Nanomodification of forming tool surface by ion implantation

Abstract

In this paper the issue of ion implantation and its significance for ultra precision forming tools has been analyzed. An overview of ion implantation processes, influence of ion types and process parameters on enhancement of exploitation characteristics has been given. Some preliminary results have been given which have been conducted using high energy Kr ions obtained from an ECR (Electron Cyclotron Resonance) ion source. These ions have been used for nano modification of cold working steel. The obtained results clearly show that the energy of Kr ions has a great effect on the friction coefficient and roughness of the nano modified layer. An increase of nano hardness can be obtained as well. The preliminary results clearly show that ion implantation is a promising technology for nano modification of forming tools, however, in order to achieve the application of ion implantation throughout the industry a systematic approach to research is needed for the technology of ion implantation as well as for the connection between the exploitation characteristics and the type of applied ion implantation.
