Multitechnique Studies on Fretting Fatigue: Influence of Surface Treatment.

Abstract

In the experimental program a specially constructed apparatus was used to simulate conditions at the faying surfaces in a structural joint. Fretting fatigue tests were carried out on 34 Chromium Nickel Molybdenum 6/100Cr6 steels using stress ratios from the range of finite endurance. Two methods of surface treatments are used: polishing and shaping. Two directions of each surface treatment are considered: parallel and perpendicular to the sliding direction. The results are compared to baseline tests on the same material without fretting and are discussed in terms of the effect of surface roughness and normal force. Keywords: fatigue cracks, contact pressure, contact resistance, contact temperature, normal force, friction force, linear wear rate, shear stress, crack detection, magnetic induction.
