“…As with the previous coating, the addition of aluminum and niobium increases the hardness and wear resistance, respectively, while providing greater impact toughness and heat resistance. Based on the previous studies [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25], coating thicknesses of 4-5 mm were assumed as optimal for turning of steels.…”

Abstract. This paper addresses the challenges of increasing the efficiency of the machining of austenitic stainless steels AISI 321 and S31600 by application of cutting tools with multilayer composite nano-structured coatings. The main mechanical properties and internal structures of the coatings under study (hardness, adhesion strength in the "coating-substrate" system) were investigated, and their chemical compositions were analyzed. The conducted research of tool life and nature of wear of carbide tools with the investigated coatings during turning of the above mentioned steels showed that the application of those coatings increases the tool life by up to 2.5 times. In addition, the use of a cutting tool with coatings allows machining at higher cutting speeds. It was also found that the use of a tool with multilayer composite nano-structured coating (Zr,Nb)N-(Zr,Al,Nb) N ensures better results compared with not only monolithic coating TiN, but also with nano-structured coatings Ti-TiN-(Ti,Al)N and (Zr,Nb)N-(Cr,Zr,Nb,Al)N. The mechanism of failure of the coatings under study was also investigated.

“…Additionally, a survey of coating research methods is presented by Tkadletz et al [11]. As a rule, with all the abundance of coating compositions, sometimes including six or more elements, coatings with simpler compositions are more widely used.…”

“…grained TiN base-layer, both deposited within one deposition run using chemical vapor deposition (CVD), are shown. [82] Using EBSD, crystal orientation mapping, phase imaging, determination of grain size distribution, and strain analysis can be performed. In contrast, the grain size of the TiB 2 layer decreases with increasing coating thickness.…”

REVIEWThis review features the potential of modern high spatial resolution methods in materials science and engineering by presenting a selection of scientific examples covering bulk materials, as well as hard coatings, semiconductors, and mesoporous thin films. Complementary techniques are employed to study microstructure and/or texture and stresses in multiphase Mo-, Al-, and Mg-base alloys, in several nitride-and boride-based hard coatings, in silicon, as well as in mesoporous silica films. Although far from being comprehensive, the chosen examples aim at underlining the importance of modern electron microscopy based methods and of scattering/diffraction techniques at large scale neutron and synchrotron radiation facilities for modern materials research. In addition, atom probe tomography, Raman scattering and atomic force microscopy are also highlighted.

“…On the one hand, the use of modifying coatings makes it possible to increase tool life, while on the other hand, that can significantly increase cutting modes and the cutting speed [1][2][3][4][5]. Coating thickness is an important indicator that significantly affects the performance properties of metal cutting tools.…”

This paper considers the influence of thickness of multilayered nano-structured coatings Ti-TiN-(TiCrAl)N and Zr-ZrN-(ZrCrNbAl)N on tool life of metal cutting tools at various cutting speeds (v c = 250, 300, 350 and 400 m·min −1 ). The paper investigates the basic mechanical parameters of coatings and the mechanism of coating failure in scratch testing depending on thickness of coating. Cutting tests were conducted in longitudinal turning of steel C45 with tools with the coatings under study of various thicknesses (3, 5, and 7 µm), with an uncoated tool and with a tool with a "reference" coating of TiAlN. The relationship of "cutting speed v c -tool life T" was built and investigated; and the mechanisms were found to determine the selection of the optimum coating thickness at various cutting speeds. Advantages of cutting tools with these coatings are especially obvious at high cutting speeds (in particular, v c = 400 m·min −1 ). If at lower cutting speeds, the longest tool life is shown by tools with thicker coatings (of about 7 µm), then with an increase in cutting speed (especially at v c = 400 m·min −1 ) the longest tool life is shown by tools with thinner coating (of about 3 µm).
