Abstract The effect of annealing temperature on the morphology, phase composition, micro-hardness and corrosion resistance of Ni-W coating were investigated. The results show that an unidentified phase(2θ ≈41.4°) was presented in the as-plated Ni-W coating and then disappeared after annealing treatment. Meanwhile, NiW and Ni4W were precipitated in the annealed coating. As the annealing temperature increased, the grain size and porosity of coating gradually increased. Significant cracks were observed and W was found in the Ni-W coating annealed at 1 000 ℃.The micro-hardness of annealed Ni-W coatings were much higher than that of as-deposited coating, while an adverse corrosion performance was observed for the annealed Ni-W coatings. The corrosion resistance became worse with the increasing annealing temperature. The coating annealed at 500 ℃ showed a biggest micro-hardness value and a fairly acceptable corrosion resistance.
