Abstract

We report a study on monocrystalline nickel thin films using the atomic force microscope (AFM) based scratching process to under- stand the associated wear mechanism. As for the nano level fabrication, better understanding of abrasive wear mechanism is a pre- requisite. A three-dimensional molecular dynamics (MD) study has been performed and we have used a new parameter wear volume to distinguish between different wear zones. A reduced number of zones have been proposed to understand the wear mechanism during nanoscratching process. Also, centrosymmetry parameter has been used to validate the findings.
