Abstract
To understand the role of rare earth elements in influencing high-temperature oxidation behavior of the Ni-based single crystal superalloy, a high Mo-containing nickel-based single crystal superalloy and the derivative alloy modified by Ce and Dy were designed. The results of oxidation tests conducted at 1100 °C indicated that do** 0.022 wt% Ce or 0.042 wt% Dy significantly improved the oxidation resistance of the alloy by reducing the oxide scale growth rate and enhancing the scale adhesion. The positive effects are probably because the doped trace of Dy or Ce can combine with O2− more quickly and reduce the oxygen contents on the oxide surface which decreases the oxidation rate. At the same time, it decreases the thickness of oxide scale which results in the reduction of the elastic strain energy and the weaker tendency to spallation of the oxide scale. But too high concentration of Dy or Ce was deleterious because its high oxidation rate results in much more defects which induce cracks easily.
