Purpose: The main aim of this research was an investigation of both the coatings structure and mechanical properties deposited by the cathode arc evaporation physical vapor deposition (CAE-PVD) on sintered carbides and sialon tool ceramics substrates. Design/methodology/approach: The (Ti,Al)N and (Al,Ti)N coatings were investigated. Microstructure was characterized using the scanning and transmission electron microscopy. Phases composition analysis was carried out by the XRD and GIXRD method. Investigation of surface roughness was done. The mechanical properties were determined on basis of following research: a measurement of hardness using Vickres’s method, a measurement of roughness, adhesion using Scratch Test method. The cutting ability was defined on basis of technological cutting trials. Findings: The investigations made by use of the glow discharge optical emission spectrometer indicate the existence of the transition zone between the substrate material and the coating. The results shows that (Al,Ti)N coating presents good adhesion onto booth substrates and (Ti,Al)N coating presents good adhesion onto sintered carbides substrate. All the coatings demonstrate a high hardness. Research limitations/implications: The good adhesion (Al,Ti)N coating to sialon substrate is connecting with the same type of bonding in coat and sialon substrate. Originality/value: The good properties of the PVD gradient coatings make them suitable for various engineering and industrial applications.
