Description
TiBN ternary coatings are of great industrial value, considering their prominent mechanical and tribological properties, such as super hardness, low intrinsic stress and high wear resistance. These coatings have been successfully applied to cutting tools, die-casting moulds, forging dies, aluminium extrusion dies, etc. Therefore, for these applications, the thermal stability and oxidation resistance of TiBN coatings will have a profound influence on the performance of the coated tools, moulds and dies during service. The TiBN coatings were deposited onto HSS substrates. The coatings were prepared by cathodic arc evaporation using the LARC® technology. The impact of various boron content on TiBN structure, thermal stability, oxidation resistance and presence of residual stresses inside the layers will be studied. With X-ray diffraction, TEM and SEM microscopy, the morphology, structure and phase composition of coatings were evaluated. XRD analysis was also employed for detection of phase changes in deposited TiBN coatings and residual stresses measurements as well.
