Abstract: The invention relates to a high-pressure line for conveying a fluid under high pressure to a consumer, in particular for supplying fuel under injection pressure to one or more injectors (14) of a combustion engine. It comprises a first (1), a second (2), and a third line section (3), which line sections (1, 2, 3) are flowed through successively in the intended operation of the high-pressure line and are jointly formed by a ones-piece component (4) made of metal, wherein the first line section (1) and the third line section (3) each have a smaller flow cross-section than the second line section (2) arranged between them.

Abstract: A process for producing a spatially shaped carrier layer (3) which is of foil-like design from hard brittle material includes: providing a basic mold (1) having a spatially shaped surface, depositing a material which is in the gas or liquid phase on the spatially shaped surface, solidifying the material which has been deposited on the spatially shaped surface to form a hard brittle material layer (3), and separating the hard brittle material layer (3) from the spatially shaped surface in order to obtain the carrier layer (3) which consists of hard brittle material.

Abstract: The invention describes a temperature-stable protective coating over a metallic substrate surface (1), which coating includes at least one layer of material (4) consisting of MCrAlY, where M represents at least one of the elements selected from the group of materials consisting of Fe, Co and Ni. The invention also describes a production process for this coating.
