• Nitrogen ion implantation
• Ti6Al4V
• Corrosion resistance
• Roughness

In this project the effect of nitrogen ion implantation on the corrosion resistance of Ti6Al4V alloy is studied. Nitrogen ions are implanted with four fluences from 8 x 10(17) to 5 x 10(18) ions/cm(2) in the Ti6Al4V substrates. The effect of ion implantation on surface morphology and roughness is investigated with Atomic Force Microscopy. X-ray diffraction is used for phase analysis of the samples and as a result Ti(2)N(105) in the fluence of 1 x 10(18) ions/cm(2) and TiN in fluence of 2 x 10(18) ions/cm(2) are observed. For corrosion resistance analysis in one molar sulfuric acid a potansiostate device is used and the best corrosion resistance is obtained for the fluence 2 x 10(18) ions/cm(2). Moreover corrosion resistance variation is explained by microstructure considerations.
