Abstract :Iron-based, nickel-based, and cobalt-based superalloys are the three types of superalloys utilized in high-temperature applications. Inconel 601 is a nickel-based superalloy that\'s used especially in aerospace, heat treatment, and gas turbine engine applications. In this study, thermal barrier coating (TBC) was applied approximately at 100, 200 and 300 μm ceramic top coating thicknesses and X-Ray Diffraction (XRD) analyzes were performed. NiCrAlY metallic powder was used for bond coating and 8% YSZ ceramic powder was used for ceramic top coating. Crystallite sizes and micro-strain values were calculated with the Scherrer Equation, Williamson-Hall method and Modified Scherrer (Monshi-Scherrer) equation of the compounds obtained at the peak points in XRD analysis.
