Study on tribo-chemical and fatigue behavior of 316L austenitic stainless steel in torsional fretting fatigue

Abstract

Fretting fatigue is a complex tribological phenomenon that can cause premature failure of connected components. Combining with the effects of tribological and fatigue, the components have premature fracture, which ultimately leads to disastrous consequences. In this work, the fretting fatigue tests of 316L austenitic stainless steel have been carried out with same normal load and varied torsional torques. The results indicate that the fretting fatigue life significantly depends on the torque amplitude, wear degree of the fretting damage zone, hysteresis loops and energy dissipation. A physical model for fretting crack initiation and propagation is created to explain the failure process of torsional fretting fatigue. The results from X-ray photoelectron spectroscopy analysis show that the extent of oxidation in the fretting damage zone is affected by the amplitude of relative displacement. The tribo-chemical reaction in the slip regime is more activated than that in partial slip regime. It can lead to more severe wear in the slip regime. The wear debris of the fretting damage zone is composed of metallic Fe, Fe2+ and Fe3+.

A review of advances in tribology in 2020–2021

“…Vast differences were observed in the effects of oxygen on the wear rates of the two materials. Xu et al [295] studied on tribochemical and fatigue behavior of 316L stainless steel by using a torsional LFV100-T500-HH servo fatigue tester. By XPS analysis, they found that the extent of oxidation in the fretting damage zone was affected by the amplitude of relative displacement.…”

Failure Mechanism Research on Bending Fretting Fatigue of 6061-T6 Aluminum Alloy by Experiment and Finite Element Method

“…According to different types of fatigue loads, there are three types of fretting fatigue: fretting fatigue of tension-compression, torsion, and bending [8]. Most of the existing studies have focused on the fretting fatigue of tension-compression and torsion, while studies are limited on the fretting fatigue of bending [9][10][11][12]. Ebaraa et al studied the bending fretting fatigue behaviors of Ti-6Al-4V [13].…”

Numerical analysis of fretting wear in lateral contact of sphere/sphere

“…Leonard et al 15 developed the finite discrete element model (FDME), which accurately predicted the wear amount obtained in the experimental measurement through the energy dissipation method, and the changes in the energy dissipation rate and wear amount were analyzed. Xu et al 16 performed the fretting fatigue experiment on 316L austenitic stainless steel under the same normal load and different torques. The results show that the torque amplitude, wear degree, and energy dissipation significantly affected the fretting fatigue life.…”
