Abstract

The invention relates to a method of forming a coating or of three-dimensional structural elements on substrate surfaces which is/are formed by TiAl. Said coating/Said three-dimensional structural elements is/are manufactured by laser build-up welding. The procedure is followed in the method in accordance with the invention that titanium and aluminum are supplied into the region of influence of at least one laser beam in wire and/or band form in a pure or alloyed form in each case as a single wire or a single band. They are melted by the thermal input and in this respect the materials are mixed with one another. The coating or three-dimensional structural elements are thereby formed with TiAl on the substrate surface.
