Effect of temperature on tribo-oxide formation and the fretting wear and friction behavior of zirconium and nickel-based alloys

Fretting wear damage in nuclear power plants is a safety and economic concern. Therefore, understanding the effect of operating conditions on the wear mechanism is essential for optimum design. Fretting tests were performed on a nickel-based alloy 718 against a zirconium alloy in the range 25 °C
