“…In addition, if the hardness of 390 HV 0.2 kg is considered as the threshold value (Wang et al, 2015), the effective hardened case depth is approximately 230 mm. Iron nitrides Fe 4 N and Fe 2$3 N appeared on the surface after plasma nitriding, which was responsible for the significant improvement of the hardness and enhanced the anti-wear and anti-seizure ability of the steel (Wang et al, 2016).…”

“…The process is quite similar to the ball milling process in the powder metallurgy field, where amorphous structure is easily formed (Yang et al, 2014). (Wang et al, 2016), so there are no peaks of theirs in the XRD patterns in Figure 6(c). In summary, the wear debris did include some amorphous structure, while the crystal phases were combination of iron oxides and chromium oxide rather than exclusive iron oxides as most other researches have reported (Rynio et al, 2014).…”

“…Under the line contact condition, the wear scar is shaped as a V groove, which is deep in the center and shallow around the edges. Thus, the wear debris could not The left debris was repeatedly ground, rolled, oxidized and even became amorphous on the interface (Wang et al, 2016). The process is quite similar to the ball milling process in the powder metallurgy field, where amorphous structure is easily formed (Yang et al, 2014).…”

Purpose Fretting wear exists widely in the field of matching mechanical parts whereas previous research studies mostly focus on the point contact through a ball-plate tribometer. This paper aims to study the influence of wear debris on the fretting wear characteristics of the nitrided medium carbon steel under line contact condition at elevated temperature. Design/methodology/approach Fretting wear behavior of the nitrided medium carbon steel was experimentally investigated under line contact condition at elevated temperature and different normal loads without lubrication. Wear loss, worn surface and wear debris were studied to analyze the wear mechanism of nitrided steel. Findings The results showed that surface hardness of the medium carbon steel was notably improved because of the generation of a 230 µm nitrided case. Wear loss increased with the normal load, which was associated with the damage of a thin solid film formed by the wear debris, consisting of iron oxides and chromium oxide rather than only iron or iron oxides. The wear debris became partially amorphous and spherical because it was trapped within the contact interface and was ground, rolled, oxidized under line contact conditions. The spherical wear debris acted as a third body and formed a lubricating film between the contact faces. This lubricating film helped to stabilize the friction coefficient and reduced the wear rate, which further caused the acceleration of wear volume to gradually decrease. The wear mechanisms of the nitrided steel were oxidation wear, abrasive wear and fatigue spalling of the oxide layer. Originality/value The findings are helpful to understand the fretting wear behavior of the friction pair under line contact and enrich the fretting tribology theory.

Plasma sprayed ceramic coatings have been widely used in friction and wear protection of mechanical parts. In this paper, the nanostructured Al2O3-13 wt.% TiO2 coatings were prepared by high-efficiency supersonic plasma spraying (HESP) and atmospheric plasma spraying (APS) respectively. The surface and section morphology of the coatings were observed by scanning electron microscopy (SEM). The phase composition of the coatings was analyzed by X-ray diffraction (XRD). The dry sliding friction properties of the coatings were tested on UMT-3 friction and wear testing machine. The results show that after plasma spraying, a large amount of γ-Al2O3 phase appears, while TiO2 phase almost disappears in the coatings; compared with APS, the coatings sprayed by HESP have fewer defects and better coating quality; under dry friction condition, the steady-state friction coefficient of the coatings sprayed by HESP and APS all decreases with the increase of load, and the wear volume all increases with the increase of load. When the load is more than 40 N, wear volume of the coatings sprayed by APS is basically twice that of HESP; the wear mechanism of the coatings sprayed by HESP is the laminar cracking, peeling off and the adhesive wear.
