The influence of anisotropically shaped textures on the behaviour of sliding friction and sensitivity to sliding direction was evaluated through experimental methods, and performance of textured surfaces was carefully compared with non-textured surfaces. In particular: Fig. 1. Parameter symbols in design. Fig. 2. Triangular sloped (TS) dimple topography measurements. Fig. 3. Triangular sloped (TS) dimple topography with cross-section profiles. Fig. 4. Triangular sloped (TS) bottom dimple samples' wear scar topography (a) TS1 (b) TS2 (c) TS3. Fig. 5. Stribeck curves for TS1, TS2 and TS3 samples. Fig. 6. Friction force measurements versus time of triangular slope dimples (a) TS1 (b) TS2 (c) TS3. Fig.7. Real contact length between roller and surface when roller is sliding above a dimple array. Fig.8. Converging and diverging friction variation with trend line subtracted (under 350 N, 2 Hz) for triangular sloped (TS) bottom dimpled samples TS1, TS2 and TS3. Table.1. Parameters of triangular sloped (TS) bottom dimple designs. Table.2. Measurements of triangular sloped (TS) bottom dimple samples' wear scar.
