Thermal barrier coating (TBC) system is used in both aero engines and other gas turbines offer oxidation protection to super alloy substrate component. In the present work, it shows the ability of a new fabrication technique to develop rapidly new coating composition and microstructure. The compact powder were prepared by powder metallurgy method involving powder mixing and the bond coat was synthesized through the application of spark plasma sintering (SPS) at 1100°C, 1050°C and 1100°C to produce a fully dense 94%) Ni22Cr11Al bulk samples. The influence of sintering temperature on hardness of Ni22Cr11Al done by micro vickers hardness tester was investigated. And oxidation test were carried out at 1100°C for 20 hr, 40 hr and 100 hr. The resulting coat was characterised with Optical microscopy, Scanning electron microscopy (SEM) and X-ray diffraction (XRD). Micro XRD analysis after the oxidation test revealed the formation of protective oxides and non-protective oxides.
