Due to the excellent chemical inertness, graphene can be used as an anti-corrosive coating to protect metal surfaces. Here, we report the growth of graphene by using a chemical vapour deposition (CVD) process with ethanol as a carbon source. Surface and structural characterisations of CVD grown films suggest the formation of double-layer graphene. Electrochemical impedance spectroscopy has been used to study the anticorrosion behaviour of the CVD grown graphene layer. The observed corrosion rate of 8.08 × 10−14 m/s for graphene-coated copper is 24 times lower than the value for pure copper which shows the potential of graphene as the anticorrosive layer. Furthermore, we observed no significant changes in anticorrosive behaviour of the graphene coated copper samples stored in ambient environment for more than one year.

The present work mainly focus on the development of a coating material for bearing applications using Chemical Vapour Deposition (CVD) method. The presence of coatings and surface topography play a vital role in the tribological performance of sliding components such as bearing. The coating used should reduce friction as well as wear of the components. An attempt has been made to develop a coating material that is provided on bearings in order to facilitate wear-resisting property improving the bearing properties significantly. Titanium Carbonitride TiCN is an extensively used material on tools used for abrasive cutting and machining operations, but still not used as a coating material in bearing applications. In this direction, (TiCN), an abrasion resistant ceramic coating was formed by adding a small amount of carbon to the Titanium Nitride (TiN) and the developed coating was applied on the bearings in the form of a thin film of 3 μm thickness. The carbon makes the coating harder and thereby provides a lower friction coefficient. Specimens were developed as per ASTM standards with size 10 x 10 x 20mm with and without coating material. The coated specimens were tested on Pin-on-disc wear testing machine and a comparative study between the TiCN coated bearing and the conventional bearing was carried out in terms of wear rates determination. SEM and EDAX analysis was also carried out for the tested specimens to ensure proper distribution of carbon in TiN. From the study it was found that the coated material showed lesser wear rate by 21% when compared to the conventional uncoated specimen and SEM showed proper bonding between the carbon and TiN.

Multiwall carbon nanotube (MWCNT) and alumina hybrid compound prepared via chemical vapour deposition (CVD). The CVD process always reported that the catalyst must undergo calcinations and reduction process before growing the carbon nanotube (CNT). In this work, MWCNT-alumina hybrid was successfully synthesized via simple CVD method. The morphologies study showed that the MWCNT-alumina hybrid with calcination and reduction, and calcination without reduction has been successfully synthesized.

Zinc oxides nanowires (ZnO NWs) were successfully synthesized on bare silicon substrates using Chemical vapour deposition (CVD) method without foreign catalyst. The ZnO NWs had good crystal quality as they exhibited a strong UV emission (373 nm) corresponding to the free exciton emission and a weak green arising from defect-related emission in PL measurement. Measurement of low temperature photoluminescence spectra show a peak of free exciton and defect bound excitons. The growth of these catalyst-free ZnO NWs was governed by Vapour-Solid (VS) mechanism.

Abstract This paper presents a comparison of chemical and plasma electrolyte polishing methods for preparing a copper substrate for graphene synthesis by chemical vapour deposition. It is shown that in order to achieve the most uniform morphology of the surface of the copper substrate, it is preferable to use the electrolyte-plasma polishing method. With its help, the proportion of multilayer regions in the graphene coating obtained as a result of CVD synthesis decreases. The obtained results may serve a recommendation for creating a graphene coating with specified parameters.
