Most shrink fit joints, couplings and fasteners of machine components are generally made up of AISI 1040 steel. These components are subjected to the fretting wear due to vibrations induced from machine operation. Fretting wear test on AISI 1040 steel is performed at 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 reveal that normal load has significant effect on fretting wear performance of AISI 1040 alloy. Optical micrograph obtained from optical microscope shows that with increase in normal load transition of gross sliding to partial sliding takes place.
