OBRABOTKAMETALLOV MATERIAL SCIENCE Vol. 25 No. 1 2023 Fig. 7. The surface of C65500 specimen, printed by the EBAM method, after corrosion tests. Printing modes 1 (a), 2 (b) and 3 (c). Specimen after annealing (d), deformation and subsequent annealing (e) а b c d e a b c Fig. 8. The surface of C65500 specimen with the addition of 10 wt.% Al (a), 10 wt.% Al–5Si (b) and 10 wt.% Al–12Si (c) after corrosion tests All of these results consistently indicate the improved corrosion resistance of the bronze specimens with structures modified due to the use of mechanical and thermal treatments. In turn, the addition of the Al-5Si alloy is the most effective means for modifying the material in order to increase its resistance to electrochemical corrosion.
