Abstract

The study investigated the performance properties of a carbide tool with multilayer composite nano-structured Ti-TiCN-TiAlCN and Ti-TiCN-TiAlCrCN coatings, obtained by filtered cathodic vacuum-arc deposition (FCVAD). The study considered the structure of these coatings and their basic mechanical properties (hardness, strength of adhesion bond to substrate, and elemental composition). The study included cutting tests of carbide tools with those coatings in comparison with uncoated tools and tools with Ti-TiN coating. The tests were carried out during the turning of steel C45 at various cutting speeds (300, 350, and 400 m/min). The study included research of the kinematics of tool wear and the nature of cracking in the structure of coatings. Diffusion processes in the system of substrate-coating tool material during machining were also studied.
