Purpose: It has been demonstrated in the paper that deposition of the multilayer and gradient coatings with the PVD and CVD methods on sintered tool materials. Design/methodology/approach: TEM, SEM, scratch test, microhardness tests, roughness tests, cutting tests. Findings: It has been demonstrated in this work that deposition of the multilayer or gradient coatings with the PVD (Cathodic Arc Evaporation) or CVD process on tools made from nitride, oxide ceramics and cermets results in the increase of coatings’ hardness and improvement of their adhesion to the substrate, in comparison with the multiple-layer coatings deposited using the PVD/CVD methods on the same substrate materials, deciding improvement of the working properties of cutting tools coated with the TiN+gradient or multi(Ti,Al,Si)N+TiN system coatings, compared with coatings developed on the same sintered tool materials, but uncoated or coated with simple coatings. Practical implications: Pro-ecological dry cutting processes without the use of the cutting fluids and in the „Near-Net-Shape” technology. Originality/value: In the paper the research of multilayer and gradient TiN+(Ti,Al,Si)N+TiN nanocrystalline coatings deposited in the PVD method on sintered tool materials carried out in order to improve the tool cutting properties.
