“…A large amount of polymer filled in the groove is thermally expanded under the combined effect of high temperature and high sliding speed, which then forms a transfer film on the sliding surface. However, under higher temperature, the transfer film was rapidly consumed, resulting in a high wear rate under higher sliding speeds [ 14 ]. The hardness of UP is higher than EP and PF, and the polymer in U0 does not easily form a transfer film on the sliding surfaces, leading to a high friction coefficient.…”

“…In the initial stage, the friction coefficient is high as the steel asperities are in direct contact with each other, which induces a large amount frictional heat generated on the contact surface. The thermal expansion coefficient of the polymer is much higher than that of the steel sheet [ 14 ], and the polymer expands to the frictional surface by thermal stress (as shown in Figure 11 a). In the following, polymer adheres on the surface and forms a discontinuous transfer film under the crush of a steel ball.…”

“…Additionally, we fabricated steel-polymer laminated composites and studied the tribological performances. It was found that the polymer with a 40% filling rate had better tribological performance [ 13 ], and the lubrication mechanism was simulated by using a thermo-mechanical model [ 14 ]. Meanwhile the tribological performances of steel-polymer laminated composites under high temperature [ 15 ] and a magnetic environment [ 16 ] were both discussed.…”

In this paper, three kinds of polymer, of epoxy resin (EP), phenolic resin (PF), and unsaturated polyester (UP), were used as fillers to prepare the laminated composite surface, and the tribological properties of a composite surface were studied under dry sliding condition. The results showed that: (i) the composites surface without MoS2 exhibited high friction coefficient and high wear rate at 25 °C, while the friction coefficients were reduced when the temperature increases to 100 °C; (ii) with the addition of MoS2, the friction coefficient of the epoxy resin composite containing MoS2 (E1) was below 0.22 under a temperature of 25–150 °C, and the friction coefficient was increased to 0.32 as temperature increased to 150 °C, while the average friction coefficient of the unsaturated polyester composite containing MoS2 (U1) was very low and below 0.20 under a temperature of 25–150 °C. Analysis of the wear scars indicated that, for the MoS2-containing composite, the transfer films of the E1 and U1 were smooth and continuous under low temperature, while the transfer film of U1 was comparatively complete than that of E1 under 150 °C. The composites with solid lubrication had excellent high-temperature self-lubricating properties, which was attributed to the synergistic effect of the laminated structure, and the thermal expansion of the polymer, and finally a transfer film was formed on the sliding path.

“…Zhang et al [39] has studied the tribological behavior on a sheet laminated part from silicon-steel sheets, between which were introduced MoS2 and graphite. The test was performed on a ball-on-disc tribometer [39], on which the counterpart was a steel ball. This addition of MoS2 and graphite ensured selflubricating properties for the sheet-laminated part.…”

Technology based on additive manufacturing is rapidly emerging and is being used in a wide range of industries. Meeting the precision and accuracy (P&A) requirements of 3D printed parts (shape and size tolerances, surface quality, etc.) is increasingly becoming an issue. This paper presents a critical analysis of the tribological problems encountered in 3D printing for parts manufactured through different types of technologies, such as powder bed fusion, binder jetting, direct energy deposition, material jetting, fused filament fabrication, vat photopolymerization, sheet lamination, and ultrasonic consolidation. For all these additive manufacturing technologies, this paper will present a brief description, classification, examples of materials used, and tribological problems of the obtained machine parts.

“…Such poor tribological performance of polymers can be improved by adequately incorporating nano or micro particles and fibers into the polymer matrix. Our previous work [3] showed the possible improvement of polymer tribological behaviors by appropriately embedding graphite and MoS 2 particles. Jitendra [4] improved the friction and wear behavior of polymer composite by adding talc and graphite powders and showed that the friction coefficient and wear rate of SU-8 composites decreased as comprehensive usage of talc and graphite.…”

Abstract:To improve the tribology properties of the polymer coating under elevated temperature, the epoxy coating was reinforced with nano graphene. The micro-hardness, heat conductivity, and thermo-gravimetric properties of the coating were enhanced as filled graphene. The friction and wear properties of the polymer coating were studied using a pin-on-disc tribo-meter under room and elevated temperatures. The results showed that under room temperature, the friction coefficient and the wear rate of the coating adding 4.0 wt % graphene was 80% and 76% lower than that of the neat epoxy coating, respectively. As the test temperature increased, the friction coefficient of the graphene/polymer coatings decreased at first and then slightly increased. The friction coefficient was at its lowest value under 150 • C and then increased as the temperature rose to 200 • C. By adding 4.0 wt % graphene, the friction coefficient and wear rate of the polymer coating were further reduced, especially at elevated temperatures.
