This thesis investigates the development of low friction and wear-resistant carbon nitride thin films for rolling components, particularly roller bearings, using various magnetron sputtering techniques. The research focuses on the synthesis of carbon nitride (CNx) thin films at low temperatures, exploring different sputtering methods like mid-frequency magnetron sputtering (MFMS), direct current magnetron sputtering (DCMS), and high power impulse magnetron sputtering (HiPIMS). The study examines how factors such as bias duty cycles, ion energy, and deposition techniques influence the mechanical properties, morphology, and tribological behavior of the films. The findings suggest that denser and homogeneous films exhibit superior wear resistance and mechanical strength, with the MFMS technique producing particularly promising results. The thesis is aimed at researchers and professionals in material science and engineering fields who are interested in advanced coatings for industrial applications.
