摘　　要：为了提高电沉积镍钨合金薄膜的沉积速率和降低能耗,使用了磁场诱导电沉积技术。研究了垂直于电场的磁场对镍钨合金电沉积时的电流、速率以及镀层形貌和结构的影响。结果发现,磁场和电场相互作用产生的磁流体力学效应有利于增大极化电流,提高沉积速率和细化合金晶粒。0.8 T磁场作用下,镍钨合金的沉积电流增加了30%,沉积质量提高了40%。电沉积镍钨合金为Ni17W3结构。在磁场作用下,镀态镍钨合金的显微硬度明显提升。Magnetic-field-induced electrodeposition technology was used to improve the deposition rate of Ni–W alloy film and reduce energy consumption.The effect of a magnetic field normal to the electric field on the deposition current and rate as well as the morphology and microstructure of Ni–W alloy film.It was found that the magnetohydrodynamic effect caused by the interaction of magnetic field and electric field could increase the polarization current,improve the deposition rate,and refine the alloy grains.Under a magnetic field of 0.8 T,the current during the electrodeposition of Ni–W alloy was increased by 30%,and the mass of deposit was increased by 40%.The as-electrodeposited Ni–W alloy under a magnetic field is of Ni17W3 structure and has an improved microhardness.
