Abstract—Aluminium alloys are very attractive compared to other materials like steels, particularly for their
mechanical properties. Despite of having a relatively low density (2.7 g/cm^3 ascompared to ±
7.9 g/cm^3 of steel), they also possess high ductility (even at roomtemperature), high electrical
and thermal conductivity and resistance to corrosion.However, aluminium by itself exhibits poor
tribological properties and their usage, for example in automotive applications, has been limited
by their inferiorstrength, rigidity and wear resistance, compared with ferrous alloys.With respect
to friction and wear behaviour, it has been well understood that the tribological behaviour of
aluminium alloys is strongly influenced by the mechanical, physical and chemical properties of
the near-surface materials.Intimate contact between ductile materials in particular, normally
involved transferred materials, which may result in theformation of a mechanically mixed layer
