SEM micrographs of surface morphologies of L-PBF specimens after immersion in 8 mol/L HNO₃ at boiling temperature for 240 h. Different process parameters are represented: (a) laser power of 80 W (V_m  = 61 ± 2 μm/year), (b) shows the attack of equiaxed cells when a laser power of 80W was applied, (c) scanning strategy without rotation (V_m  = 54 ± 6 μm/year), (d) HD of 30 μm (V_m  = 125 ± 22 μm/year). The white arrows highlighting the presence of pores on the surface.
