“…As fretting typically features a much smaller amplitude compared with the contact area width (Figure 1), most of the contact area keeps in contact as such, meaning some wear debris remains entrapped [5]. The retained debris undergoes repeated crushing, which affects the contact pressure distribution and changes the development of the fretting wear scar [6,7]. In sliding tests, though some debris is inevitably entrapped at the contact zone, most debris is expelled, leading to more direct metallic contact [8].…”

Objectives: The aim of the present work was to comparatively investigate the generation and characteristics of fretting and sliding wear debris produced by CuNiAl against 42CrMo4. Methods: Tribological tests were conducted employing a self-developed tribometer. Most experimental conditions were set the same except for the amplitudes and number of cycles. Morphological, chemical, microstructural and dimensional features of the worn area and debris were investigated using optical microscope (OM), X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) and a laser particle sizer. Outcomes: Not only wear scar profiles but also the wear debris color, distribution and generated amount under fretting and sliding wear modes were quite different, which can be attributed to the significant difference in wear mechanisms. Particle size analysis indicates that the fretting debris has a smaller size distribution range; the biggest detected fretting and sliding wear debris sizes were 141 μm and 355 μm, respectively. Both fretting and sliding debris are mainly composed of copper and its oxides, but the former shows a higher oxidation degree.

“…formation of cracks in the oxide scale on the fretted surface is a key issue that determines if delamination happens. The theoretical explanation for delamination [10,57,58] is that the dislocations pile up under the fretted surface, which leads to void coalescence and cracks parallel to the surface form. In the propagation process, the crack can shear to the surface when a weak position is reached, which results in the formation of thin wear sheets.…”

“…This was investigated over a wide range of temperatures from 24 • C to 85 • C [21]. Other experiments performed on nickel-based alloys also show that the formation of a layer of oxide during high-temperature fretting wear acts as a protective third body between the contacting surfaces [27]. Nassar et al investigated the effect of cold temperatures on metallic alloys reinforced with ceramic particles.…”

Investigation of the Effect of Temperature on the Wear Rate and Airborne Noise in Sliding Wear

When friction processes occur, wear is generated. The generation of wear also leads to airborne noise. There have been many research studies on wear and its correlation with airborne noise, but most research has focused on experimental aspects, and theoretical models are rare. Furthermore, analytical models do not fully account for the wear and airborne noise generation, especially at an asperitical level. One model was developed that gave a reasonable quantification for the relationship between wear and airborne noise generation at an asperitical level under room temperature. In this paper, the accuracy of the model is assessed at higher temperatures. Two materials were set up on a tribometer (aluminium and iron) at 300 RPM. The samples were tested at two different temperatures (40 and 60 degrees) and two different loads were applied (10 N and 20 N). The model computed the predicted wear and sound pressure, and it was compared with the experimental results. The errors are larger for the wear than when the model was validated at room temperature. However, the increase in the error for the sound pressure was smaller at higher temperatures (approximately 20–30%). This is due to the assumptions that were made in the initial model, which are exacerbated when higher temperatures are applied. For example, flash temperatures were neglected in the original model. However, when initial heat is applied, the effects of flash temperatures could be more significant than when no heat is applied. Further refinements could improve the accuracy of the model to increase its validity in a wider temperature range.
