In this thesis, an analysis of the chemical composition and microstructure was carried out, in addition, the mechanical properties of the overlay of aluminum bronze mark CuAl8Ni2Fe2Mn2 on the base material CuAl10FeNi5 were tested. In the theoretical part of the thesis, copper and its alloys are described, and special attention is paid to bronzes and their applications. In the experimental part of the thesis, the chemical composition of the base material and overlay metal was examined and proved to match the prescribed chemical compositions. In the microstructure of the base material α-phase, eutectoid and κ-phase precipitates are visible. The melting line is clearly defined, while the heat-affected zone is relatively narrow without irregularities. Overlay metal has a typical foundry dendritic-oriented microstructure without observed irregularities. The highest hardness values were measured in the heat-affected zone, 216 HV0.2 and 220 HV10. The hardness of the base material was 196 HV0.2 and 191 HV10, and a similar value was measured in the first overlay layer, while the hardness in the second and third overlay layers gradually decreases. It was also determined that the base material and overlay metal do not have great bending properties due to the appearance of cracks at small bending angle. After the analysis of the results, the satisfactory quality of the overlay was determined, provided that the area of the overlay is not subjected to bending stress during exploitation.
