It was found that the tribological application of nanocomposite coatings was strongly dependent on their compositional, morphological, and structural characteristics. According to the literature, these properties are directly related to the preparation method and deposition conditions such as current density, substrate, pH, ion concentration, size and quantity of nano-particles, and agitation frequency. Thus, the optimi‐ zation of the parametric setting is of critical importance to assess the wear resistance of the coating.

The results demonstrated that Taguchi DOEs can be effectively used to optimize the electro‐ deposition process; however, due to material limitations the experiment was restricted to the use of only two samples per condition. Increasing the temperature and particle concentration caused a reduction in the wear rate of the coating. The results also show that increasing temperature to 50°C caused a reduction in the wear rate of the coatings deposited. Stir rate is the parameter having the least effect on the wear rate of the coatings.

The combination of optimum bonding parameters within the experimental level ranges is found to be a temperature of 50°C, particle concentration 30 vol.%, stir rate 820 rpm, and pH 4.45. Within the experimental level ranges, the most significant influencing parameter is particle concentration, which accounts for 51.68% of the total effect, followed by temperature (32.41), bath pH, and stir rate (12.27% and 3.64%, respectively).
