“…The main obstacle originates from the nature of the tribo-induced reactions that can follow different complex pathways. The reaction pathway changes depending on whether the base oil containing the antiwear additive may also contain adventitious impurities [14], other additives [15,16], detergents [17] and dispersants [18]. The operating conditions [19] and compatibility between the additive and contacting surfaces [20] are also important factors.…”

To enhance the anti-wear property of aluminum–silicon (Al–Si) alloy, three processing technologies—chemical etching, mechanical honing and laser finishing—were compared in terms of their effects on anti-wear performance. The treated Al–Si alloy cylinder liner samples were worn against a piston ring by a reciprocating sliding tribotester; the anti-wear performance was represented by the friction coefficient and wear loss; and the wear mechanism was determined by establishing stress contact models. The results showed that the best time for both the chemical etching and mechanical honing treatments was 2 min, and the optimal laser power was 1000 W for the laser finishing treatment. The three processing technologies could all remove the aluminum layer and make the silicon protrude on the surface to avoid the plastic flow of aluminum during the friction process. The laser finishing could not only protrude the silicon particle but also make its edge rounded and smooth, which decreased the stress concentration. Therefore, the Al–Si alloy cylinder liner treated with laser finishing had the best anti-wear performance.

“…The lubricant performance can be improved by the addition of different additives such as antiwear, antifriction, extreme pressure (EP), anticorrosion, and viscosity modifier . The commercially available additive such as zinc dialkyldithiophosphate (ZDDP), a well‐known multifunctional additive and completely soluble in oil, is invariably used in the lubricants . However, there is a limitation in using ZDDP in the lubricants due to the presence of sulphur and phosphorus content, which are not environment friendly .…”

However, there is a limitation in using ZDDP in the lubricants due to the presence of sulphur and phosphorus content, which are not environment friendly . Therefore, low SAPS or zero SAPS (sulphated ash, phosphorus, and sulphur) additives are emphasized as lubricant additives to protect the environment from the hazardous exhausts .…”

In the present work, calcium-copper-titanate (≈85 nm) and cerium oxide (≈90 nm) nanoparticles were blended in paraffin oil (PO) as an additive by varying the concentration from 0.1 to 1.0% w/v, and tribo-performance was evaluated with four-ball tester. The concentration 0.25% w/v of the nanoparticles in PO was found to be optimum in antiwear and antifriction property tests for both types of nanolubricants. At this particular concentration, the maximum reductions in the wear scar diameter were 38.4 and 26.1% for calciumcopper-titanate and cerium oxide-based nanolubricants, respectively. Also, the mean coefficient of friction was reduced by 17.3 and 29.6% at this optimum concentration for both types of lubricants. For extreme-pressure test, the loadcarrying capacity of the nanolubricants was improved from 126 to 160 kgf as compared with base PO. The worn surfaces were examined with scanning electron microscope, energy-dispersive spectroscopy, and atomic force microscope to study the physical phenomena that occurred during the sliding.
