    摘要： The quality or durability of an oxidation protective coating produced by alitizing or aluminizing on the surface of a structural component made of titanium or titanium alloy, is improved by adding niobium to the surface of the structural component. The addition may be accomplished prior to the aluminizing or during the aluminizing. Prior application may involve, for example, vapor deposition of the niobium. Simultaneous application involves including a niobium donator powder in the aluminizing powder mixture.

    摘要： A device for coating hollow workpieces made of heat-resistant alloys, such as Ni, Co or Fe base alloy via gas diffusion is provided. The outer and inner surfaces of the workpieces are linked with one another by bores. The workpieces are arranged in a container which is located in a processing chamber. The workpiece holders are arranged at a geodetically low height with respect to a donor metal body. The donor metal body made of granulates, sintered metal or compact metal completely surrounds the outer surfaces of each workpiece to be coated while maintaining a gap. The device is suitable for the inner and outer coating of power unit blades with cooling air bores.

    摘要： A method for the production of a locally limited diffusion layer on a metal component is disclosed. In an embodiment, the method includes the steps of application of a paste containing Cr, Si and/or Al, and containing activators, to the areas of the metal component to be coated. The paste is solidified to form a donor pack. The regions which are not to be coated and are adjacent to the donor pack are covered with a diffusion-blocking powder pack. The component is heated to a temperature above 900° C. in order to carry out the alitation, siliconization and/or chromation. The method can be used in the production of turbine rotors.

    摘要： A process for chroming an inner surface of a component, in which the inner surface which is to be coated is not brought into contact with a powder which forms the coating gas, includes: providing a mixture of chromium granules and an activator; heating the mixture to a temperature at which a coating gas which substantially comprises gaseous CrCl is formed; dissipating the coating gas; and exposing the inner surface of the component to the coating gas thereby forming a chromium-containing diffusion layer.
