Most of the shrink fit joints, couplings, and fasteners of machine components are generally made up of AISI 1040 steel. These components are subjected to fretting wear due to vibrations induced by machine operation. Fretting wear test on AISI 1040 steel is performed with different normal loads in ambient condition using Rtec MFT 5000 tribometer. The effect of different normal loads on coefficient of friction, slip regime and wear profile are analyzed. The result reveals that normal load has a significant effect on fretting wear performance of AISI 1040 alloy. Optical micrograph obtained from optical microscope shows that with an increase in normal load, wear depth increases and transition of slip regime from gross slip to partial slip occurs.
