Abstract: In this study, WC10Co4Cr (particle size 45±15 μm) and WC10Co4Cr+Graphen nano-platelets (GNPs) of particle size 15±10 μm cermet coatings were deposited on an ASTM A479 steel substrate utilising the High-Velocity Oxygen Fuel (HVOF) technique. The wear and corrosion of coated and uncoated surfaces were studied using the pin-on-disc and salt spray testing methods, respectively, and the micro-hardness of the cross-sections was tested using a Vickers micro-hardness testing machine at an applied force of 10N. Further, surface morphology of coated and uncoated substrate was investigated using scanning electron microscopy (SEM) and microscopic images. The analysis revealed that WC-10Co-4Cr+GNPs-coated (C2) surfaces outperformed WC10Co4Cr coated (C1) surfaces in terms of wear resistance.
