摘要：
Nanocrystalline Ni and Ni-Fe alloy coatings were synthesised by brush plating using soluble anode, and the corrosion characteristics of nanocrystalline Ni, Ni-5.84% Fe and Ni-13.49% Fe were investigated by soak method and electrochemical polarisation method respectively. The nanocrystalline Ni-Fe alloy coatings showed higher hardness and smaller grain size than that of Ni coating. Ni-13.49% Fe alloy coating exhibited better corrosion resistance in 3.5 wt-% NaCl solution than the nanocrystalline Ni coating and the Ni-5.84% Fe coating, which indicats that the corrosion resistant of nanocrystalline Ni coating can be improved by adding appropriate amount of Fe.
