“…Such behavior likely reflects the surface effects, such as surface roughness and surface oxides, on the mechanical behavior of materials. This makes it difficult to accurately measure and estimate the contact area [51,52]. From Fig.…”

In this study, simulation and experimental methods were used to investigate the influence of cold spray conditions on AISI 316L stainless steel coatings. The effect of both helium and nitrogen gases used was investigated. The temperature, particle sizes of spraying powder, and distance from the nozzle throat to the impinging point were estimated by using the Kinetics Spray Solutions GmbH software. The 316L stainless steel (SS) coatings were examined by X-ray diffraction, Scanning Electron Microscopy and Energy Dispersive X-Ray Microanalysis. The tribological behavior was evaluated under different loads (2 N and 5 N) in dry conditions. It was found that the nitrogen and helium propellant gas with high speed and fine particles led to produce good coatings with dense microstructures. From the nanoindentation experiments, the Young's modulus and hardness of the SS 316L samples were enhanced of about 8% with helium due to the high particle velocity. It was shown that the wear resistance of SS 316L produced with helium was higher than that of the standard SS 316L coatings. The coatings produced with helium revealed lower friction coefficient (0.65) and wear rate (6.9 × 10–4 mm3/Nm) under 2 N applied load than that obtained nitrogen. It was also found that the SS 316L cold sprayed by helium with dense structure presents high hardness and good tribological performance that can be suggested for several applications.

“…The Lc of the FDC coating was measured to be as large as 38.2 N, demonstrating its good anti-scratching performance and strong adhesion to the metal substrate. It is obviously larger than that of the conventional diamond-like carbon [ 2 , 3 ] and graphite-like carbon deposited by magnetron sputtering, but less than that of its counterpart incorporated with the CrC interlayer [ 5 ]. This indicates the major contribution of the coating/metal interface with a special nano-structure or the chemical covalent bonds to the scratch resistance of the coating.…”

“…Due to its excellent chemical inertness, high thermal stability, environmental friendliness, and cost effectiveness, carbon-based coating has been investigated as one type of the most important surface protection materials. Various carbon coatings have been developed so far, including the conventional diamond-like carbon [ 1 , 2 , 3 ] and graphite-like carbon [ 4 , 5 , 6 ] coatings. As a two-dimensional (2D) carbonaceous material composed of sp 2 -hybridized carbon atoms, graphene is impermeable to most small molecules and possesses exceptional chemical/thermal stability, which makes it a promising protective barrier for the underlying substrate.…”

On the Distinctive Hardness, Anti-Corrosion Properties and Mechanisms of Flame-Deposited Carbon Coating with a Hierarchical Structure in Contrast to a Graphene Layer via Chemical Vapor Deposition

Two carbonaceous (amorphous carbon and graphene) coatings were catalytically grown on bulk Ni plates. It was found that the flame-deposited carbon (FDC) layers exhibited a unique hierarchical structure with the formation of FDC/Ni nano-interlocking interface. The effect of the flame coating time on its corrosion protective efficiency (PE) was studied and compared with that of graphene coating produced via chemical vapor deposition. The FDC grown for 10 min exhibited a PE of 92.7%, which was much greater than that of the graphene coating (75.6%). The anti-corrosive mechanisms of both coatings were revealed and compared. For graphene coatings, the higher reaction temperature than that for FDC resulted in large grain boundaries inherent in the coating. Such boundaries were weak points and easily initiated grain boundary corrosion. In contrast, corrosion started at only certain local defects in FDC layers, whose unique interface structure likely promoted its PE as well. Moreover, after the coating process, the hardness of FDC-coated Ni remained almost unchanged, in contrast to that of graphene-coated samples (reduced by ~30%). This is suggested to be related to the crystal structure evolution of the Ni substrate caused by the heat treatment accompanying the coating process.

“…Furthermore, DLC films can improve stainless steel's corrosion resistance and biocompatibility, which is especially valuable for medical implants and devices. Electrochemical corrosion tests were conducted to evaluate the corrosion resistance of DLC films on 316L stainless steel, and the results showed that the DLC film demonstrated superior resistance to pit corrosion when compared to the 316L substrate in 3.5 % NaCl solution [13].…”

Stainless steel 316L is commonly used in biomedical applications like dental implants, surgical tools, and other devices due to its corrosion resistance and cost-effective materials compared to other biomaterials. It must be enhanced since 316L SS has a relatively low hardness and wear resistance. The coating process includes applying functional materials to the surface to modify and give it the desired properties. This study used a PVD technique for coating diamond-like carbon (DLC) on the surface of 316L stainless steel to enhance its material surface properties. The coated and uncoated SS316 surfaces were exposed to nanoindentation (ultra-nano hardness tester (UNHT3) and electrochemical corrosion tests such as open circuit potential, potentiodynamic polarization, and electrochemical impedance spectroscopy in simulated body fluids at 37 °C. SEM characterized the morphologies and compositions of the surfaces with energy-dispersive X-ray spectroscopy. HIGHLIGHTS DLC coating on SS 316 using Physical Vapor Depositions process was presented The nano indentation was employed for finding mechanical properties of coated and uncoated sample The corrosion behaviors of coated and uncoated sample were performed. The surface topography of SS316 analyzed using SEM GRAPHICAL ABSTRACT
