ARRANGEMENT AND METHOD FOR CONSTRUCTING A COATING LAYER IN LAYERS

摘要

The invention relates to an arrangement for constructing a coating layer in layers from a highly temperature-resistant superalloy, comprising a substrate (3). A building material (8) which contains the highly temperature-resistant superalloy is deposited on the substrate (3). Multiple individual energy sources which point in the direction of the building material (8) are arranged in an annularly symmetrical manner about at least one energy source which points in the direction of the building material in order to produce a molten bath (7) in the building material (8) section by section. All the energy sources can be controlled separately. The invention further relates to a method for constructing a coating layer in layers.
