The Ni-TiO2 nano-coatings were prepared on the AISI 1022 carbon steel (CS) surface using the pulse electrodeposition method. The surface structure of CS was considerably reformed owing to the titanium particles presence. The electroplating is widely used as a protection of the material surface to expand the life of vehicle components. The parameters of pulse frequency (PF - Hz), current density (CD - A/cm2) and duty cycle (DC - %) are combined into the RSM three factors and three level arrays to find the effect of the wear rate coating parameters. The Ni-TiO2 nano-particles deposited surface structure and wear of the surface were examined by field emission scanning electron microscopy (FESEM) and wear test was conducted by pin on disc wear tester. The experimental result revealed a lower specimen wear rate of the parameter is the frequency: 20 Hz, current density: 0.2 A/cm2 and duty cycle: 30 %. The ANOVA result revealed the pulse frequency and current density quadratic term are the most essential factor contributing 28.48, 29.95 % impact on wear resistance.
