“…The wear scar surface morphologies of the as-received and machined samples are demonstrated in figure 10 and it is found that the as-received sample depicts the stack of wear debris along with larger grooves (figure 10(a)), due to the existence of tensile residual stress over the surface. Further with increase in table feed causes a surface becomes harder up to 25 mm min −1 which offer the machined surface become superior against material deterioration and it confirmed in figure 10(c), due to the presence of minimal wear debris [24]. Further increase in table feed up to 45 mm min −1 , leads to arise the wear rate slightly, due to the presence of moderate strain toughening effect and disorder.…”

“…The as-received sample exhibits a coefficient of friction and wear rate of 0.82 and 22.5±0.04×10 −5 mm 3 Nm −1 and the subsequent machining process under BEH condition has discovered the minimal coefficient of friction and wear rate of 0.48 and 4.55±0.03×10 −5 mm 3 /Nm. This decrement in wear rate over the machined surface leads to increase its wear resistance, through the decrement in surface deterioration [24]. The worned surfaces under different machining conditions are discussed in the followings.…”

The slot milling process has a profound effect on surface characteristics such as residual stress and wear resistance, owing to the introduction of severe plastic deformation over the machined surface. Because the establishment of enormous pressure during machining operation leads to enhance its surface characteristics such as hardness and wear resistance through a significant increment in residual stress This study aims to analyze the impact of machining conditions such as spindle speed, table feed and depth of cut on the quantifiable contributions of the enhancement in surface characteristics such as microcrystalline characteristics and residual stress on the machined surface using XRD spectra analysis. Furthermore, it is found that the table feed has a great impact on the surface characteristics followed by the spindle speed and depth of cut. Additionally, it confirmed that the decrement is table feed leads to declines the augmentation of compressive residual stress drastically, while the depth of cut and spindle speed are kept constant.

“…The lower ball wear diameter and disc wear volume indicate the better anti-wear properties, and vice versa. [51] To value the possibility of the bio-oil as the commercial lubricant base oil, polyethylene glycol 200 (PEG 200) was tested as the control sample. PEG has been successfully used in various applications, such as lubricants and cosmetics.…”

High-value utilization of biomass has been driven by increasingly growing industrial demands. Herein, we offer a strategy composed of depolymerization and esterification reaction of lignin to transfer to bio-oil with high liquid yield (79.75~85.25%), which is demonstrated as a high performance lubricant. Overall, the bio-oil has the excellent lubrication properties, where a significant wear reduction of 97.6% was observed as compared with polyethylene glycol 200. Meanwhile, the more ether and less acid in bio-oil could improve the anti-wear properties. This work provides a new application of utilizing lignin in advanced lubrication systems.

“…In each profile, two reference planes are set, and an area of interest is selected and measured, as shown in Figure 7b. The reason for selecting 2D over 3D volumetric wear measurements is based on a recent report [27] showing that both approaches provide a similar ranking, but 2D measurements have a lower spread of measurement values. Based on this confocal analysis, a relative ranking of candidate coatings and the hard Cr reference in terms of maximum and mean wear depth can be achieved (Figure 8).…”

High Performance Accelerated Tests to Evaluate Hard Cr Replacements for Hydraulic Cylinders

et al. 2021

To prolong the lifetime of hydraulic cylinders, a wear-resistant low-friction surface is required. Until now, hard Cr coatings were the best materials for this. However, in recent years, there has been an increasing pressure on the manufacturing of hard Cr plating and plated products, because of environmental and health hazards. The replacement of these coatings by alternatives has not been highly successful yet, because it requires extensive component testing, which is costly and time-consuming and thus not appropriate for material development. For this reason, there is a high need to develop tribological methods that simulate hydraulic cylinders’ component-testing closely. In addition, these new methods should also provide additional information (e.g., friction evolution) that can assist in the further development and optimization of alternative coatings. Having the above in mind and building on an existing method from the American Society for Testing and Materials (ASTM G133), a new test method that allows users to test directly on hydraulic cylinders was developed. This method can provide a relative ranking of both the wear resistance and frictional performance of alternative coatings in direct comparison to state-of-the-art hard Cr. Importantly, the method is repeatable and has a much shorter test duration than full-scale component tests, thereby accelerating material development significantly.
