The influence of the additive 1,3,6 naphthalene trisulfonic acid on the microstructure and hardness of electrodeposited nickel layers was investigated. The microstructure was characterized using transmission electron microscopy; the Vickers hardness was measured in cross sections. The additive was found to refine the grain size resulting in and enhanced hardness. The efficiency of the additive in enhancing the hardness was found to depend on the current density during deposition.
