Abstract:The fretting wear behavior under gross-slip of Ti-6Al-4V alloy samples with as- received, single shot peening, and shot peening followed by plasma spraying of CuNiIn coating, is studied on. The results show that, single shot peening cannot improve fretting wear resistance of titanium alloy, but promote the forma-tion of third-body consisted of compact zone and debris, operating in steady state. The combined treatment of shot peening followed by plasma spraying can reduce the wear volume, and its worn surface generates third-body from the accumulation of lots ifne debris, improving Ti-6Al-4V alloy fretting wear property.
