In this paper, a perpendicular experiment was conducted by using 4 key process parameters, such as concentration of sodium tungstate, current density, PH value and operating temperature, which have obvious influence on the electrodeposition of Ni-W alloy nanocrystalline. By extreme difference analysis, the influence of multi-factors on the deposition rate and microhardness and surface quality of the nanocrystalline alloy coatings was studied in detail. By further contrastive experiment, the influence of single-factor on the electrodeposition of Ni-W alloy nanocrystalline was also discussed, which will provide basis for the preparation of Ni-W alloy nanocrystalline.
