Purpose: Investigation of the structure and corrosion resistance of the TiN, TiN+multiTiAlSiN+TiN, TiN+TiAlSiN+TiN, TiN+TiAlSiN+AlSiTiN coatings deposited by PVD process and TiCN+TiN, TiCN+Al2O3+TiN, TiC+TiCN+Al2O3+TiN, TiN+Al2O3 coatings deposited by CVD process. Design/methodology/approach: The metallographic examinations (SEM), the examinations of thin foils (TEM), investigation of the electrochemical corrosion behavior of the samples in a PGP 201 Potentiostat/Galvanostat, in a three-electrode chamber was done. Findings: Corrosion current density - corrosion rate - was determined by analysis of the potentiodynamic polarization curves. Relationships of structure and corrosion properties has been presented. Research limitations/implications: Implication of the investigation results are researches of corrosion properties in high temperature. Practical implications: Employment of the surface treatment technology for tools, made from tool materials, with the PVD and CVD methods, to obtain the high wear resistant coatings, makes it possible to improve the properties of these materials in the dry-cutting conditions, by - among others - decreasing their friction coefficient, microhardness increase, improvement of the tribological contact conditions in the cutting tool-machined workpiece zone, and also to improve protection against the adhesion and diffusion wear. Originality/value: Original system of substrate/coating compositions.
