Harbin Institute of Technology, Harbin 150001, China）Abstract: The modified layers by O2-PBII technology on Ti6Al4V alloy surface were studied using X-ray photoelectron spectroscopy. The negative pulse voltage of 10, 20, 30 kV was applied to the sample, which was mounted on an oil-cooled sample holder. The results show that the thickness of the oxide layer increases with increasing implanted ion energy.
