The Mechanism of Fretting Wear
Journal of Lubrication Technology, 1973An experimental study has been carried out of wear and energy dissipation of contacts vibrated at high frequencies. The amplitude, number of cycles, and degree of lubrication were varied. In addition, an analysis was carried out of quantitative fretting wear results described in the literature.

Fretting wear of sintered alumina
Wear, 1986Abstract Cylinders of alumina, carbon steel, glass and tungsten carbide have been fretted against rectangular specimens of sintered alumina. The damage caused has been assessed by four-point loading bend tests. Coefficients of friction of the contacting surfaces have been measured.

The “velocity accommodation” concept was introduced recently in Tribology. Velocity accommodation can occur in five sites: the two first bodies (FB1, 2), identified as S1or5, the two screens which separate the bulk of the third-body from the first-bodies (TB51, 2), identified as S2or4, the bulk of the third-body (TBb) identified as S3 ...

Abstract Fretting is the small-amplitude oscillatory movement that can occur between contacting surfaces, which are nominally at rest. This article discusses fretting wear in mechanical components and the mechanisms of fretting wear. It describes the role of fretting conditions, such as fretting duration, slip amplitude, normal load ...

Abstract The tribological behaviour of engineering ceramic materials can be influenced by several tribosystem parameters. Friction and wear properties of different types of ceramics (silicon nitride, silicon carbide, alumina and zirconia) are evaluated for the case of oscillating sliding motion at room temperature. The influence of such parameters as:

Semi analytical fretting wear simulation including wear debris
Tribology International, 2017Many numerical models are proposed in the literature using finite element and finite discrete element methods to study fretting wear, barely including the effect of wear debris. These models being computationally expensive, simulating large number of fretting wear cycles is not practically feasible.

Fretting fatigue strength estimation considering the fretting wear process
Tribology International, 2006Abstract In fretting fatigue process the wear of contact surfaces near contact edges occur in accordance with the reciprocal micro-slippages on these contact surfaces. These fretting wear change the contact pressure near the contact edges. To estimate the fretting fatigue strength and life it is indispensable to analyze the accurate contact pressure ...

Fretting Wear Mechanisms and Their Effects on Fretting Fatigue
Journal of Tribology, 1988Fretting wear and fretting fatigue are governed by the rate of formation of materials (third-bodies) between the initial contact surfaces. Furthermore, the third-bodies must be maintained within the contact. The issue of the race between third-body formation and subsurface damage conditions the effect of fretting on fatigue.

Investigation of fretting wear in journal bearings
Industrial Lubrication and Tribology, 2016Purpose Fretting wear takes place when two contacting solid surfaces are subjected to relatively small amplitude oscillatory motion in the order of a few microns. The purpose of this paper is the design and manufacture of a fretting wear test rig that can analyze fretting wear on journal bearings.

A new fretting wear test apparatus
Journal of Physics E: Scientific Instruments, 1988A new fretting wear test rig was designed. The fretting contact consists of a sphere-on-plate arrangement. The temperature in a test can be set up to 1200 degrees C (specimen temperature 800 degrees C) and the normal load adjusted to between 130 and 600 N. The frequency can be between 1 and 60 Hz.
