“…Controlling the chemical and mechanical properties of tribo-layers can dramatically improve the tribological performance, as recently discovered with the severemild wear transition of the metal materials [16,19]. Uncertain local temperatures, mechanically-driven chemical reactions, and the contact with another body may be factors governing this phenomenon, which was observed in several recent studies involving Cu alloys with stable gradient nanostructures [20], Pt-Au with stable nanocrystalline [21], Ti alloys [16,22], and steels with martensite and pearlite structures [18]. Zhang et al [16] investigated the sliding velocityinduced transition from severe wear to mild wear as a result of the formation of tribo-oxide layers during the Ti-6.5Al-3.5Mo-1.5Zr-0.3Si sliding against GCr15.…”

“…The deformation and fracture of the initially transferred fragments during continuous sliding contact led to the formation of a "mechanically mixed material" on the surfaces of the matrix subjected to wear [18,19,22]. The mixed material layer formed under unlubricated conditions displays considerably higher hardness than the soft disk material due to the localized and thermal effects induced during the friction process [30].…”

“…However, the potentially complex chemical reactions occurring under the tribological contact are highly crucial to the tribological behaviors as the tribo-layers affect the contact mechanics profoundly [13,16]. Tribo-layers, particularly the topmost layer, directly in contact with the environment and their counterpart, primarily determine the friction and generate wear [13,17,18]. Controlling the chemical and mechanical properties of tribo-layers can dramatically improve the tribological performance, as recently discovered with the severemild wear transition of the metal materials [16,19].…”

The tribological behaviors of Ti-Ni51.5 at% alloy strengthened by finely dispersed Ni4Ti3 particles in reciprocating sliding against GCr15, Al2O3, and ZrO2 at room temperature were studied. Interestingly, the coefficient of friction (COF) suffered a sheer drop (from 0.9 to 0.2) when the aged alloy slid against GCr15 at a frequency of 20 Hz under a 20 N load without lubrication. However, severe-mild wear transition disappeared when a solutionized alloy was used. Moreover, the COF stabilized at a relatively high level when Al2O3 and ZrO2 were used as counterparts, although their wear mechanisms showed signs of oxidation. Scanning electron microscopy (SEM) and X-ray element mappings of the wear scars of the counterparts clearly indicate that the formation of well-distributed tribo-layer and material transfer between the ball and disk are pivotal to the severe-to-mild wear transition in the aged Ti-Ni51.5 at% alloy/GCr15 friction pair. The higher microhardness and superelasticity of the aged alloy significantly accelerate the material transfer from GCr15 to the disk, forming a glazed protective tribo-layer containing Fe-rich oxides.

“…Nano-ferroferric oxide (nano-Fe 3 O 4 ) and nano-ferric oxide (nano-Fe 2 O 3 ) solid lubricants have good lubricating properties. They can deposit at the rubbing interface to form layers of tribo-film, thus avoiding direct contact of tribological pairs [4][5][6]. There are four kinds of tribological behaviour of nanoparticles in nano-lubricating oil: 1) Rolling of nanospheres; 2) tribofilm formation as results of tribochemical reactions; 3) mending effect because of the minimal size; 4) polishing effect [7].…”

Graphite‐MoS2‐Fe2O3 (Fe3O4) nano‐composite lubricating coatings were prepared on the surfaces of non‐copper coated solid wires by a mechanical coating technique. The tribological behaviours of graphite‐MoS2‐Fe2O3 (Fe3O4) coatings at the rubbing interfaces of welding wires against the contact tube were investigated. The results demonstrate that the lubricating properties of graphite‐Fe3O4 coatings outperform the lubricating properties of graphite‐Fe2O3 coatings. The anti‐wear performance of the contact tube is strengthened with increasing nano‐MoS2 contents. Layers of protective tribofilms are formed at the rubbing interfaces of welding wires against a contact tube by tribochemical reaction among lubricants. The tribofilms are composed of FeO, MoO3 and FeMoO4 with excellent lubricating properties. They can avoid direct contact of welding wires against the contact tube, thus decreasing contact tube wear. With the transition of the contact tube wear from mild to severe, the dominant wear mechanisms of contact tube change from fatigue peeling and oxidative wear to abrasive wear and arc ablation.

Iron(III) oxide (Fe 2 O 3 ) has attracted great attention, owing to its abundant natural resources, environmental friendliness, and low cost. Nevertheless, this material possesses an inferior rate capability and a cycle stability that is similar to most transition metal oxides. Graphene, with a one-atom-thick 2D structure, possesses superior mechanical properties, electrical conductivity, and stability, and excellent electrical and electrochemical behaviors. The hierarchical structure of graphene/Fe 2 O 3 composites provides a porous conductive network, close contact between the graphene and Fe 2 O 3 , a stress buffer space for charge transport, and superior structural stability. This composite consists of high conductivity graphene with interconnected Fe 2 O 3 , thus exposing abundant active sites for redox reactions and providing sufficient contacts with the electrolyte. Consequently, materials composed of Fe 2 O 3 and graphene have been widely explored, owing to their outstanding synergistic effects. Graphene can effectively limit the volume expansion and agglomeration of Fe 2 O 3 , whereas Fe 2 O 3 can prevent the restacking of graphene at the same time. This article mainly discusses the preparation of Fe 2 O 3 /graphene materials and their applications, including supercapacitors, rechargeable batteries, catalysis, and so forth. In addition, the perspectives and challenges of Fe 2 O 3 /graphene materials for different applications are also discussed.
