抄録

The fretting fatigue tests of Ti-6Al-4V were carried out using Cu-Ni plasma coated and as-received pads (un-coated pads). Fretting fatigue tests of Ti-6Al-4V, where Cu-Ni plasma coated and as-received pads were used, repeatedly were also carried out. The characterization of pads before and after testing were carried out in order to investigate the mechanism of fretting fatigue of Ti-6Al-4V in contact with the Cu-Ni plasma coated pad used. Cu-Ni plasma coating on the pads prolonged the fretting fatigue life of Ti-6Al-4V. The fretting fatigue life of Ti-6Al-4V decreased with repeated use of test when the Cu-Ni plasma coated pads. On the other hand, the opposite trend was observed when the as-received pads were repeatedly used. The surfaces of Cu-Ni plasma coated pads were smoother after testing than before testing due to the plastic deformation. On the other hand, the surface of as-received pads were rougher after testing than before testing.
