摘　　要：本文在镍基上电沉积Ni-Mo合金层,用W^+束注入,得到活性和稳定性极佳的新型析氢电极.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 H2SO4solu-tion and 295mV (38℃) in 1mol/ dm3NaOH solution. The cathodes showed stable potentials during water electrolysis by 300mA/ cm2 in acid medium more than 16 days. The strike-resistant stability of the cathodes was higher than others ones.
