Molecular dynamics simulation of nano-scale interfacial friction characteristic for different tribopair systems

► We examine microstructural and temperature evolutions of Cu/Fe and Cu/Ag tribopairs. ► Plastic deformation, amorphization and atom mixing are observed for both tribopairs. ► For Cu/Fe, amorphous Cu recrystallizes into bcc structure on Fe surface. ► Two peak values appear in temperature profile and shift into Cu Part during sliding. ► For Cu/Ag, flatter temperature profile appears with no shift of peak value position.
