Abstract
A quantitative analysis was made of the post-deposition increase of the internal tensile stress in nickel and cobalt electrodeposits using an approach based on the diffusion-elastic phenomena. Equations were derived for the determination of the amount and the effective diffusion coefficient of hydrogen, which leaves the deposit immediately after plating. The experimental results are processed using these equations and the results are compared with data in the literature. The role played by hydrogen desorption in increasing the tensile stress after the electrodeposition current is switched off was confirmed.
