The influence of heat treatments on cavitation erosion resistance of BA1055 alloy

The cavitation erosion is a process of material deterioration as a result of materialization, increase and decrease of the cavitation bubbles in different types of liquid. The cavitation erosion materials are used to prevent the devastating effect of imploding bubbles. The aluminium bronze BA1055 is the most commonly used material among the cooper alloys used on the parts of machines exposed to cavitation erosion phenomenon. The following article brings up the study of the effects of bronze BA1055 heat treatment for its cavitation erosion resistance performed on a flux-impact measuring device. The conducted studies confirmed the extension of the incubation process of BA1055 alloy after the hardening in relation to the moulded alloy. It has resulted in the increase of the resistance to cavitation erosion.
