Fretting Wear Behavior of Cu-Al Coating on Ti-6Al-4V Substrate under Various Conditions |
| 초록 |
Fretting wear and fretting fatigue are two commonly observed material damages when two contacting bodies with a clamping load are under the oscillatory motion. In this study, fretting wear damage of Cu–Al coating on titanium alloy, Ti–6Al–4V substrate was investigated under various contact conditions. Fretting tests were conducted with either no fatigue load or the maximum fatigue load of 300MPa and stress ratio of 0.1 on the substrate (specimen) under dry and wet conditions. Wet contact condition reduced frictional force during cycling as evidenced by the lower tangential force. Wear analysis using the accumulated dissipated energy approach did not show any effect of contact surface condition. In other words, the relationship between the accumulated dissipated energy and wear volume showed a linear relationship, and it was independent of loading and contact surface conditions as well as of the fretting regime. Further, the relationship between the wear depth and accumulated dissipated energy did not show any effect of loading and contact surface conditions as well as of the fretting regime up to instant when the maximum wear depth was equal to the coating thickness. |
