Abstract

Tensile behavior of Pt-aluminide (PtAl) coating with and without a middle NiRe layer on a Ni₃Al-based single crystal superalloy after different oxidation times were investigated at room temperature (RT) and 1100 °C. The results revealed that the existence of the NiRe layer not only improved the oxidation resistance of the coating, but also performed a significant inhibition of crack propagation, contributing to a superior ductility of the oxidized Re modified PtAl (PtReAl) coated specimen. The tensile and cracking behaviors of the coated specimens at RT and 1100 °C were discussed in detail.
