Effect of aluminium grain size on scratch resistance for spherical and conical indenter

Abstract

PurposeThe purpose of this paper is to study the correlation between abrasive wear resistance, contact configuration and grain size of aluminium alloy.Design/methodology/approachDifferent 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.FindingsCorrelation 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.Originality/valueThis 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.
