    Abstract: The invention relates to a method for manufacturing a thermal barrier protection covering a superalloy metal substrate and comprising at least one metal sublayer (13) and a ceramic layer (14) based on zirconia stabilized with yttrium having a column structure defining pores.The following steps are applied: impregnation of a portion of the pores of the ceramic layer (14) with a sol based on zirconia is achieved via a sol-gel route and this in order to form an anchoring sublayer (22), on said ceramic layer topped with said anchoring sub-layer (22), a continuous protective layer (20) based on oxide, is formed via a sol-gel route, and a heat treatment is carried out, whereby an outer protection layer is formed against the attack of the thermal barrier (11) by CMASes. Application to the protection of aeronautical protection parts.

    Abstract: A method for manufacturing a high ductility Ti-, Ti-alloy or NiTi-foam, meaning a compression strain higher than 10%, includes: preparing a powder suspension of a Ti-, NiTi- or Ti-alloy powder, bringing the said powder suspension into a desired form by gelcasting to form a green artifact. The method also includes a calcination step wherein the green artifact is calcined, and sintering the artifact. The calcination step includes a slow heating step wherein said green artifact is heated at a rate lower or equal to 20° C./hour to a temperature between 400° C. and 600° C. and the Ti-, NiTi- or Ti-alloy powder has a particle size less than 100 μm. A high ductility Ti-, Ti-alloy or NiTi foam, with a compression higher than 10%, with a theoretical density less than 30%, pore size (cell size) between 50 to 1000 μm can be obtained with such a method.
