“…The formation of the α-Mo phase can be explained by the dependence of the coat nitrogen content on nitrogen pressure. It has been shown that in coatings formed at sure 9.33 × 10 −2 Pa, the nitrogen content is nearly two times lower than in coatings duced at a higher pressure, 0.4 Pa [55].…”

This paper presents the results of a study on the preparation and characterization of a Cr-DND/MoN detonation chromium-nanodiamond coating deposited on cemented tungsten carbide (WC–3 wt.% Co) mill blades using Arc-PVD and electrodeposition methods. The physical and mechanical characteristics of the coatings were investigated by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), XRD analysis, Raman spectroscopy, micro-identification, and scratch test (evaluation of the coating adhesion). It was shown that the Cr-DND/MoN coating consists of successive layers of Cr-DND (top), Cu (middle) and MoN (bottom) with separate phases of γ-Mo2N, α-Mo, α-Cu, Cr-DND and nanodiamonds. The Cr-DND composite electrochemical coating (CEC) was deposited from the conventional chromium plating electrolyte with the addition of nanodiamonds. The copper interlayer was deposited by the Arc-PVD method on the surface of the MoN coating to improve the adhesion strength of the Cr-DND CEC. The coating showed an optimum microhardness of about 14 ± 1 GPa and good adhesion with a critical load Lc of about 93 N. In addition to the expected experimental results, the coating has high wear resistance, confirmed by scratch tests.

“…Therefore, repetition of this process many times allowed obtaining multilayer TiN/ZrN coatings. The pressure of the nitrogen in a chamber (P N ), the bias voltage applied to the substrate (U b ) and the deposition time (t) were the key parameters that influenced properties and structure of the vacuum-arc coatings [121,122].…”

Nanocomposite Multilayer Binary Nitride Coatings Based on Transition and Refractory Metals: Structure and Properties

2019

One area of constant interest in many fields of industry is development of functional multilayer coatings that possess excellent performance characteristics. That is why in our brief review the results of studies of structure and properties of multilayer structures based on binary nitrides of transition or refractory metals obtained by various physical-vapor deposition (PVD) techniques are presented. The influence of substrate temperature, substrate bias voltage, bilayer thickness and interface boundaries on the structure of coatings and their properties, such as hardness, plasticity, wear and corrosion resistance, are discussed in detail. This review may be useful for students and growing community of researchers interested in the synthesis-structure-properties relationship in multilayer coatings based on metal nitrides.

Complex studies of the formation of the superhard state in the TiZrHfNbTaYN vacuum arc high entropy coating were carried out. Based on the approach of the structural surface engineering, the regularities of the formation of the triads composition-structure-physico mechanical properties depend ing on the supplied potential displacement are established. It is shown that the increase of U b at the forma tion of a coating leads to a decrease of the relative content of a light (Ti) and increase of a heavy (Ta, Hf) metal components, which is determined by radiationally stimulated processes in a near surface region at the deposition. The formation of the single phase state (based on the fcc of metal lattice) in the range U b from-50 to-250 V and revealed the formation of the preferred orientation of the crystallites with the axis [111], which is perpendicular to the growth plane. The increase of the perfection of the texture with the [111] axis with increasing U b is accompanied with an increase of the coatings hardness, which makes it possible to achieve the superhard state (H = 40.2 GPa) at U b =-250 V.
