Abstract: Electrodeposition technology is a kind of convenient, efficient, low cost method for preparing metal matrix nanocoatings, and the plating parameters directly determine the microstructure and properties of the coating. In order to investigate the influence of plating parameters on surface morphology, microstructure, mechanical properties and wear resistance of metal matrix nanocoatings, Ni-TiN nanocoatings were successfully prepared by using pulse electrodeposition method in this paper, and the influence of plating parameters on microstructure, microhardness and properties of the coating was investigated with the use of transmission electron microscopy (TEM), atomic force microscopy (AFM), X-ray diffraction (XRD) and friction wear testing machine. The results showed that the Ni-TiN nanocoating obtained at 4 A/dm2 current density exhibited an optimum microhardness and TiN content values of 984.7HV and 8.69 wt%, respectively. Ni-TiN nanocoatings prepared at different pulse frequencies exhibited fcc structure in different directions. The average grain diameters of Ni and TiN in the nanocoating prepared at 200 Hz were 87.2 nm and 34.6 nm, respectively. The nanocoating prepared at 20% duty cycle showed an optimum microhardness and average wear of 980HV and 7.56 mg/mm2, respectively.
