Experimental Investigation of The Mechanical and Surface Properties of Submicrometer Spherical Carbon Particles Used to Enhance Oil Tribological Perfo

Mechanical failure and energy loss in most mechanical systems (such as engines) are mainly due to friction and wear. Energy loss can be reduced using sub micrometer solid particles as dry powder or as additives to conventional oil lubricants. Spherical carbon particles with diameter range from 100 nm to 500 nm were demonstrated as effective solid additives for liquid lubricant to minimize friction and wear losses. The main objectives of this study are to experimentally investigate the lubricating mechanism as well as the surface and

mechanical properties of the sub micrometer carbon particles using an atomic force microscopy and scanning

electron microscopy. The currently available atomic force microscopy will be instrumented to allow for adhesion, friction, and elasticity measurements for the spherical carbon particles. Furthermore, scanning electron microscopy will be utilized to obtain high resolution images and perform chemical analysis for carbon particles.
