“…Binary and ternary metal nitrides, such as CrN and (Cr,Al)N deposited by physical vapor deposition (PVD) have been investigated as protective coatings for different technical applications . During their application on the surface of tools for plastic processing, these coating materials are subjected to several normal or lateral loads, for example, by hard fillers existing in the plastic melts .…”

Investigations on Mechanical and Tribological Behavior of dcMS/HPPMS CrN and (Cr,Al)N Hard Coatings Using Nanoscratch Technique

et al. 2017

In this paper, interfacial adhesion strength and tribological behavior of systems, consisting of CrN and (Cr,Al)N coatings and AISI 420 steel substrate are investigated. The coatings are deposited using a hybrid technology consisting of direct current and high power pulse magnetron sputtering dcMS/HPPMS. Conventional Rockwell and scratch tests as well as nanoscratch analyses are performed. For the nanoscratch tests, a Berkovich and a conical indenters are used. Damage mechanisms are analyzed using Scanning Electron Microscopy (SEM) and explained by the plastic work from the nanoindentation tests. Investigations show a stronger interfacial adhesion strength and a higher abrasion resistance of the system AISI 420/(Cr,Al)N compared to the AISI 420/CrN.

“…TiVCN as well as TiVN hard coatings can be the other potential wear resistance coatings which make it can replace the conventional TiN coatings. During decades, ternary transition metal nitrides such as (Ti,Al)N and (Cr,Al)N have been attracting great interest for applications as hard protective coating materials due to their high hardness, good wear resistance and excellent corrosion protection [1][2][3][4][5][6]. Extensively investigations have extended to multilayered TiAlN/CrAlN [7][8] and additional metal dope [9][10] ternary transition metal nitrides.…”

Currently, TiVN and TiVCN coating are not prevailing in the literature. Only a few publications are revealed with basic properties. In this study, the TiVN and TiVCN coatings are deposited by using cathodic arc deposition system with Ti and TiV alloy dual targets. The result shows that V and C addition lead to the increase of surface roughness by droplets deposition in the TiVN and TiVCN coatings as compared to TiN. However, grain size of the TiVN and TiVCN coatings is obviously reduced by adding the V and C in the coating. The highest hardness and the best wear resistance are obtained for the TiVCN coating. Thermal stability of the TiVCN coatings is affected by the C addition resulting in severe oxidation.

“…Such behavior motivates us to use some artificial viscous term as explain in [43] to improve the convergence. Images from scanning electron microscopy www.gamm-mitteilungen.org (SEM) show that a columnar grain morphology is observed for a certain range of process parameters [20,44]. The grain morphology depends on various conditions like the temperature and pressure at which the deposition takes place.…”

Cohesize zone‐based modeling of nano‐coating layers for the purpose of establishing process signatures

et al. 2017

View full text Add to dashboard Cite

The purpose of this work is to establish the notion of process signatures in the context of manufacture processing. In this context we provide an overview of selected computational approaches which are capable of resolving the basic features of non-linear heterogeneous microstructures and process related boundary and loading conditions. As an example, the cohesize zone element method is employed to predict the state of damage and fracture in coated systems. The latter are composed of CrN-or AlN-based protective coating layers and steel-based substrates. The state of damage and fracture is simulated for nano-indentation tests and discussed at different deformation stages. Furthermore, the influence of residual stresses within the polygrain microstructure on the evolution of damage and fracture is analyzed. Lastly, future developments and computational challenges are discussed.
