“…The phase composition of coatings was investigated by X-ray diffraction analysis using DRON-4 system with Cu-K α radiation (0.154 nm) according to the Bragg-Brentano scheme. A graphite monochromator was used to monochromatize radiation [15]. It was installed in a secondary beam (in front of the detector).…”

The effect of the MeN (Me-Cr, Mo, Zr) layer composition in multi-period vacuum-arc (TiAlSi) N / MeN coatings with a nanoscale layer thickness on the predominant orientation of crystallite growth in layer s and hardness was studied. It was found that phases with a cubic crystal lattice (structural type NaCl) in the layers of all types (TiAlSi)N/MeN coatings are formed, although for the MoN phase under equilibrium conditions a hexagonal crystal lattice is preferred. The interrelation between the structure of MeN and (TiAlSi)N layers is revealed, as well as the effect of the structural state on the coating hardness. Defining influence of the MeN layer on the formation of three structural states types was found: with a preferential crystallite growth with the texture axis [111]; with the texture axis [100]; the formation of a non-textured state. The highest hardness of 47.8 GPa was achieved in the (TiAlSi)N/ZrN multilayer coating with the texture axis [111].

“…In most works, ion-plasma (magnetron-type) sputtering is used to produce nitride coatings of the Ti-Al-Si-N system [14]. At the same time, a mixture of Ar/N2 gases is used as the atomizing atmosphere [15]. In this case, with a silicon content of less than 8 at.…”

“…For example, in the works of some authors, before coating the tool of high-speed steel is proposed to form a transition layer by ion implantation or laser treatment. The authors note a significant increase in tool life with duplex treatment compared with coated tools [19][20][21][22][23][24][25]. However, the most promising and cost-effective is the technology of duplex surface treatment of cutting tools of high-speed steels when the formation of the transition layer by ion nitriding and subsequent application of the wearresistant coating are performed in a single technological cycle [26][27][28][29][30][31][32][33][34].…”

The paper presents a series of experimental results for assessing the effect of duplex vacuum-plasma processing as sequential ion nitriding and coating (Nb–Ti–Al–V) N on the characteristics of the surface layer and the wear rate of complex profile tools as herringbone broaches and gear-shaping cutters from high-speed steels powder during machining a heat-resistant nickel-based alloy. The rational duplex processing modes for each type of multi-profile cutting tool under investigation were established. Tests of the tool after duplex processing under conditions close to those encountered in production showed an increase in the operational durability of herringbone broaches and gear-shaping cutters up to two times in comparison with the original tool.

“…The performance of such coatings can be further improved by doping a third metal or nonmetal element into the CrN-based coatings, such as Al [3,9], Mo [10], Zr [11], Cu [12], C [13], Si [14] and Al-Si [15,16] elements. These elements have all been previously used to modify the structures and properties of the CrN coatings.…”

Microstructure, Mechanical, Oxidation and Corrosion Properties of the Cr-Al-Si-N Coatings Deposited by a Hybrid Sputtering System

et al. 2017

CrN and Cr-Al-Si-N coatings were deposited on SUS304 and Si-wafers by a hybrid coating system. The Cr and Al-Si target were connected to the cathode arc ion plating (AIP) and high power impulse magnetron sputtering (HiPIMS), respectively. Various Al and Si contents in the coatings were obtained by changing the power of Al-Si target from 0 to 1 kW. The results demonstrated a face-centered cubic structure in all of the coatings. With increasing Al-Si target power, both the density and mean diameter of the macroparticles on the coating surface declined. As Al and Si contents increased, the microstructure of the Cr-Al-Si-N coatings evolved from a dense column structure, to a finer grain column structure, and then to a compact granular-like structure. The hardness of the coatings increased from 21.5 GPa for the pure CrN coating, to a maximum value of~27 GPa for the Cr-Al-Si-N coating deposited at 0.4 kW, which was mainly attributed to the solid solution strengthening and increased residual stress. The addition of Al and Si contents led to enhanced wear resistance against alumina balls at both room and elevated temperatures. Meanwhile, the Cr-Al-Si-N coatings also exhibited an excellent resistance to high-temperature oxidation at 800 and 1000 • C, and improved corrosion resistance, as compared with CrN coatings.
