Al2O3-13 wt pet TiO2 coating deposited by direct current plasma spray consists of nanostructured region and micro-lamellae. Bend test shows that the ceramic coating can sustain some deformation without sudden failure. The deformation is achieved through the movement of nano-particles in the nanostructured region under tensile stress.
