Purpose: Investigation of the Al2O3+TiC type oxide tool ceramics and cemented carbides with the multicomponent (Ti, Al)N and gradient Ti(C, N) coatings deposited with use of the cathodic arc evaporation CAE-PVD method. Design/methodology/approach: SEM, confocal microscopy, X-ray qualitative microanalysis of elements, X-ray qualitative phase analysis. Findings: It was stated that investigated materials have a dense, compact structure and their fracture surface topography attests their high brittleness, characteristic especially for the oxide ceramic materials. The coatings were put down uniformly onto the investigated substrate materials. They have a columnar, fine-graded structure. Practical implications: Pro-ecological dry cutting processes without the use of the cutting fluids and in the "Near-Net-Shape" technology. Originality/value: Application of multicomponent (Ti, Al)N and gradient Ti(C, N) types of coatings onto sintered tool materials in order to improve cutting properties of the tools.
