Microstructure and surface mechanical properties of pulse electrodeposited nickel

► Ni coatings were deposited on carbon steel substrates using dc and pulse electrodeposition. ► Pulse electrodeposition produced finer Ni grains compared to dc plating. ► Size of Ni grains increased with deposition time. ► Grain growth occurred in preferred (2 0 0) orientation. ► Pulse plated Ni exhibited higher hardness, creep and friction coefficient and lower modulus of elasticity.
