Abstract
Background The significance of multi-graded thin film coatings finds its devastating relevance in tribological applications due to their unique properties of friction and wear. This research aims to synthesize and characterize the multi-graded Ta/TaN thin film coatings on AISI 52100 steel, employing the high-power impulse magnetron sputtering technique. Methods The investigation includes the microstructure, coating thickness, elemental composition, microhardness, and tribological performance using scanning electron microscope (SEM), energy-dispersive x-ray spectroscopy (EDS), x-Ray diffraction analysis (XRD), microhardness tester, and pin-on-disc tester, respectively. Results Based on this systematic study, a noticeable reduction in the coefficient of friction was obtained due to the improved adhesion value exhibited by the multi-graded coating on the substrate. Conclusions The overall findings highlight the potential suitability of the multi-graded Ta/TaN thin film coating within the field of tribological applications.
