Abstract Scope |
The present work is focusing on the investigation of dry sliding wear behaviour of electroless NiP-MoS<sub>2</sub>-Gr composite coating on carbon steel substrate. An electroless NiP-MoS<sub>2</sub>-Gr coated carbon steel substrate was characterized using Scanning Electron Microscope [SEM], Energy Dispersive X-Ray Spectroscopy (EDS) and X-Ray Diffractometer (XRD). The surface hardness and roughness were evaluated using a vickers microhardness tester and contact-type surface profilometer. The tribological behaviour of the uncoated and coated substrate was determined at room temperature and high-temperature atmospheric conditions using a pin-on-disc tribometer and the worn surface analysis was carried out using SEM and EDS. A significant decrease in the wear mass loss, coefficient of friction and wear rate of the NiP-MoS<sub>2</sub>-Gr composite coating was observed, this is due to the self-lubrication effect of MoS<sub>2</sub> and graphite particles added to the NiP matrix. The worn surface analysis results revealed that the coating has better adhesion with a substrate surface. |
