Wear Mechanisms of Steel Under Boundary Lubrication in Presence of Carbon Black and Graphite Nano-onions Particles 2008-01-2461
Both carbon blacks and carbon nano-onions nanoparticles have a spheroidal shape and a nested structure. They can be used to simulate the presence of soots in used engine oils. When added to fully formulated fresh engines oils, these two kinds of particles behave very differently. Carbon black particles are highly abrasive causing a lot of wear of steel surfaces and friction increases. At the opposite, the addition of carbon onions in lubricant leads to a reduction of both friction and wear compared to pure base oil. This shows that there is an opportunity to control wear in engines by changing the structure of soots during the combustion process.
