Study comparing the tribological behavior of propylene glycol and water dispersed with graphene nanopowder

Nanofluids made up of propylene glycol, and water and graphene nanopowder dispersed throughout them are the primary focus of our study. Nanofluids were created by mixing propylene glycol and water in quantities of 100:0, 75:25, and 50:50. The essential fluids used in this experiment were propylene glycol and water. Graphene was dispersed in these three different base fluids at percentages of 0.25 and 0.5, respectively. This body of work's fundamental objective is to explore nanofluids' tribological behavior. This behavior was observed with a pin-on-disc device, and the impact for load on wear, coefficient of friction, and frictional force was investigated. The tests were conducted with weights ranging from 1 to 3 kg. It was revealed that as the load ascended, there was a reduction in the amount of wear, the coefficient of friction, and the frictional force for the most of the samples tested. Still, there was an increase in the amount of wear and friction coefficient, including the frictional force for some of the samples.

Automated summary

The study focuses on nanofluids consisting of propylene glycol, water, and dispersed graphene nanopowder. Nanofluids were prepared by mixing propylene glycol and water in ratios of 100:0, 75:25, and 50:50. The main objective is to investigate the tribological behavior of nanofluids using a pin-on-disc device. The effects of load on wear, coefficient of friction, and frictional force were examined, revealing a reduction in wear, friction coefficient, and frictional force for most samples with increasing load, but an increase for some samples.
