报告摘要：Friction and wear significantly impact societies, economies, and the environment. Friction losses alone amount toa fifth of global energy production. This figure is even more severe if wear and its related costs for parts replacement, materials production, and resource depletion are considered.Interactions between materials in sliding contacts are complex and involve structural and chemical effects. Contacts between material surfaces initiate at nanoscopic asperities thatcan be experimentally realized under controlled conditions by applying atomic force microscopy as a nano tribometer.This lecture overviews recent experimental results on the friction and wear of various materialsatthenanometerscale,andemphasizestheroleof2Dmaterialsandsurfaceoxides to control friction and reduce wear.
