The influence of oxide layers on the physical properties of the bonding of composites will be investigated using multiscale simulations to understand different production processes. In particular, process conditions that lead to high-quality, metallurgically-bonded compounds are identified. The basic dependencies of the bond strength on oxygen concentration, temperature and oxide layer thickness will be investigated for interfaces. The hardness of the materials as an indicator for the quality of the joint will be determined experimentally by nanoindentation and compared with simulation values. By transferring the results to larger length and time scales, a cross-scale model for the fundamental understanding of the processes of joining technology is to be developed.
