SURFACE CHARACTERIZATION OF TITANIUM ALLOYS FOR NITROGEN ION IMPLANTATION

Petr Vertat, Jan Drahokoupil, Petr Vlcak

Abstract


Ion implantation is one of the modern methods of the surface modification of various materials. Industrially used Ti–6Al–4V titanium alloy and commercially pure Ti grade 2 were characterized using the X–ray diffraction methods. Texture of the material and dependence of the microstructural properties on the method of the surface modification were examined in order to determine suitable conditions for application of the process in the industry. The structure of Ti–6Al–4V alloy before and after the nitrogen ion implantation process is discussed and observed surface hardening is explained.
