OBRABOTKAMETALLOV MATERIAL SCIENCE Vol. 27 No. 3 2025 Fig. 9. Elemental mapping of oxygen on the wear track surfaces of Cu-Al-Si-Mn bronze. Sample 1 (a), sample 2 (b), sample 3 (c), sample 4 (d) and sample 5 (e) a b c d e action during sliding friction. During friction, these layers were disrupted by repeated mechanical action from the counterbody. Three-dimensional surface scanning provided detailed data on the morphology of the wear track crosssections, as shown in Fig. 10. The profile shape of each track closely mirrored the spherical configuration of the steel balls used, without any noticeable deviations. Furthermore, the track profiles clearly visualized characteristic surface microroughness formed during frictional interaction and subsequent wear of the material. Quantification of wear, achieved through accurate determination of the cross-sectional area of the obtained profiles, revealed a significant disparity in the wear resistance of the samples. Specifically, printed a b Fig. 10. Cross-sectional profiles (a) and areas (b) of the wear tracks of Cu-Al-Si-Mn bronze
