摘要

The effect of the interaction between corrosion and wear on the service behavior of IN617 superalloy after short-term aging treatment at 750 °C in marine is studied. The results indicate that the grain size of IN617 superalloy decreases, and the hardness of the aged IN617 superalloy increases after short-term aging treatment. The effect of the short-term aging treatment on the corrosion resistance of IN617 superalloy in simulated marine environment is not significant. However, due to the aged treatment, the grain sizes of the aged IN617 superalloy become finer, and their mass losses and wear scar sizes in the corrosion-wear experiment are significantly lower than those of the solid solution one. Moreover, the interaction between corrosion and wear is the main cause of mass loss in IN617 superalloy during the corrosion-wear experiment. As the applied potential rises, the aged IN617 superalloys suffered more severely in the corrosion-wear experiment.
