Fretting wear of alloy 690 tube mated with different materials in high temperature water

Fretting wear of alloy 690 steam generator heat exchange tube against different anti-vibration bar materials is studied in simulated secondary water conditions of pressurized water reactors (PWR). The results indicate that the wear mode of alloy 690 is largely dependent on the mating materials, and the material transfer during wear influences the corrosion resistance of alloy 690. The depth and volume of the wear scar on alloy 690 is the lowest...
