“…The pin lubricated with PE at 100 N load displays more wear scars, specifically grooves. This is because the lubricant film between the pin and disc has completely broken, indicating that PE was unable to sustain the continuous formation of film between the surface at high loads and during operation [29,30].…”

Biolubricants are being developed more frequently as a result of environmental issues, which also improve performance and lessen friction and wear. This study seeks to examine the effects of commercial compressor oil-SAE30, and its blend with pentaerythritol ester (PE) derived from vegetable oil on tribological properties. Two sequential transesterification processes were used to create the pentaerythritol ester made from vegetable oil utilizing the ultrasonic irradiation method. Using an air compressor lubricant, load, and sliding speed for each experimental run, a pin-on-disc tribometer is utilized to examine the friction and wear characteristics of the material. According to the experimental findings, PE 75 (75 vol.% - PE and 25 vol.% - SAE30) performs better than PE and SAE30 in terms of minimum coefficient of friction (COF) and specific wear rate (SWR) under high loads and high sliding speeds. Furthermore, scanning electron microscope (SEM) and Energy Dispersive Analysis of X-Ray (EDAX) analyses were used to examine the morphology behavior of the pin surfaces. Due to the coating that covers the specimen's surface, PE 75 compressor oil displays smoother surfaces than other lubricated surfaces.

The growth of the machinery and automotive industry drives interest toward the production of biolubricants due to their better lubricating properties and their low carbon footprint compared to petroleum-based lubricants. However, their traditional synthesis is long and energy-intensive. We intensified the production of biolubricants from canola oil methyl esters using ultrasound. NaOH catalyzed the transesterification of two polyalcohols (propylene and trimethylene glycols). We varied the ultrasound power, temperature, type of alcohol, and alcohol/ biodiesel molar ratio. Trimethylene glycol produced 90 ± 1.9% of biolubricant at 80 °C and 62 W with a molar ratio of 0.25. Calcium oxide supported on silica (CaO/SiO 2 ) also catalyzed the reaction under optimal conditions. The yield of the CaO/SiO 2 -catalyzed reaction was two times lower than that obtained with NaOH. We surveyed the loading of CaO over SiO 2 , the catalyst loading in the reactor, and its leaching and reusability. A mass percentage of 50% CaO to SiO 2 yielded 46 ± 3.2% lubricants at 3% by weight of the reactants' total mass. After three reaction cycles, the ultrasound did not alter the particle size (e.g., mean diameters of fresh and used catalysts were 31 and 32 μm, respectively), but it leached the active sites, which reduced the activity of the catalyst for successive uses.
