METHOD OF FORMING A COATING OR OF THREE-DIMENSIONAL STRUCTURAL ELEMENTS ON SUBSTRATE SURFACES, WHICH IS/ARE FORMED BY TiAL, BY LASER BUILD-UP WELDING

摘要

The present invention relates to the methods for forming coating or three-dimensional structure element in substrate surface, and the coating or three-dimensional structure element are formed by tial. It is generated by laser overlaying welding. In case of the method according to the invention, with pure or alloy form provide titanium and aluminum steel and/or band, in each case, as the single line or single band within the scope of at least one laser beam impact. Due to heat input, in this case, they are melted and are mutually mixed. As a result, forming the coating or three-dimensional structure element with TiAl on the surface of the substrate.
