The electrodes containing Ni, W, Mo were obtained by implanten W into Ni-Mo surface alloys. The alloys was prepared by electrodepositing on Ni substrate. The hydrogen overvoltage decreasing comparing with mild steel is 235mV (48℃) in 0.5mol/dm^3 H~2SO~4 solution and 295mV (38℃) in 1mol/dm^3 NaOH solution. The cathodes showed stable potentials during water electrolysis by 300mA/cm^2 in acid medium more than 16 days. The strike-resistant stability of the cathodes was higher than others ones.
