The tribo-contact i.e. the combination of two surfaces and if applicable a confined lubricatn represents one of the most demanding construction elements in engineering. The complexity of friction is based on its inherent multiscale behaviour. Consequently, a computer-aided material design of tribo-contacts has to cover all scales from elasto-hydrodynamics down to the quantum description of the calence electrons. Based on tribologically relevant examples, an introduction into multiscale methods will be given. Areas of applications (e.g. the search for possible additive-surface reactions or low friction surfacestructures) will be localised and discussed.
