Abstract: This work presents and discusses the influence of Nd-YAG laser parameters on the texturing of a low laser absorptivity NiCrBSi coating obtained by diode laser cladding. In order to obtain statistical significance, different kinds of design of experiments were considered, choosing a central composite inscribed design as the best according to the number of factors and required runs. In the first stage, a diode laser is used to obtain the NiCrBSi coating and in the second stage an Nd-YAG laser is used to generate surface texturing. Finally, results are observed with a confocal microscope, obtaining diameter and depth of the dimples and statistically studied plotting Pareto charts and response surfaces. The study led to the following conclusions: higher energies and spot diameters generate dimples with larger diameters; low energies and shorter pulse duration involves greater diameters; at high energies diameters remain nearly constant versus pulse duration; at higher energies, shorter pulse durations show greater depths; and at low energies depth remains almost constant versus pulse duration.
