Abstract (en)
[origin: EP2309024A2] A process by which a ceramic coating (14) is entirely formed from a colloidal-based process to have a thickness that would ordinarily be prone to cracks and spallation involves forming a precursor primer layer on a surface region (12,16,18), and then forming at least a precursor coating layer on the precursor primer layer that is thicker than the precursor primer layer. The precursor primer layer contains particles and a precursor of a first ceramic material. The precursor coating layer contains particles and a precursor of a second ceramic material having the same predominant constituent as the first ceramic material. The precursor primer layer and precursor coating layer are then heated to form a ceramic film (20) and a ceramic coating layer (14), respectively, which consist essentially of the particles and matrices of, respectively, the first and second ceramic materials.
