Purpose: Comprehensive structure and properties investigation results of the multilayer, multi-component, gradient PVD and CVD coatings developed on the Si3N4 nitride tool ceramics substrate are presented in the paper. Design/methodology/approach: The detailed results are presented of examinations carried out on the transmission and scanning electron microscopes, as well as of the mechanical properties and tribological tests of the investigated coatings. Findings: The research carried out proved that depositing the hard, anti wear, multilayer coatings based on the Al2O3 and TiN layers onto the Si3N4 nitride tool ceramics with the PVD method results in obtaining better functional properties like extension of the cutting tool life, than in case of the uncoated nitride ceramics or coated with the PVD coatings and some CVD ones. Research limitations/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 coatings deposited in the PVD and CVD methods on sintered tool materials carried out in order to improve the tool cutting properties.
