초록 ▼

In a method for preparing and/or coating the surfaces of metallic hollow structural elements that have at least two connection openings between their outer and inner surfaces, first and second reaction gas mixtures (I, II) are prepared by reaction gas sources for treating the outer and inner surfaces of the hollow structural elements. The first reaction gas mixture (I) is guided over the outer surfaces and thereafter over the inner surfaces of the structural elements, and then the second reaction gas mixture (II) is guided over the inner surfaces and thereafter over the outer surfaces of the structural elements. An apparatus for carrying out the method includes a reaction vessel enclosing an outer reaction space, a central holding pipe arranged in the reaction vessel and enclosing an inner space, and hollow support arms removably attached on the holding pipe to extend radially outwardly therefrom. Each structural element is mounted on a hollow support arm so that one of the connection openings communicates with the inner space through the hollow support arm and the other one of the connection openings communicates with the outer reaction space.

[ What is claimed is:] [1.] A method of treating inner surfaces and outer surfaces of metallic hollow structural elements, comprising the following steps:a) preparing a first reaction gas mixture;b) flowing said first reaction gas mixture in sequence along said outer surfaces and then along said inner surfaces of said structural elements, and then ceasing said flowing of said first reaction gas mixture;c) preparing a second reaction gas mixture; andd) at a time other than during said step b), flowing said second reaction gas mixture in sequence along said inner surfaces and then along said outer surfaces of said structural elements, and then ceasing said flowing of said second reaction gas mixture.
