- Abstract
Fretting wear tests of TP31 6H steels under different environments (air/water at room temperature9 air/liquid sodium at 450 °C) were carried out by a self-made fretting wear test rig with the contact configuration of tube-on-rod. After tests, the worn surfaces were examined by a super depth field microscope, 3D optical microscope, SEM(scanning electron microscope) and EDS (energy dispersive spectroscopy) to obtain information on wear morphology, volume and surface chemical compositions. The results show that the highest wear rate of TP31 6H steels in 450 °C liquid sodium and the lowest wear rate is in room temperature water. The wear mechanism of TP31 6H steels in 4 environments is different. Delamination and oxidative wear are the main wear mechanism in air, and oxidation intensifies with the increase of temperature, while the abrasive wear is dominant in water. The synergistic effect of wear and corrosion is found in liquid sodium at 450 °C.
