“…According to the study, a change in load shows an impact on wear rate. The findings were consistent with previous research [33]. The study suggested that inclusion of anti-wear additive in EC-CMC and PTFE will enhance their tribological properties and will be comparable to commercial shell counterpart.…”

This study examined the effects of polytetrafluoroethylene (PTFE) and Eichhornia crassipes carboxymethyl cellulose (EC-CMC) polymers in base jatropha lubricant and employed commercial shell lubricant as the reference. Wear reduction and coefficient of friction (COF) were measured using 1 mass% polymer concentrations. Characterization analysis showed that the formulation processes required functional groups like carbonyl, alkene, aliphatic CH 2 and CH 3 group that the Fourier Transmission Infrared (FT-IR) studies indicated were necessary for lubrication. According to the frictional analysis, the polymers' tribological performance was influenced by changes in both load and operational speed. At 40 kg and 1200 rpm, PTFE and EC-CMC reduced COF by 53.7% and 49.8%, respectively, compared to base jatropha. However, commercial shell oil produced exceptional performance.

Most studies of liquid lubricants were carried out at temperatures below 200 °C. However, the service temperature of lubricants for aerospace and aeroengine has reached above 300 °C. In order to investigate the friction mechanism and provide data for high temperature lubrication, the friction and wear properties of chlorophenyl silicone oil (CPSO)-lubricated M50 steel and Si3N4 friction pairs were investigated herein. Ball-on-disk experimental results show that the lubrication performance of CPSO varies significantly with temperature. Below 150 °C, coefficient of friction (COF) remains at 0.13–0.15 after the short running-in stage (600 s), while the COF in the running-in stage is 0.2–0.3. At 200 °C and above, the running-in time is much longer (1,200 s), and the initial instantaneous maximum COF can reach 0.5. Under this condition, the COF gradually decreases and finally stabilizes at around 0.16–0.17 afterwards. This phenomenon is mainly due to the different thickness of boundary adsorption film. More importantly, the wear rate of M50 steel increases significantly with the temperature, while the wear rate barely changes at temperatures above 200 °C. The anti-wear mechanism is explained as tribochemical reactions are more likely to occur between CPSO and steel surface with the increased temperature, generating the FeCl2 protective film on the metal surface. Accordingly, FeCl2 tribochemical film improves the lubrication and anti-wear capacity of the system. At high temperatures (200–350 °C), FeCl2 film becomes thicker, and the contact region pressure becomes lower due to the larger wear scar size, so the wear rate growth of M50 steel is much smaller compared with that of low temperatures (22–150 °C). The main findings in this study demonstrate that CPSO lubricant has good anti-wear and lubrication capacity, which is capable of working under temperatures up to 350 °C.

“…Through a four-step catalytic process, bio lubricants can also be made from used cooking oil and cyclic oxygenates. Some experts have noted that viscosity is the most significant characteristic of lubricants since it controls the degree of friction between two surfaces 13,20) . Higher viscosity lubricants have lower wear rates and a higher viscosity ratio, which reduces wear 20) .…”

Bio lubricants derived from biomass can lessen the carbon footprint of production, lubrication, and energy production. When nanoparticles (NPs) additives are used, the performance improvement from the usage of bio-lubricant is more pronounced. This brief review highlights the key characteristics of current bio lubricants and the argument for utilizing sustainable bio lubricants that may be produced from agricultural feed stock with the potential to replace conventional mineral oil products. There is a need to shift to waste-derived oils and conduct research on alternative sources of bio-products to address the challenges of the lubricant/food competition, even though existing studies on bio lubricants have primarily focused on the use of vegetable oils and some non-edible oils. Most NPs additives combined with bio-lubricant, according to the literature, have the potential to reduce wear and friction. Furthermore, it was discovered that the NPs mechanisms during operations were responsible for the friction and wear reduction from nanofluids application. As a result, sliding contact was converted to rolling, and tribo-film was formed, separating the sliding bodies from direct contact. However, there are several complex problems related to bio-lubricant that should be handled before fulfilling the lubricating need. More thorough research was required to analyze crucial characteristics such viscosity, flash point, thermo-oxidative and storage stability of the oils, techno economics, and sustainability, which will be the focus of future work to resolve these problems.
