ChemInform Abstract: Pulsed Electrodeposition of Ni‐Mo Alloys.

Abstract

ChemInform Abstract The effect of pulsing the current on the composition, internal stress, and mechanical properties of Ni-Mo electrodeposits is studied (Cu-substrate, plating bath: nickel sulfate-sodium molybdenate-sodium citrate, pH 10.5). The Mo content increases with peak current density and to a lesser degree with increasing off-time. High-frequency pulse plating at peak current densities of 25 mA/cm2 results in increased yield and tensile strengths. Deposition of alternate layers of different composition results in improved mechanical properties after annealing at 300 rc C.
