Thermal barrier coatings (TBC) are widely used to protect the structural components of gas/steam turbines in the energy and aerospace industries against aggressive operating conditions (environmental conditions such as high temperature, high pressure and oxidation/corrosion etc.). These coatings help prolong the life of components, reduce costs and ensure safe component operation. With the developing technology, the need for barrier coatings is constantly increasing. In this study, Nb additive CrYN film was coated on 4140 steel using the CFUBMS (Closed Field Unbalanced Magnetic Field Sputtering) technique. The specimens coated with Nb additive CrYN thin films were annealed at 400, 500, 600, 700 and 800 °C. Then, the structural and mechanical properties of the films were investigated. Microhardness and adhesion test were used to determine mechanical properties. Structural features were observed in X-ray diffraction (XRD). The critical load values of Nb additive CrYN thin films were analyzed by scratch tester.
