“…Till date, the effect of combining Ni & Cr has not been studied adequately. The development of CrNiN thin film was carried out using unbalanced magnetron sputtering (closed field) for the components critical for safety [36], magnetic layers [37] and for applications related to cutting tools [38]. However, scarce literature is available, comparing mechanical performance of the single and gradient layer (Ni, Cr) N ternary layer deposited on the mild steel substrate.…”

Mild Steel (MS) is considered as the most widely employed engineering material, which is primarily being used in an automotive industry. Several parts including fuel system, outer and body panel, trims, chassis exhaust, along with many other parts are made up of MS. The driving force behind versatility of MS is its unique set of characteristics. However, the issues arise when its tribological degradation occur that creating problems in service conditions. The best solution for this problem is to coat the mild steel with transition metal-based nitride coatings such as, Ni and Cr. Insufficient Literature is available related to the mechanical performance of single/gradient layer (Ni, Cr) N ternary coating on mild steel substrate. Current review focuses on the characteristics of the coatings that are deposited through two different deposition techniques; electrodeposition and magnetron sputtering. The studied coatings materials are nitrides of nickel and chromium, deposited in several layers. Furthermore, the structural and mechanical properties of these coatings have been compared.

“…Until now, quite few authors have investigated the effect of combining the chromium and nickel phase together. Closed field unbalanced magnetron sputtering system has been utilised to develop CrNiN thin films for safety critical components, 12 magnetic films 13 and for cutting tools applications 14 . However, so far literature related to the comparison of mechanical properties exhibited by single and gradient layer (Cr, Ni) N ternary coating on mild steel is unavailable.…”

Ternary single and gradient layer (Cr, Ni) N thin films were deposited on the mild steel substrate by unbalanced magnetron sputtering technique in order to evaluate mechanical properties for machine tools and automotive applications. Microstructure, chemical composition, surface morphology and phase analysis were carried out using field emission scanning electron microscopy, energy dispersive X-ray spectroscopy, atomic force microscopy and X-ray diffraction, respectively. Both single and gradient layer of (Cr, Ni) N coatings show a significant increment in mechanical properties such as hardness, adhesion strength and surface roughness along with the reduction of friction coefficient. Mechanical tests revealed that the hardness of the gradient layer increased up to 3.1 times due to the formation of Cr 2 N and Ni phase whereas single layer showed the least friction. Single layer CrNiN layer exhibited 27.2% less surface roughness (R a ) in comparison with gradient layer. High values of surface roughness, hardness, thickness and friction could be correlated with high film-to-substrate adhesion (L c2 ) for the gradient layer.
