Abstract

Copper for electrotechnical applications and tin bronzes, which are used in mechanical engineering, were chosen for alloying, respectively remelting experiments. The surface treatment was carried out on ground samples which have not been coated for better absorption. A pulsed 450 W Nd:YAG laser with rectangular beam profile was used. The alloying operation has been performed either as a one step process or in remelting preplaced filter materials. Investigations about the formed microstructure and the resulting hardness have been carried out. The possibility to alloy copper surfaces to higher depths, and the influence of different alloying elements are discussed.
