Mechanical Analysis and Identification Markings of Nanoparticle Distribution in Narrow Friction Zones

Abstract

Through scanning electron microscope (SEM) observation on kinetic friction and static friction deformation, our data show that granular nanoparticles (commonly 60-80nm with diameter, d) are widespreadly distributions in narrow friction zones. Furthermore, the identification markings, such as nature, experiment and fabric orientation etc., usefully deal with the mechanical analysis,and the granular nanoparticle distributions in narrow friction zones could be subdivided into three kinds, i.e. simple shear, pure shear and rotational shear pattern. Additionally, note that under stress action physico-chemical phase changes might be respectively caused by internal cohesion and dynamic differentiation in the narrow friction zones. These analyses deduce that some few complex idea fields, including structural stress, physics and chemistry field, with spatial and temporal evolution exist in the narrow friction zones, moreover, they viably regulate the nanoparticle distribution.
