Praezisionsbearbeitung mit Festkoerperlasern (Oberflaechenbearbeitung). Teilvorhaben: Erarbeitung von Verfahrensgrundlagen zum Feinbeschichten mittels eines Laserstrahl-Pulverbeschichtungsprozesses Abschlussbericht

Using a Nd:YAG laser for laser beam powder cladding, the coating of steel as the substrate with different metallic hard alloys, cemented carbides and oxide ceramical additions has been studied. Process parameters have been optimized, and wear resistance of the coated materials as a function of process parameters has been determined. Nd:YAG laser cladding is especially suited for repair and regeneration of such components, which cannot be treated by other methods on account of the heat exposure. The compiled technical regulation on the Nd:YAG laser cladding supports the practical application of the scientific results from this study.
