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
