Summary
This paper presents the outcomes of a research of the impact of the graphite nanoplates (GNP) focus on the tribological and rheological traits of grease lubricants primarily based on used motor oils and calcium soaps. GNP had been obtained by the unique electrochemical methodology. Grease lubricants had been examined for residual water content material, dropping level, penetration, and put on restrict. The dimensions of wear and tear spot was decided utilizing a four-ball friction machine. It was discovered that by GNP content material growing the water content material monotonically rises from 0.6 to 2.3 wt. %. The penetration decreases from 44 to 31 mm with growing GNP content material. Additionally, the dropping level rises from 79 to 88 °C on the GNP focus of 150 ppm, after which decreases to 81 °C. The minimal measurement of wear and tear spot (0.215 mm) can be noticed at a GNP focus equal to 150 ppm. It’s 25.1% decrease than that of the management pattern that doesn’t GNP comprise.
