How do thermal barrier coatings react to the impact of a foreign object? The authors examined the damage done by a projectile to an air‐plasma‐sprayed coating system. Apart from permanent deformation, chipping of the ceramic top coat around the impression sites occurs at impact velocities above 150 m s–1. At increasing impact speed, the cracks in the top coat tend to elongate and result in coating removal (see Figure for a cross‐section).
