“…Severe wear is usually accompanied by removal of a large amount of material, where the surface state changes too fast to distinguish the tribochemical and tribo-mechanical behavior. In order to investigate the tribochemical behavior, the severe wear damage over long cycles to needs be avoided [15]. Therefore, friction tests at low load of 0.1 and 1 N were used to characterize the tribochemical behavior.…”

“…In addition, the surface was contaminated with carbon that allowed formation of MgCO 3 . When the fresh metal surface is exposed by friction, the metal oxide is formed simultaneously [15], resulting in subsequent formation of MgO formed during sliding friction. The oxide layer, consisting of Mg(OH) 2 •H 2 O, MgCO 3 and MgO, had a solid lubricating effect and protected the worn surface.…”

“…After wear due to sliding friction at 0.1 N, tribochemical reactions occurred and the surface composition changed, with some of Mg(OH) 2 •H 2 O forming, as shown in Figure 12. In this case, H 2 O atoms can be easily attached to the tribofilm on the worn surface [15]; some of the Mg(OH) 2 was hydrated to form the Mg(OH) 2 •H 2 O. When Mg contacts with H 2 O, MgO formed firstly, and then changed to Mg(OH) 2 spontaneously depositing on the metal surface.…”

Reciprocating sliding friction tests were conducted on pure magnesium using a UMT-II tester. The tribo-chemical behavior was characterized using X-ray photoelectron spectroscopy (XPS) and electron probe micro-analyzer (EPMA), which showed that the tribo-chemical behavior of pure magnesium was due to a tribo-oxidation reaction. At room temperature, the debris layer on the worn surface contained Mg(OH)2, MgO, and MgCO3. According to the reciprocating sliding friction mechanism, the decomposition of MgCO3 into MgO should occur. XPS results revealed that the surface oxide layer, containing Mg(OH)2, and MgO, acted as a third layer to protect the surface. Apparently, Mg(OH)2·nH2O was the main tribo-chemical product of pure magnesium under sliding friction.

“…From Figure 13(a) and (b), the O 1s XPS spectrum is decomposed into the bonding of C–O, O–H, and O 2− . 19,20 The peaks of the three oxygen states are at 532.8 ± 0.3 eV, 531.8 ± 0.3 eV and 530.3 ± 0.3 eV, respectively. In order to compare the ratios of O in the metal oxide and the absorbed O 2− (C–O and O–H bonding) in the fretting zone, different torques and cycles are calculated and presented in Table 4.…”

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+.

“…9b) [18,[31][32]. As shown in Fig.9d, the main peak of Fe 2p observed at 710.97 eV may be assigned to the Fe 2p 3/2 accompanied with a smaller peak of Fe metal at 707.10 eV, and the separation energy between the main Fe 2p 3/2 peak and its satellite peak is 9.0 eV, demonstrating the existence of Fe 2 O 3 [33]. These results suggest that H and OH combined with the carbon atom in the graphene layer.…”

A multiple-layer graphene was prepared on steel surface to reduce friction and wear. A graphene-containing ethanol solution was dripped on the steel surface, and several layers of graphene flakes were deposited on the surface after ethanol evaporated. Tribological performance of graphene-contained surface (GCS) was induced by reciprocating ball against plate contact in different RH (0% (dry nitrogen), 30%, 60%, and 90%). Morphology and wear scar were analyzed by OM, 2D profile, SEM, Raman spectroscopy, and XPS. Results show that GCS can substantially reduce the wear and coefficient of friction (COF) in 60% relative humidity (RH). Low COF occurs due to graphene layer providing a small shear stress on the friction interface. Meanwhile, conditions of high RH and textured surface could make the low COF persist for a longer time. High moisture content can stabilize and protect the graphene C-network from damage due to water dissociative chemisorption with carbon dangling bonds, and the textured surface was attributed to release graphene layer stored in the dimple.
