“…The location of G peak for the Raman spectra is consistent with current literature which is between 1580 cm –1 and 1590 cm –1 for graphene . A 2D peak is vital for graphene determination because it is characteristic of graphene due to the involvement of phonons near the K point which is due to the interaction of two valance bands touching at zone corners and is revealed in the Raman spectra at location ˜2675 cm –1 .…”

As the demand to weld higher strength materials through friction stir welding (FSW) increases, the need for better non‐consumable rotating tool also increases as it has to be able to endure high frictional and thermal deformation while the work‐piece undergoes intense plastic deformation at high temperatures. Carbon‐based nanomaterials are good options to increase strength of steel. An attempt to improve the friction stir welding tool through carbon‐based coatings on H13 tool steel has been carried out. This paper highlights the characterization of the carbon‐based coatings in regard to selected coating parameters through Field emission scanning electron microscope, energy dispersive spectroscopy, Raman Spectra, and X‐Ray photoelectron spectroscopy techniques. The analysis shows presence of graphite like structures whereas Carbon Nanotubes (CNT) was observed to be grown uniformly on the surface.

“…Over the last few years it has been suggested to use graphene (G) as a barrier coating to protect metals from oxidation and, more generally, corrosion12345. Defect-free graphene is highly impermeable to liquids and gases and inert to most chemicals6.…”

Applying protective or barrier layers to isolate a target item from the environment is a common approach to prevent or delay its degradation. The impermeability of two-dimensional materials such as graphene and hexagonal boron nitride (hBN) has generated a great deal of interest in corrosion and material science. Owing to their different electronic properties (graphene is a semimetal, whereas hBN is a wide-bandgap insulator), their protection behaviour is distinctly different. Here we investigate the performance of graphene and hBN as barrier coatings applied on copper substrates through a real-time study in two different oxidative conditions. Our findings show that the evolution of the copper oxidation is remarkably different for the two coating materials.

“…8 On the other hand, concerning the applications, this system has been used as a test-bed for evaluating the performance of graphene-based protective coatings. 9,10,11,12 Moreover, Gr/Ni is of great interest in energy applications. In this respect, density functional theory calculations have recently shown that the H 2 evolution reaction (HER) rate of Gr-coated Ni is significantly higher than that of bare Ni, and comparable to that of Pt.…”

Systems comprising single and multilayer graphene deposited on metals and immersed in acid environments have been investigated, with the aim of elucidating the mechanisms involved, for instance, in hydrogen production or metal protection from corrosion. In this work, a relevant system, namely chemical vapor deposited (CVD) multilayer graphene/Ni (MLGr/Ni), is studied when immersed in a diluted sulfuric electrolyte. The MLGr/Ni electrochemical and morphological properties are studied in situ and interpreted in light of the highly oriented pyrolytic graphite (HOPG) electrode behavior, when immersed in the same electrolyte. Following this interpretative framework, the dominant role of the Ni substrate in hydrogen production is clarified.
