Surface Nanocrystallization and Surface Alloying of Nonferrous Alloys (2005-2009)
Abstract
Surface mechanical attrition treatment will be used to generate nanometer-sized grains in the surface layer of various nonferrous alloys and therefore activate the surface of these materials. This together with the discovery of more efficient activators will allow the development of a novel low temperature surface alloying technique to significantly improve the wear and corrosion resistance of these alloys without changing the substrate properties. This will considerably increase the service life of components in automotive and aeronautical applications. Microstructural features in the ultrafine-grained surface layer will be examined and a mechanism for fast atomic diffusion in nanomaterials will be developed
