Fretting Fatigue Behavior of Aluminum Alloy

Abstract

In this study, the fretting fatigue behavior of aluminum alloy was studied by carrying out experimental fretting fatigue tests and fretting wear test using Al–Si–Mg (2024-T6) alloy. For fretting wear test, both the pin and plate are made of Al–Si–Mg alloy. In fretting fatigue test, both the specimens and contact pads (bridge type) are made of Al–Si–Mg alloy. Fretting wear tests were conducted to get basic friction properties. Fretting fatigue tests were carried out at various contact pressures (100, 150 and 200 MPa). Finite element analysis was carried out to obtain the stresses at the contact, i.e., tangential stress and compressive stress. The relation between tangential stress, compressive stress, and fretting fatigue lives has been plotted for the Al–Si–Mg alloy. Based on the plot, the fretting fatigue strength prediction of Al–Si–Mg alloy was discussed. © 2020, Springer Nature Singapore Pte Ltd.
