	The present study reports on improvements of the tribomechanical properties of commercial aluminum especially wear and hardness by nitrogen implantation. The implantation process has been carried out at doses 5×1016, 1×1017 and 6×1017ions/cm2 and energy 180keV. The tribological tests for the friction coefficients and wear were made on a pin-on-disk tribotester with the load 0.98N. XRD analyses were performed to obtain a characterization of the surface of the implanted sample. The implanted specimens were also annealed at 400°C in addition to the non-implanted specimen for referring. The hardness showed remarkably significant improvement at the higher dose, 6×1017ions/cm2. Before annealing, the friction coefficients of the implanted samples were nearly unchanged. After annealing at 400°C, these coefficients exhibited a relative decrease from about 0.33–0.22 at dose 1×1017ions/cm2. On the other hand, the wear rates of the implanted samples and the countersample exhibited a great decrease after annealing the samples of aluminum at 400°C whereas the wear decreased from about 38 to 3μm2 for the samples at the higher dose, 6×1017ions/cm2.
