Abstract
This research work investigated the effect of current density, bath
concentration, bath soIution volume and electroplating time on nickel
electroplating of low carbon steel. Varying voltage between 0.3 and 0.8 V,
bath concentration between 0.27 g/cm3 (0.79 rno~ddan d 0.35 glcm3 (1.02
mo~dmp, electropfig time between 1Q and 30 minutes and bath solution
volume between 200 and 700 cm3, the effect of these process variables on
electroplating was studied. The temperature was kept in conformity with
Watt's method at 50 SQC. It was observed .that a batfi conceniration of 0.31
g/cm3 (0.89 MoVM) concentdon gave the best nickel deposit at 0.5V for
15 minutes. This would correspond to a Watt solution of composition: nickel
sulphate-230 gll, nickel chIoride46.5 g/l and boric acid-30.8 dl with a pH of
4.18. Higher Watt bath concentralion did not yield good results as plating
thickness decreaged and there was no luster. It was aIso observed that
incmsing time of plating served to increase pIating thickness and did not
affect brightness of plating. However non-uniform nickel deposition was
observed for longer plating time. Increase in voltage served to increase rate of
electrodeposition with the exceptions of 0.7 V where a long streak of plating
