“…Although the quest for superhard coatings continues [1][2][3][4], they have limited use without appropriate toughness. It is the less-hard, and hence tougher coatings, that find use for most safety-critical applications such as medical devices, engine components and high speed cutting tools, where catastrophic failure is not tolerated.…”

“…Hybrid material systems consisting of one hard and one relatively soft phase have attracted considerable attention in the design of hard, yet tough, coatings [3][4][5][6][7][8]. For example, M 1 N-M 2 systems, where M 1 N represents hard transition metal nitrides e.g.…”

“…CrN-Ni coatings can be prepared relatively easily by reactive magnetron sputtering using a Ni-Cr alloy target in a nitrogen reactive gas environment [3,4]. Due to the low permeability of Ni to nitrogen [3,9], chromium tends to form stable nitrides (CrN and Cr 2 N) more readily [3,6,9].…”

“…Due to the low permeability of Ni to nitrogen [3,9], chromium tends to form stable nitrides (CrN and Cr 2 N) more readily [3,6,9]. In addition, Ni is insoluble in stoichiometric CrN [3,9]. It has been shown that the Ni content influences the coating hardness [3,4].…”

CrN is one of the most important transition metal nitrides, used as protective and anti-wear coating in modern engineering applications. However, CrN coatings are typically brittle and susceptible to catastrophic failure. In this paper, CrNiN coatings with differing Ni contents were deposited on tool steel substrates using a closed field unbalanced magnetron sputtering system. The effects of Ni addition on the microstructure and mechanical characteristics of CrN thin films were studied by combining nanoindentation tests with cross-sectional transmission electron microscopy. A columnar structure was observed in the CrN coating. With an increase in Ni content, the resultant columnar grains exhibited a high aspect ratio. Ni additions to CrN were

Atomic structure, adhesion energy, and electronic properties of the bonding nature at CrN(200)/Ni(111) interfacial region are studied by first‐principle calculations based on density functional theory (DFT). A new method for building the heterostructure of CrN(200)/Ni(111) is proposed to solve the large lattice mismatching between CrN(200) and Ni(111) slab. Three models (OT, ST, and TL) with different interface distance are built up, and the total energy for each of them is calculated. Comparing with other stacking sequence, TL sites with 1.9‐Å spacing at the interfacial region shows the biggest value of adhesion energy after geometry relaxation. Furthermore, the contour of charge density, partial charge density of states, and Bader charge values of the TL sites with 1.9‐Å spacing are plotted out and calculated. Results indicate that covalency bonding between Ni and N ions and metallic bonding between Ni and Cr atoms are formed at the interfacial region.

Chromium‐based coatings have been of interest to researchers for the last two decades because of their extraordinary properties like high hardness, high wear, and corrosion resistance properties. However, it is in practice and research to increase the properties of Cr‐based coatings for high‐temperature applications. Numerous dopants like silicon (Si), titanium (Ti), vanadium (V), aluminum (Al), and zirconium (Zr) have been used together with Cr to achieve enhanced properties. The plasma‐based sputtering process is one of the popular and reliable techniques to deposit thin film coatings. The substrate material, processed gas and pressure, substrate temperature, film thickness, and so on also play a significant role in varying the properties and microstructure of the deposited film. Several researchers have deposited Cr/CrN‐based thin films via the chemical vapor deposition technique (CVD) and physical vapor deposition technique (PVD) to study their properties and behavior at room temperature as well as for high‐temperature applications. This work reflects the review of work done to deposit Cr/CrN‐based coatings deposited via PVD: more specifically sputtering technique. The effect of doping in the CrN matrix and variation in sputtering parameters on the properties of CrN‐based coatings have also been studied.
