The hard anodizing process of aluminium alloys promotes the growth of a highly ordered nanoporous alumina (Al₂O₃) layer, whose final width and properties are significantly influenced by the process parameters. Anodizing is frequently used to enhance corrosion resistance, surface durability and aesthetic properties of the surrounding aluminium substrate. For tribological performance, laboratory scale tests are the common engineering approach to give insight into wear and coefficient of friction characteristics. More specifically, wear maps are a useful guide to understand the wear properties of a material in a spectrum of operating conditions and to establish the critical operating limits [1,2]. A better approach to represent wear rate data was also offered using pressure instead of load, to explain the non-steady-state progression of wear rate [3,4]. This work concerns the tribological characterization of an EN AW-6082 wrought aluminium alloy treated with an innovative hard anodizing treatment in which the anodic oxide layer was sealed by Ag⁺ ions (G.H.A.® technology). Dry wear tests were conducted in ball-on-disk configuration on a reciprocating pin-on-disk tribometer. The EN AW-6082 aluminium alloy disks were superficially treated by G.H.A.® and sealed by a standard hydrothermal process. The influence of a polishing process on the wear properties of the above-described treatment was also evaluated. Balls made of 100Cr6 steel with a diameter equal to 10 mm were used as counterbody. The coefficient of friction (COF) and overall system wear were constantly measured during tribological tests. In order to build quantitative wear maps, samples were tested at different values of sliding speed (m/s) and normal load (N) on a total sliding distance of 200 m. The evolution of specific wear rate (WR) was also taken into account: tribological tests were interrupted at regular steps (after 50, 100 and 150 m) to evaluate wear scars and volume loss. To calculate WR, wear scars were analyzed using a stereomicroscope (for ball wear scars) and a 3-D optical non-contact profilometer (for disks). Worn surfaces were also analyzed through scanning electron microscopy (SEM) to identify the wear mechanism at different test conditions. The results suggest that COF was independent of test conditions, while different shapes of wear maps were built for polished and non-polished surfaces.
