New adhesive wear law of micromechanical surface contact (original) (raw)

This study presents a new adhesive wear law that builds upon classical concepts of surface adhesion, specifically targeting micromechanical surface contact in rough materials. The research highlights the limitations of existing models, particularly Archard's wear law, by introducing an alternative formulation that accounts for elastic deformation and interatomic adhesive forces in multiasperity contacts. The findings provide a theoretical framework for calculating wear volume more accurately, demonstrating that adhesive wear is significantly influenced by the real area of contact, surface roughness, and load applied.
