Abstract (en)

[origin: WO2017080948A1] The invention concerns a multilayer ceramic coating (11) for thermal protection intended to coat a surface of a substrate (10), characterised in that it comprises n consecutive ceramic layers (12, 13), n being an integer greater than or equal to 2, each of the n layers having a columnar, segmented or homogeneous architecture at the micrometre scale and having a finely structured or nanostructured microstructure. The invention also concerns a method for producing such a coating, the method being characterised in that each of the n ceramic layers of the coating is produced by spraying a suspension of submicrometric or nanometric particles by means of a suspension plasma spraying (SPS) method.
