摘要

Surface texturing is an established method for altering the structure of a surface. All known methods deal with material removal. For applications where only small walls remain on the surface, this means that most of the surface must be treated. In this paper, a new approach is presented in which texturing and laser cladding are combined in a single-step buildup process. Since only small selected areas are built up, instead of removing large areas, optimization of the processing time is expected. A galvanometer scanner and a lateral flat-bed powder nozzle are used. First results showed proof of the principle. Cladding thicknesses of more than 100 μm can be generated for small structures as well as for large areas.
