Abstract

The study focuses on the impact of graphene nanoparticles (GNPs) on the slurry erosion resistance of Mo2C and Co–Ni-based coatings applied to SS304 steel using High-Velocity Oxy-Fuel (HVOF) spraying. The research highlights the synergistic benefits of combining GNPs with Mo2C and Co–Ni to enhance the erosion resistance of hydropower plant components. The article presents a detailed experimental procedure, including the preparation of coatings, slurry erosion testing, and mechanical characterization. The results demonstrate that the addition of GNPs significantly improves the coating's hardness, adhesion, and overall resistance to slurry erosion. The study concludes that tailored coatings incorporating GNPs hold promise for improving the durability and performance of hydropower plant components exposed to harsh erosive conditions.
