“…However, the aim of the study was to develop corrosion-resistant coatings working under soft erosive conditions. As such, we also looked for superior mechanical properties of the coating, which are related to the various ratios of hardness to reduced elastic modulus [72][73][74]. It has been reported that H/E r is related to wear resistance, H 2 /E r to the coating's resilience, and H 3 /E r 2 to plastic deformation resistance, thus it can also predict erosion resistance.…”

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.

“…The improvement of corrosion performance could be attributed to the denser structure, as shown in Figure 4, which could effectively limit the diffusion paths of the corrosive medium. This Cr-Al-Si-N coating could be a promising candidate for application in high-temperature wear, oxidation and corrosion [53,54]. …”

Microstructure, Mechanical, Oxidation and Corrosion Properties of the Cr-Al-Si-N Coatings Deposited by a Hybrid Sputtering System

et al. 2017

CrN and Cr-Al-Si-N coatings were deposited on SUS304 and Si-wafers by a hybrid coating system. The Cr and Al-Si target were connected to the cathode arc ion plating (AIP) and high power impulse magnetron sputtering (HiPIMS), respectively. Various Al and Si contents in the coatings were obtained by changing the power of Al-Si target from 0 to 1 kW. The results demonstrated a face-centered cubic structure in all of the coatings. With increasing Al-Si target power, both the density and mean diameter of the macroparticles on the coating surface declined. As Al and Si contents increased, the microstructure of the Cr-Al-Si-N coatings evolved from a dense column structure, to a finer grain column structure, and then to a compact granular-like structure. The hardness of the coatings increased from 21.5 GPa for the pure CrN coating, to a maximum value of~27 GPa for the Cr-Al-Si-N coating deposited at 0.4 kW, which was mainly attributed to the solid solution strengthening and increased residual stress. The addition of Al and Si contents led to enhanced wear resistance against alumina balls at both room and elevated temperatures. Meanwhile, the Cr-Al-Si-N coatings also exhibited an excellent resistance to high-temperature oxidation at 800 and 1000 • C, and improved corrosion resistance, as compared with CrN coatings.

“…The chromium films represent an important and multifunctional material in the various contemporary branches of industry owing to their exceptional properties (enhanced mechanical, corrosion, conductive, optical and catalytic properties) [ 1 , 2 , 3 ]. The chromium thin films (thick up to 200 nm) are widely applied as durable conductive coatings and contact pads in microelectronics and sensors [ 4 , 5 ].…”

“…Earlier, CrSi 2 layers were mainly applied as the barriers of Schottky diodes [ 3 , 4 , 5 , 11 , 14 , 15 ]. At present, the CrSi 2 layers are also used as a joint between silicon and the working element in the integrated circuits and the sensors owing to the low transient resistance and the semiconductor properties [ 2 , 11 ]. This peculiarity in combination with a good compatibility with the regular silicon technologies makes it possible to successfully apply CrSi 2 in the thermoelectric and photoelectric devices [ 1 , 2 , 16 ].…”

The changes in the morphology and the electrophysical properties of the Cr/n-Si (111) structure depending on the rapid thermal treatment were considered in this study. The chromium films of about 30 nm thickness were deposited via magnetron sputtering. The rapid thermal treatment was performed by the irradiation of the substrate’s back side with the incoherent light flux of the quartz halogen lamps in nitrogen medium up to 200–550 °C. The surface morphology was investigated, including the grain size, the roughness parameters and the specific surface energy using atomic force microscopy. The resistivity value of the chromium films on silicon was determined by means of the four-probe method. It was established that at the temperatures of the rapid thermal treatment up to 350 °C one can observe re-crystallization of the chromium films with preservation of the fine grain morphology of the surface, accompanied by a reduction in the grain sizes, specific surface energy and the value of specific resistivity. At the temperatures of the rapid thermal treatment from 400 to 550 °C there originates the diffusion synthesis of the chromium disilicide CrSi2 with the wave-like surface morphology, followed by an increase in the grain sizes, roughness parameters, the specific surface energy and the specific resistivity value.
