“…EAM potentials comprise a pairwise repulsive term modeling the core-core interaction and a cohesive contribution representing the energy that an ion core experiences when it is "embedded" in the electron density originating from neighboring atoms. Examples of their application in tribology are studies of the frictional behavior of an indenter tip against different metallic surfaces [278][279][280][281], or the interfacial friction characteristics of different metal pairs [282]. For carbon-based (e.g., diamond, graphite/graphene, diamond-like coatings, nanotubes) and other covalent systems, a series of FFs has been developed, all based on the bond order concept originally formulated by Pauling [283].…”

“…They concluded that the most significant factor in determining the wear process is inter-asperity bonding. Lin et al [14] identified the dynamic process of dry interfacial friction between Cu/Fe and Cu/Ag metal tribo-pairs, and demonstrated that a rapid increase in temperature occurred when two blocks were sheared, and also observed that extensive plastic deformation and material transfer between blocks occurred. Spijker et al [15] carried out an atomic simulation of dry sliding contact with 3D rough surfaces and found that by varying the surface roughness, sliding speed, and applied normal load, the friction force increased with a larger wall roughness.…”

“…The mixing was found to be diffusive or "superdiffusive", depending on the coherence between interfaces. Heat dissipation due to sliding was investigated by means of non-equilibrium Molecular Dynamics simulations [24,25]. Atomic-scale mechanical mixing and generation of mixing layer were observed in the regions near the contact interface.…”
