%X The wear performance of Ti6Al4V alloy for clinical usage was modified by dual--ion implantation technique. The samples were implanted firstly with silver ions at a dose of 1.0×1017 cm-2, then with tantalum ions at a dose of 1.5×1017 cm-2. Nanoindenter instrument was used to measure the variation of hardness with displacement into surface of sample, and multi--functional tribological tester was used to investigate the wear and tribological property. Phase constitution in the surface layer of Ti6Al4V alloy was characterized by glancing angle X--ray diffraction (GAXRD), the X--ray photoelectron spectroscopy was used to analyze the chemical states of elements in the surface layer of sample. The results show that the worn area of Ag+Ta dual--ion--implanted Ti6Al4V alloy is decreased by 77\% compared with untreated alloy. The improvement of the wear property is related to the increase of hardness, long holding time of low friction coefficient and solid solution strengthening induced by Ag and Ta.
