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 degree of these stresses is determined by contact loads, temperature in the contact area, and residual stresses in the coating structure [17][18][19][20]. The action of equivalent stresses at the elastic contact areas accompanied with the setting process leads to the cyclic nature of the thermal and mechanical stresses that affect the contact surfaces of the cutting tool resulting in fatigue crack propagation, and elastic-plastic deformation of the tool cutting wedge causes the formation of transverse cracks [21]. The highest equivalent stresses occur when carbonitride coatings are used rather than nitride coatings (e.g., TiCN and TiN, TiZrCN and TiZrN), which are characterized by smaller values of fracture toughness and higher coefficient of friction.…”

“…Cutting tools with functional coatings are increasingly used in industry, since they solve a range of complex tasks to improve the productivity of production processes of machining; however, they remain the weak component in the technological process of cutting and limits its development [1][2][3][4][5][6]. In this context, the challenge to improve compositions and structures of wear-resistant coatings for cutting tools, methods and technologies of their production is relevant and aimed at further improvement of the efficiency of machining.…”

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.

Hard and smooth coatings with high oxidation resistance and thermal stability are used for economical machining. In this regard, nc‐(Ti,Al)N/a‐Si3N4 films were sputtered on tungsten carbide cutting inserts and WC/Co samples by using an industrial CC800/9 high power pulse magnetron sputtering (HPPMS) coating unit. Coating composition and mechanical properties were investigated by scanning electron microscopy (EDS) and nano‐indentation. Hardness was about 36 GPa for a silicon content of about 9.6 at%. Optical emission spectroscopy (OES) was done to detect the ionization fraction of deposition species and to compare it to direct current (dc). Deposition rate of the HPPMS coatings was 1.6 times higher on areas positioned orthogonal to the target compared to dc sputtered coatings. Finally cutting performance was compared to a state‐of‐the‐art coating in turning HSS (high speed steel) under severe conditions. After the cutting tests SEM pictures were taken at the flank side of the cutting inserts to detect the wear. Cutting results show enhanced cutting performance due to the application of the HPPMS‐technology resulting in denser structure, higher hardness, smoother surface and better thickness uniformity compared to dc.
