Summary

The increase in environmental pollution and the decrease in resources both demand to shorten the energy consumption for the acceleration and deceleration of moving masses. To reach this goal the automotive industry focuses on the reduction of vehicle weight. The use of light-weight metallic materials in construction - of which magnesium has the lowest density - is supposed to grow significantly in near future. However, if compared to aluminium, the use of magnesium alloys is obstructed by their inferior mechanical and thermochemical properties as well as by problematic processing. A mechanical surface treatment after machining can be used to improve surface and subsurface characteristics in spite of the poor formability and known influence of strain on corrosion fatigue of Mg-Al-alloys. Compared to shot peening with either glass, steel or water, roller burnishing has the advantage that there is no danger of embedding impurities in the workpiece surface that might support corrosion.
