Nanotribology (Abrasive wear, Nanofabrication)

This example of Full-Atomistic Molecular Dynamics (FAMD) analysis focuses on nanoscale wear and processing phenomena (nanotribology). It reproduces the abrasive wear process in which sapphire (single-crystal alumina) is pressed and scraped against an iron surface. An EAM potential was used for iron, and a potential based on first-principles calculations was used between iron and sapphire. The analysis visualized the formation of scratch marks on the iron surface, with potential applications in fields such as nanomachining and chemical mechanical polishing (CMP).
