In this work, nanocrystalline nickel coatings were electrodeposited from a Watts bath using direct (DC) and pulsed (PC) current. Effect of deposition conditions on the morphology, hardness, grain size, surface roughness and corrosion resistance of nickel coatings were investigated. Ni films deposited by PC method exhibited greater hardness values and smaller crystallite size compared to those deposited by DC method. A preferential crystallographic orientation or texture was found in the nickel films depending upon the electrodeposition pulse shape, as it is polycrystalline in the DC electrodeposited films, while exhibit <111> crystallographic growth direction for PC method. Corrosion evaluation results showed that the PC electrodeposited nanocrystalline Ni films have higher corrosion resistant compared to those deposited with the DC method in 2 mol/liter NaOH solution.
