The impact of different electrodeposition conditions in pulse plating process on the composition, apparent morphology and HER (hydrogen evolution reaction) activity of Ni-Mo-W coating was investigated. The molybdenum content in the coating increases with the addition of molybdenum salt until to a constant value (about 39.0 wt %), while the corresponding HER overpotential decreases to the minimum value. The Ni-Mo-W coating with amorphous structure (c.a. 39.0 wt% Mo) prepared by pulse plating is smooth without cracks; moreover, it shows a good activity (353 K, eta200 = 3D62 mV) e. After galvanostatic electrolysis for 100 h in 33 wt% NaOH solution, the amorphous structure was destroyed due to the dissolution of Mo, however, the bubble phenomenon did not happen, which shows the higher stability and corrosion resistance.
