The Pt-Al coating is a vital section of aero-engine power blades that can improve the operating temperature of the blade. The blade is subjected to axial tensile stress during operation. Both the oxidation of the Pt-Al coating and the microstructure evolution caused by the element diffusion between the coating and the matrix at high temperatures affect the service performance of the blade. However, the specific mechanisms remain unclear. In this work the effect of Pt-Al coating on the tensile properties of a DD413 alloy was studied. SEM and TEM were used to compare the tensile properties of the uncoated and Pt-Al-coated samples, respectively, at 760 and 980oC. Lower yield strength was detected in Pt-Al-coated samples than that in uncoated samples at 760 and 980oC. The different crack initiation modes and deformation mechanisms of Pt-Al coating at 760 and 980oC mainly result from the ductile to brittle transition temperature (DBTT). At high temperatures, the transition from β to γ′ is conducive to the dislocation slip, which leads to the plastic deformation of the Pt-Al coating. The increase in the tensile strength of the Pt-Al layer above DBTT can be attributed to the solidified solution-strengthening effect of Pt in β-NiAl.
