Evaluation of the real contact area in three-body dry friction by micro-thermal analysis [PDF]
, 2009 Many tribological properties and wear mechanisms occurring on the micro-and nanoscale are strongly controlled by the so-called real contact area (Ar) which is a small fraction of the nominal or apparent contact area (Aa). The determination of Ar is often

Tribological properties of surfaces [PDF]
Thin Solid Films, 1978 The real area of contact between two solid surfaces is only a small portion of the apparent area. Deformation of these areas can result in solid state contact through surface films. For clean solid to solid contact strong adhesive bonding occurs across the interface.
