Resumo
The application of laser texturing aims to modify the surface without changing its chemical
composition. These alterations can be evaluated through mechanical, physical or chemical
tests. Texturing can be applied to improve efficiency in industrial processes, such as the
flowability of materials, by applying laser texturing to the internal surfaces of components.
This work aims to evaluate the influence of texturing parameters in the flow process of
industrial batchers. UNS S32101 lean duplex stainless steel (LDSS) samples were used for
the tests. For laser texturing of the surfaces, laser of Yb was used, with a wavelength of
1064 nm (infrared), using the scanning speed of 140 mm/s and pulse duration of 150 ns.
Two sets of textured samples were produced: with a frequency of 50 kHz and 2 kHz. In both
frequencys, the power(%) was set at 100, 60 and 20. The effect of texturing was analyzed
through microstructural characterization with tests of contact angle, roughness and
scanning electron microscopy.
