    摘要: Method of preparing a metal oxide layer on a substrate, in which the following successive steps are carried out: a) a metal oxide powder is dispersed in a liquid medium comprising a dispersion solvent and a dispersant, the said liquid medium containing neither plasticizer nor binder, by means of which a suspension A of the said metal oxide powder in the said liquid medium is obtained; b) a solution of at least one polymer in a solvent is added to the said suspension A, by means of which a suspension B is obtained; c) suspension B is deposited on the substrate by a dip coating method, by means of which a green layer is obtained; d) the green layer obtained in step c) is dried; and e) the dried layer obtained in step d) is calcined.

    摘要: 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.
