The tribological effect of a reduced graphene oxide (rGO)-coated engine cylinder liner by electrophoretic deposition (EPD) process is compared with the chromium carbon nitride (CrCN), titanium nitride (TiN) and diamond-like carbon (DLC) coatings on the cylinder bore using the physical vapor deposition (PVD) process for low friction, better lubricity and high wear resistance. Their tribological performance was evaluated through a reciprocating tribometer, using a steel ball (100CR6) on rGO-, CrCN-, TiN- and DLC-coated diesel engine cylinder liners with 5W-40 engine oil to investigate their wear and friction behavior in the boundary lubrication regime. Tribotests showed less friction in 4 mn of EPD coating of rGO related to CrCN, TiN and DLC coatings. One of the main reasons is that the hardness of rGO coating is less than CrCN, TiN and DLC coatings.
