This paper investigates the effect of laser post-treatment on cladded coatings deposited by different thermal spray methods. A wide range of coatings, including a VPS sprayed alloy, three APS sprayed oxide ceramics, and two composites, are treated with either a CO2 or pulsed Nd:YAG high-power laser. The microstructure and wear resistance of the layers are examined before and after treatment and the interaction between the laser and material is modeled using Fusion-2D. Paper includes a German-language abstract.
