“…The coatings retain an appreciably high viscosity because they dissipate the brittle fracture energy at the inter-grain and interlayer boundaries [15]. The high hardness and resistance to plastic deformation of these type nanolayered composite coatings are determined by the increased strength of their adhesion to various substrates compared to that of coatings without a multilayered structure [16].…”

“…Coatings may have multiple physical purposes; on the one hand, the coating in spite of its tiny thickness (few micrometers), improves substrate properties such as surface hardness, physical-chemical passivity towards workpiece material, antifriction and thermal insulation. On the other hand, during the cutting process, the coating transforms the contact characteristics such as adhesion interaction, friction and inter-diffusion between workpiece and tool materials [1,3,8,[13][14][15][16]. The reduction of these characteristics allows lowering stresses (normal and shear), frictional heat capacity and thermal stresses acting at the contact areas of tool.…”

In coated tools, the grain boundaries and coating layers are areas of intense energy dissipation, which hardens the coating material by increasing its toughness and its resistance to the formation and development of cracks. An increase in the efficiency of the coatings was achieved by applying nano-dispersed multilayer composite structure. This paper proposes using nano-scale multilayer composite coating based on TiN-CrN compound to improve thermal stability, where, barrier layers based on ZrNbN have been introduced. The ZrNbN barrier does not interact with TiN and CrN at temperatures around 1000°C. The influence of process parameters of the filtered cathodic vacuum arc deposition on the composition, structure and properties of the coatings based on variation of TiAlN-ZrNbN-CrN was analyzed. The results presented here show that the hardness of the developed coatings was as high as 38 GPa. Subsequently, the carbide tools used in this study with the new coatings had an increased lifetime of 1.5-2.0 times compared to tools with commercial coatings. The coated tools were tested in turning and milling of steels, nickel and titanium alloys.

“…The design idea is to enrich CrN individual layer by the addition of silicon from a previously studied CrN/ZrN multilayer system. [13] This study is devoted to forward the understanding of the connection between the multilayer modulation periodicity and their microstructure and properties in the new multilayer system. Additionally, the tribological behaviors of the multilayers with different modulation periodicities have been concerned with a view to understand the underlying mechanism responsible for the improvement of wear resistance in this kind of system.…”

In this study, CrSiN/ZrN multilayer coatings were prepared by a reactive magnetron sputtering system. The evolution of their microstructure, mechanical, and tribological properties as a function of the multilayer modulation period was studied. The results showed that the multilayers had a good modulation structure. CrSiN and ZrN individual layer in the multilayers were “amorphous‐like” and amorphous structure, respectively.

Abstract. The paper considers the concept of a multi-layer architecture of the coating in which each layer has a predetermined functionality. Latest generation of coatings with multi-layered architecture for cutting tools secure a dual nature of the coating, in which coatings should not only improve the mechanical and physical characteristics of the cutting tool material, but also reduce the thermo-mechanical effect on the cutting tool determining wear intensity. Here are presented the results of the development of combined methods of forming multi-layer coatings with improved properties. Combined method of forming coatings using a pulsed laser allowed reducing excessively high levels of compressive residual stress and increasing micro hardness of the multilayered coatings. The results in testing coated HSS tools showed that the use of additional pulse of laser processing increases tool life up to 3 times. Using filtered cathodic vacuum arc deposition for the generation of multilayer coatings based on TiAlN compound has increased the wear-resistance of carbide tools by 2 fold compared with tool life of cutting tool with commercial TiN coatings. The aim of this study was to develop an innovative methodological approach to the deposition of multilayer coatings for cutting tools with functional architectural selection, properties and parameters of the coating based on sound knowledge of coating failure in machining process.
