“…In the current study, we report on the electrochemical behaviour of Cr nitride and oxynitride coatings deposited on 304 SS substrates by CAE technique, as there is abundant scientific literature about the use of Cr-based coatings in severe environments, due to their superior corrosion resistance [45,[48][49][50][51][52][53][54]. The corrosion tests of the plain and coated SS were carried out in saline solution by potentiodynamic polarization technique.…”

Chromium nitride and oxynitride coatings were deposited as monolayers ((Cr-N), Cr(N,O)) and bilayers (Cr-N/Cr(N,O), Cr(N,O)/Cr-N) on 304 steel substrates by reactive cathodic arc method. The coatings were characterised by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDS), surface profilometry, and scratch tester. The anticorrosive properties of the coatings were assessed by electrochemical tests in 0.10 M NaCl + 1.96 M H 2 O 2 , carried out at 24 • C. Cr 2 N, CrN, and Cr(N,O) phases were identified in the coatings by grazing incidence X-ray diffraction (GI-XRD) measurements. The measured adhesion values ranged from 19 N to 35 N, the highest value being obtained for the bilayer with Cr(N,O) on top. Electrochemical tests showed that Cr(N,O) presence in both mono-and bilayered coatings determined the lowest damage in corrosive solution, as compared to the Cr-N coatings. This improvement was ascribed to the more compact structure, lower coatings porosity, and smoother surface.

“…To deposit the hard coating, sputtering is normally used from the available processes because of its high deposition rate, thin compound nature with controlled stoichiometry, simplicity and cost-effectiveness compared to the radio frequency (RF) system. Among the various techniques available for the deposition of CrN thin films, reactive magnetron sputtering could be effectively used to tailor the micro structural features of the films [9][10][11][12][13][14][15][16][17]. For some years, chromium nitride coatings have been gaining popularity and becoming important technological materials in the fields of cutting and forming tools, bearing and machine parts, dies and moulds.…”

Chromium Nitride (CrN) thin films are known for their comparatively good mechanical properties. CrN was deposited on Silicon (100) and glass substrates by using DC magnetron sputtering and the influence of the partial nitrogen content and different gaseous environment on their microstructural characteristics were investigated in the present work. The CrN films were characterised with X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM), Atomic Force Microscopy (AFM) and Nanoindentation was used to characterise the structural and mechanical properties of the deposited thin film. The films showed the [200] preferred orientation at lower (at 20%) nitrogen contents while the intensity of the peak [111] increases with the increase in the nitrogen content. The Cr2N (220) peak was identified at a nitrogen content above 30%, but for nitrogen content above 40%, the CrN phase was observed in both films deposited on Si(100) and glass substrates. The preferred orientations of the CrN thin films are strongly influenced by the nitrogen content inside the chamber as observed in the present work. The surface roughness and deposition rate were observed in a reducing trend with the increasing N2 content and temperature from 20.31 to 2.71nm and from 30.16 nm/min to 25.66nm/min, respectively. The hardness and modulus of pure N2 films deposited on the Si substrates were evaluated by nanoindentaion testing and indicated 31 GPa and 250 GPa, respectively.

“…Although hardness and toughness are always considered as the contradiction because they are hard to achieve simultaneously, heterogeneous interfaces are gradually introduced into nanomaterials to enhance them both as interfacial engineering rapidly develops. Hence, hard yet tough and exible hard multilayer or nanocomposite coatings formed by nanocrystalline, amorphous materials and their interfaces exhibit excellent friction and wear properties [5,13,40]. Moreover, superhard yet tough coatings are always expected by the precise control of chemical composition and microstructure to achieve the combined improvement of hardness and toughness 12 .…”

“…Moreover, tribocorrosion in seawater environment coupled with negative interactions of wear and corrosion would substantially result in the degradation and failure [2,3]. Surface modi cation and advanced coatings are expected to improve seawater lubrication and durability of components to ultimately obtain high working performance and long service lifetime [4,5]. One of achievable strategies for the enhancement of tribocorrosion performance is nanostructured coatings deposited on surface components for combined improvements of seawater lubrication and anti-corrosion [6][7][8][9][10][11].…”

“…Nevertheless, tribocorrosion resistance of the coatings are highly desired for seawater lubrication and durability by the control of surface integrity and interface structure. It is found that cubic CrN coatings deposited on stainless steels using plasma immersion ion implantation showed the enhanced wear and corrosion resistance [5]. However, micro-cracks induced by friction resulted in multi-degradation of the coatings with a typical columnar growth structure, such as intersecting cracks and layer delamination.…”

Cubic transition-metal nitride coatings have been regarded as promising candidates for of marine engineering components in seawater environments. However, the excellent seawater lubrication is hard to achieve due to contradictory relations of hardness and toughness, as well as unstable behaviors at sliding contact surface. As discussed in our previous work about the enhanced tribological behaviors of hard yet tough CrN/Si3N4 multilayer coatings[14], superhard yet tough coatings are highly desired to improve wear resistance and durability in aggressive solutions. Here we report Ti-C-N coatings with Ti(C,N) and small sp2-C phases deposited by high power impulse magnetron sputtering exhibit simultaneously superhardness of 40.2 GPa and favourable toughness (without radial cracks in HRC indentations). Superhard yet tough Ti-C-N coatings show excellent seawater-lubricating behaviors with extremely low friction coefficient of 0.03 and smooth wear morphologies in 3.5wt.% NaCl aqueous solution. The enhanced tribocorrosion performance are attributed to superhard yet tough properties resulting in the increased resistance of crack initiation and propagation, which restrains synergistic actions of wear and pitting corrosion. In addition, stable self-lubricating amorphous carbon phase at sliding contact surface reduce friction and wear in seawater.
