© 2018 Elsevier B.V. The paper deals with the wear dynamics shown by carbide tools with multilayer composite nanostructured coatings of various compositions. The investigation involved coatings based on nitrides of such metals as Ti, Zr, Cr, Nb, and Al with three-layer architecture, including adhesion, transition, and wear-resistant layers. The thickness of the coatings was about 4 µm. There was a series of cutting tests involving tools with the coatings under study in the turning of AISI 1045 steel at vc = 200, 250, 300, and 350 m/min. The comparative studies were conducted to investigate wear process patterns for tools with the coatings under study and for uncoated tools and tools with TiN reference coatings, depending on the cutting speed. In particular, the study considered the intensity and specific features of crater formation on the tool rake face. In particular, it was found that an increase in cutting speed led to more active movement of a crater away from the cutting edge, while at lower cutting speeds, a crater developed evenly. Diffusion and oxidation processes were registered and studied at the boundary between the coating and the material being machined. The use of the coatings under study makes it possible to significantly increase the cutting speed, while the optimal composition of the coating depends on the applied cutting speed.
