“…emphasized that the hardness of coatings improved with increased bias voltage. In related study, the reason for this was attributed on the increasing compressive stress by creating preferential regions on the substrate surface with enhanced bias voltage [29]. In a similar study, it was achieved to improve the hardness by increasing bias voltage used in the production of TiZrN coatings [21].…”

In this study, TiAlZrN layer was coated on AISI H13 substrate surface with variable substrate bias voltage, Zr target current, and ambient pressure deposition parameters by using closed field unbalanced magnetron sputtering (CFUBMS) technique. The main goal of this paper is to determine the effect percentages of these variable parameters on the properties of TiAlZrN coatings by Analysis of Variance (ANOVA). These coating properties include average grain size, thickness, hardness, adhesion strength and wear resistance. The numerical data obtained as a result of this study will shed light on the select of parameters which have a direct effect on coatings to the researchers who will work on this topic. The parameters used as variables in the deposition process were leveled with Taguchi experimental (33) design method. Average grain size and thickness of coatings were established by SEM images. The average grain sizes of coatings were between 290 and 440 nm and the most effective parameter was substrate bias voltage with 58.4 %. The hardness, adhesion strength and wear properties of the coatings were determined using micro hardness tester, scratch test and ball on disc wear device respectively. The maximum hardness of coatings was 1674 HV, while the wear resistance was increased by 37 times compared to the substrate material. The maximum adhesion strength value of the coatings was reached 56N. The superiority of the effect of substrate bias voltage on the hardness, adhesion strength and wear resistance of the coatings compared to other deposition parameters was again prominent (respectively 86.15%, 53.63% and 70.86%). Also, the hardness and wear resistance properties were found to be directly related to each other. The sample with the highest coating hardness also showed the highest wear resistance performance. In the sample with the lowest hardness, this situation found to be similar.

“…Small (below 10 nm) grain sizes of such materials and a considerable increasing of a volume content of inter faces allows one to achieve the unique properties (hardness, plasticity, wear, high temperatures, and corrosion resistance) [1][2][3][4][5][6]. The coating deposition by a vacuum arc discharge makes it possible to introduce the results of studies into the manufacture of products of various functionalities [7][8][9][10].…”

“…The structures and properties as well as the possibilities of thermal stabilization of the phase compositions of such alloyed condensates are poorly known for the present. But as a whole the above materials exhibit a higher hardness (up to 36-50 GPa) [5,6,8,17], elasticity (300-425 GPa) [3,8], and thermal stability [5]. Among these studies the research of Taiwan scientists [19] stands out, where the five component coatings (Zr-Ti-Cr-Nb)N exhibits a low hardness (2.5 GPa) and Young modulus (93 GPa), which is even below the values of the ZrTiCrNb (H = 4.7 GPa) target produced by arc melting according to the authors version.…”

“…One of the reasons for such a softness of the material is probably a high nitrogen concentration (about 47 at % at a flow of 8 cm 3 /min). However, this interpretation of the results leaves something to be discussed, as the nitrogen concentration is sufficient for the formation of a harder material [8,[22][23][24][25][26][27]. A complex of physical and mechanical properties of pure metals like zirconium, niobium, titanium, molybdenum, and chromium, allows us to assume that the investigation of vacuumplasma condensates based on the Zr-Ti-Cr-Nb system is advisable.…”

Abstract-Structure and properties of (Zr-Ti-Cr-Nb)N multicomponent nanostructured coatings fab ricated by a vacuum arc deposition have been investigated. It has been found that the coatings thickness attained 6.2 μm, hardness and indentation load that is responsible for the stress exceeding cohesion strength of coatings were H = 43.7 GPa and L c = 62.06 N, respectively. In coatings structures have been identified that consist of three interstitial phases having cubic, hexagonal, and tetragonal lattices. The nanocrystallites sizes were from 4 to 7.3 nm. The results of the SEM, TEM, EDS, and XRD analysis have been also considered.

“…At present, the most of the coatings widely used in industrial sphere are based on the TiN and (Ti,Al)N systems, as a rule, with the inclusion of additional elements, such as Cr, Mo, Y, Gf, Si, and others for the improvement of hardness, wear resistance, and heat resistance, which is very important [1][2][3][4][5][6][7][8][9][10]. Taking into account the fact that an enhancement of the cutting efficiency is an essential task of the modern manufacturing, while an increase in the cutting speed is a prevailing way to enhance the efficiency, the heat resistance is becoming an increasingly important property.…”

The paper presents the results of the investigation focused on the properties of the Cr,Mo-(Cr,Mo)N-(Cr,Mo,Al)N multilayered composite wear-resistant coating with a nanostructured wear-resistant layer. The nanostructure of the coating was investigated using transmission electron microscopy (TEM), the microhardness was measured, and the chemical composition was found. The cutting properties of a tool with the Cr,Mo-(Cr,Mo)N-(Cr,Mo,Al)N coating were studied during the turning of 09G2S silicon-manganese steel. It has been found that the use of a cutting tool with the Cr,Mo-(Cr,Mo)N-(Cr,Mo,Al)N coating reduces the flank wear rate by 1.65 times compared to an uncoated tool.
