Abstract (en)
[origin: WO2022029392A1] The invention relates to a process for coating a substrate using a thermal barrier, comprising at least the following steps: – a step of creating a first roughness on the surface of the substrate by means of at least a chemical or electrochemical attack, the first roughness being characterized by a maximum roughness value Rz1 and an arithmetic mean of the roughness along the profile Ra1; – a step of depositing an undercoat; – a step of creating a second roughness on the surface of the undercoat by means of at least sandblasting or electrochemical attack, the second roughness being characterized by a maximum roughness value Rz2 and an arithmetic mean of the roughness along the profile Ra2, the values Rz2 and Ra2 being smaller than the roughness values Rz1 and Ra1; a step of depositing a thermal barrier by SPS.
