This study aims to investigate the wear properties of innovative TiCrNb-hBN coatings under high temperature (450°C) condition. TiCrNb-hBN thin films wear deposited on the 1.2714 hot work tool steel by high power impulse closed field unbalanced magnetron sputtering PVD method. Scanning electron microscope and X-Ray diffraction analyses were performed to structural investigations. The grain size of the produced coatings was determined using the data obtained from the XRD analysis in the Scherrer formula. Nanohardness and scratch tests were used to determine the mechanical properties of the coatings. The scratches formed on the surface as a result of the scratch test were characterized using an optical microscope. The nanohardness of 1.2714 steel was enhanced thanks to the this newly designed surface coatings, and the highest nano-hardness value was determined as 16,91 GPa, which was 400% superior than base material. The wear performance of the coatings was determined with a ball on disc type tribometer under high temperature condition. As a result of the wear test, the effect of the h-BN structure, which is known to have a lubricating effect at high temperatures, has been clearly demonstrated. The friction coefficient and specific wear rate of the coating layer with the highest hardness and scratch resistance were also the most successful. Thanks to this paper, the performance of 1.2714 hot work tool steel, which is frequently employed in high temperature applications in the industry, has been improved with an innovative coating layer and a unique study has been brought to the literature.
