  • Received Date: November 01, 2007
  • ser surface melting (LSM)on the surface of Ni-Ti shape memory alloy (SMA)was fabricated with a continuous wave Nd-YAG laser.The fretting behavior of NiTi LSM layer was investigated with a SRV Ⅲ friction and wear tester.The surface morphologies and the component of wear debris were analy sed by scanning electron microscopy (SEM) and energy dispersive spectroscope (EDS).The wear depth was measured with a surface profiler, and the wear volume was also calculated.The results show that the friction coefficient and the wear volume of NiTi LSM are lower than those of NiTi alloy, laser surface melting improves the fretting wear resistance of NiTi alloy, the fretting wear mechanism of NiTi alloy is mainly grain abrasive and oxidation, and the fretting wear mechanism of NiTi LSM is fatigue flake mechanism and grain abrasive.
