Erosion behaviour of platinum aluminide bond coat on directionally solidified CM247 and AM1 single crystal superalloys

Thermal barrier coatings system normally consists of substrate, a bond coat and a ceramic top coat. Platinum aluminide diffusion bond coat are extensively used in modern aero-engine. Sometimes bond coat is subjected to solid particle erosion. The objective of present work is to examine the influence...
