Abstract A multilayered unit includes a core comprising an energetic material and an activator; a support layer disposed on the core; and a protective layer disposed on the support layer, wherein the support layer and the protective layer each independently comprises a polymeric material, a metallic material, or a combination comprising at least one of the foregoing, provided that the support layer is compositionally different from the protective layer. The multilayered unit can be embedded in a component, attached to a component, or disposed between two components of a downhole assembly. The downhole assembly containing the multilayered unit has controlled disintegration in a downhole environment. L'invention concerne une unité multicouche comprenant un noyau comprenant un matériau énergétique et un activateur ; une couche de support disposée sur le noyau ; et une couche protectrice disposée sur la couche de support, la couche de support et la couche protectrice comprenant chacune indépendamment un matériau polymère, un matériau métallique, ou une combinaison comprenant au moins l'un des éléments précédents, à condition que la couche de support ait une composition différente de celle de la couche de protection. L'unité multicouche peut être incorporée dans un élément, fixée à un élément, ou disposée entre deux éléments d'un ensemble de fond de trou. L'ensemble de fond de trou contenant l'unité multicouche présente une désintégration commandée dans un environnement de fond de trou.
