Abstract

The fretting corrosion behavior and damage mechanism of Inconel 690TT in high-temperature pressurized (HTP) water and steam environments containing different dissolved oxygen levels were investigated. Adhesive wear in a steam environment significantly reduced wear volume and depth, and higher oxygen partial pressure in a steam environment was more conducive to internal oxidation. The formation of the glazed layer in a high-oxygen environment decreased wear volume, wear depth, and friction coefficient. The subsurface of wear scar under low-oxygen steam conditions exhibited complex layered nano-structure while relatively simple under high-oxygen steam conditions. Finally, the formation mechanisms of various layered nano-structures were revealed.

Inconel 690TT在不同溶解氧水平的水和蒸汽环境中的微动腐蚀行为及损伤机制

研究了含不同溶解氧的高温加压（HTP）水和蒸汽环境中Inconel 690TT的微动腐蚀行为和损伤机理。蒸汽环境下的黏着磨损显著降低了磨损体积和深度，蒸汽环境下较高的氧分压更有利于内部氧化。在高氧环境下形成的釉面层减少了磨损体积、磨损深度和摩擦系数。低氧蒸汽条件下磨损痕亚表面呈现复杂的层状纳米结构，而高氧蒸汽条件下磨损痕亚表面相对简单。最后，揭示了各种层状纳米结构的形成机理。
