Raman Analysis of CVD Graphene Growth on Cast Iron Piston Ring

Abstract
This study was performed to investigate the feasibility to synthesise graphene on cast iron piston ring using renewable resources via chemical vapor deposition (CVD) method. The selected renewable resources were oil palm fiber (OPF) and polystyrene (PS). The pyrolysis rate of OPF and PS were studied using thermogravimetric analysis (TGA). The coated piston ring was observed under Raman spectroscopy. The results revealed that OPF had a higher pyrolysis rate than PS, resulting in a high-quality and homogeneous graphene oxide coating.
