摘要：

In this work, we investigated the surface roughness parameters for AlSi10 Mg samples produced by using selective laser melting technology in nitrogen and argon atmospheres. Studies were performed on the up-skin and down-skin surfaces of samples that were produced at different inclination angles with respect to the build platform. Scanning laser microscopy was used to evaluate the surface morphology and the roughness profiles. Typical dependences of the Ra and Rz parameters on the sample’s inclination angles were observed. It is shown that the influence of the build atmosphere is mostly related to an increase in the Rz roughness parameter (to the maximum highest roughness level) at the down-skin sides of the samples by 20%–30% in argon atmosphere, while the Ra parameter remains almost the same for both gases. © 2022.
