Investigation of Microstructure and Properties of Surface Nanocrystallization Layer by Rolling Technology

Abstract:

This article will introduce a new type of surface nanotechnology, that is the Surface Nanocrystallization technology by pre-forcing rolling. A nanocrystalline surface layer was fabricated on deposited layer by using pre-forceing rolling technology (PFRT) .The microstructure of treated specimens was characterized by using scanning electron microscopy and transmission electron microscopy. Experimental evidence showed, The technology can form a smooth surface on the parts, so it can be used as the last process of the machining. The equipment has a simple structure, similar to ordinary lathe tool, so can be used in the ordinary lathe or the machining center. Experimental analysis indicated the coars crystal in the surface layer could be refined into nanocrystalline by using the pre-forceing rolling technology, attaining optimizing surface structure of metal parts.
