The rare earth compound LaCl3 （ReC） was added to the modified Watts bath to prepare nanocrystalline Ni by the use of pulse electrodeposition. The microstructure was analysed by TEM and SEM. The results are shown as follows：The surface fineness of the coating is improved by the addition of ReC, at same time the corrosion resistance of coatings is improved greatly. The best corrosion resistance will be obtained when the concentration of LaCl3 is 1 g/L.
