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 insert ignore into journalissuearticles values(TBC); was applied approximately at 100, 200 and 300 μm ceramic top coating thicknesses and X-Ray Diffraction insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(Monshi-Scherrer); equation of the compounds obtained at the peak points in XRD analysis.
