A small segment of the specimens is selected for the corrosion test, perpendicular to the stir zone with dimensions of 10 × 10 × 6 𝑚𝑚 3 . Before the test, the samples are polished with sandpaper and degreased with acetone. After washing with distilled water, except on the intended surface, the rest are covered with varnish. Then, to quantify the samples' response to corrosion, a corrosion test is performed with 60 minutes of immersion time in 3.5 weight percent NaCl solution (pH = 7)
