Characterization of High-Velocity Oxygen Fuel and Shrouded Plasma Sprayed Cr3C2-CoNiCrAlY Coatings: Feedstock, As-Sprayed, and Equilibrium Heat-Treated Coatings
Abstract This research examines the combination of a corrosion-resistant CoNiCrAlY binder with Cr3C2 carbide particles. The powder was applied using two contrasting thermal conditions: low-energy HVOF and high-energy shrouded plasma spraying. This approach created a wide range of carbide dissolution and peritectic decomposition outcomes. The study includes detailed characterization of the feedstock powder composition to explain the phase formation during sintering compared to the original powder components.
