Fracture of Surface on an Atomic Scale

Excerpt

Wear on a very small scale is the detachment of atoms and molecules from the bulk surface due to localized heavy deformation. Obviously, wear is not a favorable phenomenon in micro and nanotribology. Recent progress in SPM has shown atomic scale deformation and fracture of mating surfaces. The SPM techniques have been used to study surface roughness, adhesion, friction, wear, scratching, indentation, transfer of materials, etc. [1]. SPM studies on wear at nanoscale, however, have largely been devoted to hard disk drives (HDD). Wear of Si and Si oxides [2], [3], monotonic increase in wear volume of Au with the external load [4], adhesion of silica spheres [5], visible wear of mica [6], onset of wear of self-assembled monolayers (SAM) [7] and abrasive wear of KBr(001) [8], [9] have been published in the literature.
