    Improvement in surface integrity of CuAl8Fe3 bronze via diamond burnishing

  • Original language description

    The single-phase CuAl8Fe3 aluminum bronzes possess good strength and resistance to fatigue as well as high corrosion and wear resistance. Since this alloy contains less than 8.5% aluminum, it cannot be heat treated. Therefore, improvements in surface integrity (SI) can only be achieved via mechanical surface treatment. This article investigates the influence of the basic diamond burnishing (DB) process, as well as additional factors, on the SI characteristics of CuAl8Fe3 bronze. Using experiments and regression analyses, a multi-objective optimization of the DB process has been accomplished via non-dominated sorting genetic algorithm (NSGA-II) and optimal values of the factors have been established. Using these factor values, the SI characteristics of diamond-burnished CuAl8Fe3 specimens have been quantified. The conclusion has been reached that the DB of CuAl8Fe3 bronze can be implemented as mixed burnishing, i.e., DB results in a favorable combination of the height and shape parameters for the surface texture, very low roughness (nearly mirror surfaces), large (in absolute value) residual hoop and axial stresses at depths greater than 0.8 mm, high surface micro-hardness and strongly expressed grain-refined microstructures at depths of up to 0.15 mm. These SI characteristics suggest a significant increase in fatigue strength and wear resistance of CuAl8Fe3 bronze finished via DB.
