Abstract
Nanomechanical response of a silicon specimen coated with a sp3 crystalline carbon coating (1.8nm thickness) was investigated using MD simulation. A sharp conical rigid tip was impacted at the speed of 50m/s up to a depth of ~80% of the coating thickness. Unlike pure silicon specimen, no metallic phase transformation was observed i.e. a thin coating was able to resist Si-I to Si-II metallic phase transformation signifying that the coating could alter the stress distribution and thereby the contact tribology of the substrate. The stress state of the system, radial distribution function and the load-displacement curve were all aligned with above observations.
