“…Furthermore, the oxide layers were justified by the EDS patterns shown in Figure 10e. These results, combined with those in our previous study [16], showed that the oxide layers formed by the fretting wear process were composed of TiO2, SiO2, Fe2O3, and Fe3O4 debris transferred from the counterpart. It was noted that the composition of element O was significantly increased due to the pre-oxidation treatment and the transformation from the counterfaces.…”

“…The Ti 3 SiC 2 coatings were deposited by an air plasma spray (APS) system on grit-blasted (3 bar, corundum EKF 30) nickel-aluminum bronze substrates with a dimension of 30 × 50 × 7 mm 3 . Commercial grade Ti 3 SiC 2 powders (purity ≥ 98.0 wt %) with a particle size of 40 µm served as starting materials and details of the components have been reported in our recent work [16]. The plasma spray parameters were listed as follows: the input power supplied to the gun was 33 kW, the primary gas (Ar) flow rate was 33 standard liters per minute (slpm), the secondary gas (H 2 ) flow rate was 2 slpm, and the spray distance was 85 mm.…”

“…The synthesized Ti 3 SiC 2 bulks restrict the potential for tribological applications in engineering components, whereas plasma spraying with a high spray temperature and a prominent deposition rate provides an efficient way to achieve these wear-resistant coatings of the MAX phase. The plasma-sprayed Ti 3 SiC 2 coatings exhibited improved fretting wear properties because of the healed cracks by selective oxidation of Ti 3 SiC 2 and the lubrication of tribo-induced oxides [16]. However, the friction coefficient maintained at a relatively higher level compared with that in high temperature or high sliding speed.…”

In this study, efforts were made to oxidize the Ti3SiC2 coating surface to improve its wear resistance by producing oxide layers and healing microcracks that initiated from the thermal sprayed process. Tribological behaviors of the thermal oxidation-treated Ti3SiC2 coatings subjected to various temperatures (200, 300, and 400 °C) and durations (1, 3, and 5 h) were investigated comparatively by fretting wear. The results showed that the thickness of the oxide layer and the average content of element O on the surface were gradually increased with increasing temperature. Lower friction coefficients were observed in coatings at 200–400 °C for 1 h. Better performance of crack-healing features was demonstrated at 400 °C, whereas fresh microcracks were formed under the fretting condition due to the fragility of oxides at the same time. The tribological behavior of thermal oxidation-treated Ti3SiC2 coatings was mainly controlled by delamination and abrasive wear. The volume losses induced by wear scars decreased with the increase in oxidation time under the oxidation treatment at 200 °C and increased with increasing oxidation time under the oxidation temperatures of 300 and 400 °C.

“…Fretting wear is a wear phenomenon caused by the relative oscillation of small displacement amplitude between two contact interfaces in tangential motion [62][63][64][65][66]. The PBF technology has been widely used in the medical field, mainly in the manufacture of artificial joints, artificial bones and so on.…”

Powder Bed Fusion (PBF) is an additive manufacturing technology used to produce metal-based materials. PBF materials have a unique microstructure as a result from repeated and sharp heating/cooling cycles. Many researches have been carried out on relations between processing parameters of the PBF technology, obtained microstructures and mechanical properties. However, there are few studies on the tribological properties of PBF materials at various contact conditions. This article describes previous and recent studies related to the friction performance. This is a critical aspect if PBF materials are applied to friction pair components. This paper discusses wear rates and wear mechanisms of PBF materials under dry friction, boundary lubrication and micro-motion conditions. PBF materials have higher hardness due to fine grains. PBF materials have a higher wear resistance than traditional materials due to their solid solution strengthening. In addition, hard particles on the surface of PBF components can effectively reduce wear. The reasonable combination of process parameters can effectively improve the density of parts and thus further improve the wear resistance. This review paper summarized the wear behavior of PBF materials, the wear mechanism of metal materials from dry friction to different lubrication conditions, and the wear behavior under fretting wear. This will help to control the processing parameters and material powder composition of parts, so as to achieve the required material properties of parts and further improve the wear performance.

“…Wear test specimens were extracted from the fabricated parts by wire electro discharge machining with a dimension of 30 mm (length) × 30 mm (width) × 7 mm (thickness). Details about wear test configuration can be found in our previous works [18][19][20][21]. The experimental parameters were set based on the practical operating conditions of the blade bearing [16].…”

Additive manufacturing (AM) nickel-based superalloys have been demonstrated to equate or exceed mechanical properties of cast and wrought counterparts but their tribological potentials have not been fully realized. This study investigates fretting wear behaviors of Inconel 625 against the 42 CrMo4 stainless steel under flat-on-flat contacts. Inconel 625 is prepared by additive manufacturing (AM) using the electron beam selective melting. Results show that it has a high hardness (335 HV), superior tensile strength (952 MPa) and yield strength (793 MPa). Tribological tests indicate that the AM-Inconel 625 can suppress wear of the surface within a depth of only ~2.4 μm at a contact load of 106 N after 2 × 104 cycles. The excellent wear resistance is attributed to the improved strength and the formation of continuous tribo-layers containing a mixture of Fe2O3, Fe3O4, Cr2O3 and Mn2O3.
