“…16 Zheng-zhi Wang et al 17 have studied the effects of wear load, pass (a pattern of scan cycles), and nanoparticle content on the wear behavior of silica nanoparticlereinforced composites. The tribological behavior of carbon-zinc oxide composite coatings using an atmospheric pressure plasma jet method is evaluated by Penkov et al 18 The effects of matrix content on the strength and wear of woven roving glass/polyester and glass/phenolic composites have been examined by Vishwanath et al 19 Srinath and Gnanamoorthy 20 have studied the sliding wear performance of polyamide 6 clay nanocomposites in water. They concluded that addition of clay affects the crystallinity of the nanocomposites, which in turn affects the plasticization.…”

Fiber-reinforced polymer composites are nowadays used in numerous applications due to their good tribological, mechanical, and thermal properties. In the present investigation, the tribological behavior of polyether ether ketone (PEEK) and PEEK reinforced with glass fiber (GF) has been investigated using the pin-on-disk wear tester under dry sliding condition at different applied loads, speeds, and sliding distance. Modeling and optimization of tribological parameters is carried out using response surface methodology (RSM)-based D-optimal design. Tribological parameters such as load, sliding speed, and sliding distance are chosen as numerical factor, and the weight percentage of GF content is considered as the categorical factor. An experimental plan of four-factor (three numerical þ one categorical) D-optimal design based on the RSM is employed to carry out the experimental study. The wear performances of PEEK matrix composites are evaluated using the performance indicators such as specific wear rate and coefficient of friction. The morphologies of the worn surfaces are observed using scanning electron microscopy and atomic force microscopy.

“…The friction and wear mechanism of such doped ZnO thin films was attributed to nanocrystalline features such as the grain population and substoichiometry of the layer. The friction behavior of carbon-ZnO composite coatings was also studied by Penkov et al [15]. They pointed out that the C-ZnO coatings demonstrated better tribological behavior compared with pure ZnO.…”

“…Improvement in tribological properties was attributed to better mechanical properties. Compositing ZnO and organic polymers has also been shown to improve tribological performance and thermal stability, as well as nanochemical properties [14][15][16][17][18][19]. Furthermore, in terms of lubricant additives, compositing ZnO submicrospheres with Al 2 O 3 nanoparticles had been shown to notably improve both the friction reduction and antiwear properties [20].…”

N-doped ZnO thin films were deposited on 304L stainless steel through the pyrolysis of zinc acetate and ammonium acetate in different ratios at a temperature of 420 °C using metal organic chemical vapor deposition. Compositional and structural analyzes of the films were performed by using Rutherford backscattering spectroscopy and X-ray diffraction. The frictional behavior of the thin films and 304L stainless steel substrate was evaluated using a ball-on-flat configuration with reciprocating sliding under marginally lubricated and fully flooded conditions. Al alloy (2017) was used as ball counterface, while basestock synthetic polyalfaolefin oil (PAO10) without additives was used as lubricant. The flat and ball counterface surfaces were examined to assess the wear dimension and failure mechanism. Under marginally lubricated condition, N-doped ZnO thin films provided significant reduction in friction, whereas the films have minimal or no effect in friction under fully flooded condition. N-doped ZnO thin films showed a significant effect in protecting the ball counterface as wear volume was reduced compared with that of the substrate under the marginally lubricated condition. Under the fully flooded condition, with the exception of one of the films, the wear volume of the N-doped ZnO thin films ball reduced compared with that of the substrate. In all the ball counterfaces for N-doped ZnO thin films under both conditions, wear occurred through abrasive mechanism of various degrees or mild polishing. Thus, superfluous lubrication of N-doped ZnO thin films is not necessary to reduce friction and wear.

“…Unlike macro-scale systems in which bearings and lubrication provide excellent means to reduce friction, they cannot be employed for micro-scale systems because of limited size and surface tension effect of liquid lubricants [22][23][24][25]. Therefore, other techniques have been proposed for micro-scale systems such as thin-film solid lubrication and vapor phase lubrication (VPL) [26][27][28][29][30][31][32]. However, it is difficult to deposit solid lubricant coatings on the side walls of micro-scale structures with very small gaps.…”
