Effect of hydrogen on graphene growth from solid waste products by chemical vapour deposition: friction coefficient properties

Purpose The purpose of this paper is to study the effect of hydrogen (H2) gas on the graphene growth from fruit cover plastic waste (FCPW) and oil palm fibre (OPF), as a solid feedstock, towards the coefficient of friction (COF) properties. Design/methodology/approach Graphene film growth on copper (Cu) substrate was synthesised from FCPW and OPF, as a solid feedstock, using the chemical vapour deposition (CVD) method, at atmospheric pressure. The synthesised graphene was characterised using Raman spectroscopy, Scanning Electron Microscopy (SEM) and Electron Dispersed Spectroscopy (EDS). Surface hardness and roughness were measured using a nano-indenter and surface profilometer, respectively. Then, a dry sliding test was executed using a ball-on-disc tribometer at constant speed, sliding distance and load, with coated and uncoated copper sheet as the counter surface. Findings The presence of H2 gas reduced the running-in time of the dry sliding test. However, there is no significant effect at the constant COF region, where the graphene growth from FCPW shows the lowest COF among other surfaces. Research limitations/implications This paper is limited to graphene growth using the CVD method with selected parameters. Originality/value To the authors’ knowledge, this is the first paper on growing graphene from palm oil fiber via the CVD method and its subsequent analysis, based on friction coefficient properties.

Cvd Method

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.

Vs Mechanism

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.
