High-Temperature Performance of WC-Co Coatings in Thermal Power Plant Fans: The Role of Cobalt Content on Erosion-Corrosion Resistance

Key Points

• Erosion-corrosion resistance is significantly influenced by cobalt content in WC-Co coatings, impacting performance.
• Samples with higher cobalt content showed better durability under high-temperature conditions than those with lower cobalt.
• Evaluation involved testing coatings in thermal power plant fan conditions to assess their resilience against wear.
• Findings highlight the importance of material composition for enhancing efficiency and reducing maintenance costs.
