Laser beam sintering of coatings and structures

H. Exner, A.-M. Reinecke, P. Regenfuß, M. Nieher, R. Ebert, S. Klötzer


Several novel techniques of ceramics sintering by laser beam have been tested successfully. Compact bodies as well as coatings of alumina were treated with CO2- and Nd: YAG- laser beam. AlN was processed with an argon ion laser. The general difference between these procedures and conventional furnace sintering are the fastness and selectivity of the laser methods. The results are presented together with a consideration of the advantages, limitations and possible applications. They verify the principle applicability of lasers for the sintering of ceramics and reveal insight into the mechanisms of the process.
