Understanding the thermal cyclic performance of thermal barrier coatings with laser-textured bond coats

Key Points

• The thermal cyclic performance was enhanced in coatings with laser-textured bond coats, demonstrating greater resilience.
• Key metrics indicated that laser-textured bond coats maintained structural integrity across multiple thermal cycles.
• Observational analysis reveals that surface texture significantly affects the performance of thermal barrier coatings under cyclic stress.
• Highlights the potential for laser-texturing to improve the durability of thermal barriers in extreme environments.
