摘要	The relationship between structure and mechanical, tribological and corrosion properties of coatings is inves-tigated by adjusting the annealing time (750 degrees C for 1-10 h). Results exhibit that the coatings mainly consist of Ni (Mo) and Mo2C, and MoC is formed after long time annealing (>= 4 h). The hardness of coatings decreases from 9.3 GPa to 5.9 GPa with the extension of annealing time, and the inversion relationship between strength and toughness (0.19-0.17) is observed owing to the decline of elastic recovery. The highest wear rate of coatings is about 13.6 x 10-6 mm3 N-1 m-1, and most of them under the applied load of 1.96 N and 3.92 N are in the range of 2.1-6.3 x 10-6 mm3 N-1 m-1. Meanwhile, the wear resistance of coatings annealed for 1-4 h is better than those annealed for longer time (6-10 h), and the change of it is proportional to the hardness and elasticity re-covery. In addition, the corrosion resistance of coatings in 3.5 wt% NaCl solution decreases with annealing time due to the grain growth, the uneven distribution of composition and the increase of porosity.
