Purpose: The aim of this paper was investigated structure of sintered carbides WC-Co type and sialon tool ceramics with wear resistance ternary coatings TiBN type deposited by cathodes arc evaporation process (CAE-PVD). Design/methodology/approach: Observation of fracture and topography studied coatings were done by scanning electron microscope. Chemical composition was determine by energy dispersive spectrometry (EDS) method. Thin foils of substrates and coatings by transmission electron microscopy (TEM) was done. Phases composition analysis carried out by XRD and GIXRD method. Findings: The investigated PVD gradient coatings deposited by CAE-PVD method are demonstrating fine-grained structure. The TiN, TiB and TiB2 phases were found in coatings and Β-Si3N4 phase was found in sialon tool ceramics. Coating onto sialon tool ceramics reveal shallow pinhole while coating onto cemented carbide is without discontinuity. Research limitations/implications: In the future investigations will progress for mechanical properties, e.g. roughness, microhardness, adhesion strength and operating properties. Originality/value: In this work the influence of parameters deposited coatings by CAE-PVD technique on structure and phases composition the ternary TiBN gradient coatings were investigated.
