Surface mechanical attrition treatment will be used to generate nanometer-sized grains in the surface layer of engineering magnesium alloys, and therefore activate the surface of this material. Together with the use of efficient activators, the project will develop a novel low temperature surface alloying technique to significantly improve the wear and corrosion resistance of magnesium alloys without changing the substrate properties. Microstructural features and the wear and corrosion resistance of the ultrafine-grained surface layer will be examined. In addition, it may be possible to combine the surface alloying process with the conventional ageing process together in order to save energy.
