Abstract

This paper presents the influence of adding nano graphene particles in soybean oil in different massic concentration (0.25%, 0.50% and 1%) on the tribological parameters: friction coefficient, wear scar diameter. Tests are done on a four-ball machine from the lubricant laboratory LubriTest, at “Dunarea de Jos” University of Galati. The test parameters were load: 100 N, 200 N and 300 N and the speed 1800 rpm. The additive was supplied by PlasmaChem and the dry graphene - nanoplatelets have a thickness: 1-4 nm; particles size: up to 2 µm, purity: 91 at.%. The soybean oil was supplied by Prutul Galati. The test balls are lime polished, made of chrome alloyed steel balls, having 12.7±0.0005 mm in diameter, with 64-66 HRC hardness, as delivered by SKF. The sample oil volume required for each test was 8 ml ±1 ml. The test method for investigating the lubricating capacity was EN ISO 20623:2003 Petroleum and related products - Determination of the extreme-pressure and anti-wear properties of fluids - four ball method.
