Electrochemical Studies of Nickel from Sulfate bath with Succinic acid

Abstract

In this research we studied the mechanism of the reaction in the medium [Nickel(II)-Succinic acid-Water] by using electrochemical methods.

This study showed that the deposition process of nickel(II) from its electrolytes on copper plates carried out in steady state galvanostatic and potentiostatic techniques. The deposition potential does not change throw painting time, and thus the surface of the electrode is homogeneous, the possibility of discharging nickel ions on any point of the surface is being equivalent, so the reduction of the nickel ions is followed by forming a smooth mirror-bright deposit.

Then we determined the basic composition for nickel painting electrolyte and the best conditions for exploitation it.

So we have got an argentous, glossy, scratch-resistant, steady nickel painting. Its thickness is about (25) microns and the yield is up to (85%).

Thus, this study could introduce a new electrolyte for painting with nickel which has good properties, free from defects.
