Purpose: Investigation of structure and properties of the Al2O3 based Al2O3+ZrO2, Al2O3+TiC and Al2O3+SiC(w) type based oxide tool ceramics coated with the anti-wear mono- and multilayers of the TiN, TiAlN, TiN+TiAlSiN+TiN, TiN+multiAiAlSiN+TiN and TiN+TiAlSiN+AlSiTiN types in the cathode arc evaporation CAE-PVD and with the multilayers of the TiCN+TiN and TiN+Al2O3 types obtained in the chemical deposition from the gas phase CVD process. Design/methodology/approach: The investigations were carried out on the multi-point inserts made from the Al2O3+ZrO2, Al2O3+TiC, Al2O3+SiC(W) ceramics uncoated, coated in the PVD and CVD processes with thin coatings; observations of the investigated coatings' structures were carried out on the transverse fractures on the scanning electron microscope; the diffraction examinations and examinations of thin foils were made on the transmission electron microscope; the measurements of textures and phase composition were made; the macro-stress values were calculated; tribological tests were carried out on the "pin-on-disk" tester; the microhardness and adhesion tests of coatings were made; cutting ability of the investigated materials was determined basing on the technological continuous cutting tests. Findings: It has been demonstrated that the creation of the developed coatings by the use of the PVD and CVD methods on oxide ceramic tool materials causes the increase of coatings hardness and allows to improve application features of multi point cutting tools for high speed machining, tools for fine cutting coated with them and dry cutting without using the cutting fluids in comparison to the multi point cutting tools produced from the same uncoated materials. Practical implications: Putting down the anti-wear coatings onto the oxide ceramic tool materials is justified and the composite tool materials developed in this way may have the important application significance in the industry for cutting tools. Originality/value: Comparison of the wide range of modern oxide tool ceramics with wide unique set of PVD and CVD coatings.
