nickel electroplating processes from Watts bath. PVP is a wetting agent which improves the quality of deposited layers. Its action seems to be related to the inhibition of adsorption of (NiOH)+ species on the cathode surface. Even if there are some studies about the influence of PVP in electrochemical processes, this trend is new and our results could promote this additive for future commercial applications.
