Graphite nanoplates as grease lubricant additive: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0



This paper presents the outcomes of a examine of the impact of the graphite nanoplates (GNP) focus on the tribological and rheological traits of grease lubricants based mostly on used motor oils and calcium soaps. GNP have been obtained by the unique electrochemical methodology. Grease lubricants have been examined for residual water content material, dropping level, penetration, and put on restrict. The dimensions of damage spot was decided utilizing a four-ball friction machine. It was discovered that by GNP content material rising the water content material monotonically rises from 0.6 to 2.3 wt. %. The penetration decreases from 44 to 31 mm with rising 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 dimension of damage spot (0.215 mm) can also 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.
