This review article presents the results of molecular dynamics simulations of sliding processes and sliding experiments using a friction force microscope to clarify the sliding friction phenomena between a diamond slider and a copper specimen in the air and to reduce the gap between the experiments and molecular dynamics simulations. In the simulation model, both the adhesion effects obtained through the nanocontact experiments in the air and the effects of the oxide film generated in the uppermost specimen surface were considered. From the comparisons between the simulation and the experimental results, it was confirmed that they have good similarities in the friction coefficients. From the simulation, the breaking mechanism of the oxide film was also clarified by observing the slip deformation generated in the copper specimen.
