Abstract
Numerous work pieces, especially shaping tools, suffer from local peak stresses which results in increased wear. Locally remelting insular parts of said work pieces and/or inserting thermal implants (5) of additional materials (7) serves to improve the performance characteristics of the work pieces (1). The material gradients generated thereby permit the construction of tribological systems which are characterized by a self-forming effect. Said effect substantially increases the service life of tools and the like. Preferably, an ND:YAG laser is used in the methods for the thermal treatment of the work pieces.
