Figure 12: (a) Average friction coefficients of tested samples: unimplanted (Top) and N-implanted (Bottom). A = 2e17 ions/cm2 at 100 kV, B = 1e17 ions/cm2 at 100 kV, C = 5e16 ions/cm2 at 100 kV, D = 2e17 ions/cm2 at 50 kV, E = 2e17 ions/cm2 at 100 kV at 100% Red, F = 2e17 ions/cm2 at 50 kV; 100% red, G = 2e17 ions/cm2; 100 kV; heat treat, and H = 2e17 ions/cm2 at 100 kV; 100% red; heat treat. (b) Example friction traces for different samples.
