摘要：In this paper, Ni-TiN composite coatings were prepared by ultrasonic-magneticelectrodeposition. The optimum parameters were achieved by experiments and analysis. The structure of Ni-TiN coatings was observed using HRTEM. And the wear resistance was tested by the grinding machine. The results illuminated that the optimum technical parameters prepared Ni-TiN coatings are TiN particle concentration 4g/L, ultrasonic power 200W, magnetic intensity 0.6T, current density 5A/dm2, temperature of the electrolyte 50°C, pH 4.5. The HRTEM showed that the diameter of Ni grains and TiN particle in Ni-TiN coatings were about 60nm and less than 40nm, respectively. © (2012) Trans Tech Publications, Switzerland.
