摘要：

A Mo-N surface modified layer on Ti6Al4V alloy was obtained by the double glow plasma surface alloying technique. The structure and composition of the Mo-N modified Ti6Al4V alloy were investigated by X-ray diffraction (XRD) and glow discharge optical emission spectroscopy (GDOES). The surface-modified layer contains a Mo-N coating in the subsurface and a diffusion layer between the subsurface and substrate. The X-ray diffraction analysis reveals that the outmost surface of the Mo-N modified Ti6Al4V alloy is composed of Mo2N. The friction and wear behaviors of the Mo-N modified Ti6Al4V alloy sliding against corundum balls in Hanks' solution were investigated and compared with that of Ti6Al4V alloy. The results show that the Mo-N modified Ti6Al4V alloy has better friction reduction and higher wear resistance properties than that of untreated Ti6Al4V. (C) 2012 Elsevier B.V. All rights reserved.
