Indentation and Scratching on the Nanoscale
摘要
Indentation and scratching of Fe, as a model of ferritic steels, are studied by atomistic simulation and experiment. The modeling allows to include the effect of lubrication. Selected experiments reveal the relevance of the nanoscopic simulation results to real surface scratching. We study the evolution of plasticity under indentation and scratching, the dependence of scratching on surface orientation and scratch direction, the influence of tip geometry on scratching, the effect of lubrication during scratching, and friction and wear on micro- and nanoscales.
