Study on Friction and Wear Behavior of Inconel 625 Superalloy during Hot Extrusion

Figure 3

Evolution of friction coefficients between Inconel 625 disk and Si₃N₄ or GCr15 balls at a temperature of 250°C and a sliding rate of 525 mm/s. The macroscopic morphology of the wear mark by (a) GCr15 grinding and (b) Si₃N₄ grinding.
