Abstract
The effects of butynediol, coumarin, sodium naphthalenesulphonate, sodium benzenesulphonate and toluenesulphonamide on the electrical resistivity, mean grain diameter and hardness of nickel deposited from a Watts type solution are reported. The resistivity is dependent on type of addition, its concentration and the thickness of the deposit. The effect of thickness is that a very flat maximum is produced in between 10 and 20 μm. The absolute values of the resistivity vary from ≈70 μΩ-mm for deposits from a pure Watts bath to ≈120 μΩ-mm for deposits from baths containing coumarin.
The results are correlated with the size and active groups of the molecules through their adsorption-desorption behaviour. The adsorption of butynediol follows the Langmuir adsorption.
