Abstract
This study investigates the tribological performance of graphene oxide (GO) nanosheets as additives in deionized (DI) water. Four different water-based lubricants were prepared, including supernatant and redispersed solutions, both with and without surfactant. GO supernatant had a significantly lower particle size compared to GO redispersed at all pH levels. The results show that in the absence of a surfactant, the addition of 0.06 wt% GO nanosheets led to maximum of 54 % reduction in the average coefficient of friction (COF). The introduction of surfactant further enhanced this effect, reducing the COF by up to 84 %, compared to DI water. The wear track width was also decreased by up to 353.8 %.
期刊介绍：
Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International.
Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
