Effects of spray power on microstructure and properties of TiC-Ti5Si3-Ti3SiC2-SiC composite coatings prepared by reactive plasma spray

Key Points

• Composite coatings exhibit varied microstructures based on different spray powers, affecting overall properties.
• Microhardness was measured at values up to 20 GPa depending on the spray conditions used during synthesis.
• Analysis was conducted via reactive plasma spray, focusing on the interactions between multiple ceramic phases.
• Findings suggest that optimizing spray power could enhance coating performance, promoting further exploration.
