“…As fretting is associated with very small displacement amplitudes, debris that is entrapped in the contact plays a critical role in the subsequent fretting wear behaviour; Iwabuchi [27] and Colombie & Berthier [28] argued that the role of debris within a fretting contact can either be protective, reducing wear, or act as an abrasive and increase wear. Protection by the retention of debris within the contact typically results from the debris preventing the first bodies (from which the debris is created) from interacting [29,30]; the severe adhesive wear associated with metalmetal contact is reduced, and the debris layer may also shear easily and thus accommodate the lateral motion.…”

Fretting wear mapping: the influence of contact geometry and frequency on debris formation and ejection for a steel-on-steel pair

This paper examines the influence of contact geometry and oscillation frequency in a steel cylinder-on-steel flat fretting contact, with contact geometry being varied via the cylinder radius. Fretting frequency did not significantly impact the wear behaviour for more-conforming contacts, but did so for less-conforming contacts where, at high frequency, the wear rate is approximately 50% of that observed for low-frequency fretting. It is proposed that frequency and contact conformity fundamentally control wear behaviour through influence of both the debris type and the retention or ejection of that debris from the contact. The debris type (either oxide or metallic) is influenced by fretting frequency (which controls the interval between asperity contacts) and by contact conformity (which controls the distance that oxygen has to travel to fully penetrate the contact). Debris retention within the contact is promoted by higher fretting frequencies (the associated higher contact temperature promotes debris agglomeration and sintering in the contact) and by higher contact conformity (which acts as a physical barrier to debris egress). Maps are presented which categorize the observed behaviour and outline a phenomenological framework by which the basic physical processes which influence fretting behaviour can be understood.

“…Previous studies [10][11][12][13] indicate that the presence of the oxide debris in the fretting contact can significantly influence the wear behaviour, with Godet [10] proposing the concept of the debris acting as the third body between the wearing surfaces which prevents direct contact between the primary surfaces. Iwabuchi et al [14] studied the role of the debris by artificially supplying oxide particles into the contact (as opposed to the oxides being formed by the wear process itself) and concluded that the formation of a stable and compacted oxide layer will result in a reduction in wear, but if such a layer does not develop, the wear rate will be increased by the oxide particles acting as an abrasive.…”

In further experiments to understand the role of the oxide in fretting, Colombie et al [12] performed tests which were periodically interrupted to allow removal of the debris from the contact; these tests provided further evidence regarding the significance of the debris bed in determining fretting behaviour.…”

The Role of Temperature and Frequency on Fretting Wear of a Like-on-Like Stainless Steel Contact

The influences of environmental temperature and fretting frequency on the mechanisms and rates of wear in a like-on-like 304 stainless steel contact were examined and mainly attributed to changes in the mechanical response of the bulk material and to changes in the behaviour of the oxide debris formed in the fretting process. At low temperatures, wear proceeds by continual oxide formation and egress from the contact, whilst at high temperatures, the rate of wear is much reduced, associated with the development of oxide formed into a protective bed within the contact. The temperature at which the change between these two behaviours took place was dependent upon the fretting frequency, with evidence that, at this transition temperature, changes in behaviour can occur as the fretting test proceeds under a fixed set of conditions. An interaction diagram has been developed which provides a coherent framework by which the complex effects of these two parameters can be rationalised in terms of widely accepted physical principles.

Compared with ceramic materials, wear debris is looser and can also respond kinematically to the velocity mismatch, and accordingly, causes less damage than that occasioned by locked asperities of the mated material with identical hardness 28 .…”

The Al 2 O 3 -TiO 2 coating for turbine blades is being used since long. During the last decades, a large number of papers have been published, but work on property assessment of Al 2 O 3 -TiO 2 coating on rotating component from tribological point of view is very less. This paper assesses the wear behaviour of Al 2 O 3 -TiO 2 coating on inconel 601. The Al 2 O 3 -TiO 2 coating on inconel 601 is deposited by plasma spray process. The SEM results show that above 300 o C, the friction coefficient decreases due to softening of coating material. The wear rate increases with increase in temperature. The coating showed brittle fracture at higher temperature. Other test results have shown the drastic changes in property due to load and temperature.
