“…Furthermore, the debris produced by laser texturing requires the sample to be polished after texturing, thereby adding complexity to the process. These issues can be avoided by using the photolithographic etching [18,25,26], which affords a facile method for making complex textured surfaces merely by changing the shape of the mask used for defining the etching pattern, and obviates the need for polishing the sample after the textures have been formed. The oval shapes textured surfaces have shown good antifriction and antiwear properties in some cases [27].…”

“…In addition, the formation of hydrodynamic oil pockets is regarded as beneficial for the lubrication of textured surfaces under full fluid lubrication [17]. Recently, it was also shown that, in addition to these roles, tribofilm formation during sliding can play an important role in the tribological behavior of the textured surfaces [18]. Furthermore, the nature of the lubrication regime can have a significant influence on tribofilm formation [19][20][21], which ultimately affects the tribological behavior.…”

Lubrication conditions have significant influences on the formation of tribofilms and then affect tribological behavior. In this work, the influence of tribofilm formation on the tribological behavior of textured surfaces with oval shapes was measured using a pin-on-plate tribometer. The results show that, under full lubrication, the adsorbed oil film controlled the friction and wear behavior of steel/steel tribopairs but under starved lubrication, the formation of a tribofilm significantly influenced the tribological behavior. The appropriate textured surfaces with oval-shaped dimples contributes to obtaining excellent antifriction and antiwear behavior. However, excessively high ratios of the major to the minor axis of the oval can result in high contact stresses which can destroy the tribofilm.

“…This peak is ratified by the lowest Fe 2p intensity, shown in Fig. 11(b), suggesting that the thickest adsorbed film covered the substrate steel surface [30]. These trends may be one reason for the best antifriction and antiwear roles at this concentration for TiL 4 /BP nanocomposites as additives.…”

In the present work, two types of novel nano additives, titanium sulfonate ligand/black phosphorus (TiL 4 /BP) and titanium dioxide/black phosphorus (TiO 2 /BP) nanocomposites, were prepared. The tribological behavior of the steel/steel friction pairs lubricated by polyalphaolefins type 6 (PAO6) containing the nanocomposites under boundary lubrication was studied. The worn surfaces were analyzed using modern surface techniques. The experimental results show that the rubbed surfaces became smooth and showed little wear with the addition of the nanocomposites. TiO 2 /BP nanocomposites can significantly improve the lubricity of BP nanosheets under high contact stress. The synergistic roles of the load-bearing abilities and rolling effect of TiO 2 nanoparticles, the slip induced by the BP with its layered structure, and the establishment of a tribofilm on the sliding interface are the basis of the tribological mechanisms.

“…46 The presence and buildup of tribofilm during sliding can have significant effect on the tribological performance of textured surfaces. 47 Until now the understanding of the effect of roughness on the growth of tribofilms is missing and no framework or instructions are available that link the performance of surfaces in growing tribofilms to the roughness parameters. Brizmer et al 24 performed simulations to study the effect of root-mean-square (RMS) roughness on the mean tribofilm growth but only three data points were used to develop a curve.…”

In recent years, several theoretical models to predict the triboreactive film thickness of zinc dialkyldithiophosphates (ZDDP) have been developed. Although these models are not complete and are approximate in nature, they provide a framework which can be used to evaluate the factors impacting the tribofilm growth. In this paper, rough surfaces with different roughness parameters were numerically generated and used to calculate the tribofilm growth. The simulation results show that lower negative skewness, higher kurtosis, and larger autocorrelation length values give thicker ZDDP tribofilms with skewness and autocorrelation values having a greater effect on the tribofilm growth. Based on the simulation results, it is found that these parameters influence the tribofilm growth by changing the contact ratio which eventually changes the dynamic growth of tribofilm and wear of substrate. The results presented in this paper have bigger implications for industry in designing surface textures that promote the anti-wear action.
