Abstract

Abstract

Implantation-enhanced hardening of a Ti-2Al-2.5Zr alloy by 75keV nitrogen ion implantation with the dose of 3×10¹⁷ N⁺ cm^-2 and 8×10¹⁷ N⁺ cm^-2 is investigated. The surface characterization of samples was studied by XRD and Vickers hardness tests. The nitrogen implantation increases the surface hardness up 340% and 260 for the dose of 8×10¹⁷ and 3×10¹⁷ N⁺ cm^-2, respectively. The results of XRD analysis show that TiN is formed in the surface region. Nitrogen-ion-implantation-enhanced hardening is mainly due to the formation of TiN.
