Single Metal Particles Nanoscale Friction and Wear

The sliding behavior between single pairs of gold and carbonyl iron particles with diameters of 5–10 μm were studied by Friction Force Microscopy. Normal load between the particles during friction was varied in the range of 0–3 μN. For the gold particles, two different wear regimes could be observed. At lower loads, only mild wear was observed, probably due to the typical organic contamination layer. At higher loads, strong wear of the gold surface was observed due to direct metallic contact. For the sliding between CIP, only mild wear was observed possibly due to the protective oxide layers which prevented the formaton of direct metallic contacts. The evolution of friction between the sliding particles was quantitively examined by use of inverse cumulative distribution functions, which allowed to correlate the increase in friction with the change in surface topography. During mild wear, the friction in the sliding area was found to change with the local radius of curvature and to increase nearly linear with increasing load. Within this regime, the dependence of friction F on load W followed the relation The values μ and obtained from different combinations of particles were and for gold and and for iron respectively.
