Damage of aluminium alloy under contact loading is detected in different cases independent of contact configuration and operating conditions. An investigation of two industrial cases is proposed to describe how it is possible to study the material degradation under friction. The experimental simulation of aluminium damage in laboratory conditions is carried out. Two contact configurations are studied in order to reproduce the industrial damage of aluminium alloys. Varying experimental conditions relative to a specific contact body for each test have demonstrated a realistic correlation between damage, test configuration and material properties. Independent of the tribological system, plastic deformation seems to be the major parameter controlling the wear of aluminium alloy under friction in the studied cases.

The purpose of this paper is to study the correlation between abrasive wear resistance, contact configuration and grain size of aluminium alloy.

Different aluminium alloy with different grain size has been tested using a scratch test. Comparison between scratch parameters, especially scratch depth and grain size aluminium alloy, has been made. Two indenters were used: conical and spherical indenter.

Correlation between grain size of aluminium alloy, configuration contact and abrasive wear resistance has been discussed. This study can be useful for choosing material which can provide better abrasive wear resistance.

This study can be a reference both practically and academically. A similar study has been made in order to investigate the effect of hardness in abrasive wear resistance. However, the importance of microstructure and especially the grain size of aluminium alloy have been taken into account.
