The goal of this study was to describe the results of a Taguchi analysis of the tribological behaviour of a matrix of Al7075 alloy reinforced with 0%, 1%, 2%, and 3% by weight nanoscale titanium dioxide (TiO₂) particles. Wear patterns were studied using a three-dimensional optical microscope. Abrasive and adhesive wear may be seen in images obtained from the optical microscope, and both of these types of wear contributed to the surface’s degeneration. Sliding velocities, distances, loads, and percentages of mass were determined using the Taguchi model. The proportion of nano TiO₂ in the material had the greatest impact on the coefficient of friction (38.54%), whereas the normal load had the greatest impact on the wear rate (35.61%).
