... approach, while open squares are numerical results obtained from GFMD simulations. Fig. 5 Reduced pull-off force L ~ po as a function of shape index n . The effective thickness is fixed to h 0 = 8 × 10 − 4 R c and the applied voltage is set...

... of cycles in the tribological tests. It is not influenced by pull-off forces. However, the high pull-off force of the reactively sputtered film makes the friction coefficient sensitive to capillary forces. 4. No transfer of counteracting body material is observed on the wear tracks. 5. The amorphous...

... values of H ′ , from which the critical H are then determined. Results are shown in Fig. 6 , where the critical H ′ are plotted versus χ . The dimensionless pull-off force, F p ′ , as a function of χ − 2 ∕ 3 for Φ = 0...
