NAB alloy is used extensively in marine applications because it resists marine micro and macrofouling as a result of its copper content. This alloy also combines high mechanical strength and low corrosion rates under turbulent conditions. This alloy consists of a complex microstructure and in recent investigations
the chemistry and crystallography of its phases have been characterized. The rates of selective corrosion of the different phases were found to be influenced by their volume fraction, morphology and distribution
. The selective corrosion was enhanced by erosion and cavitation conditions imposed on this alloy
. Therefore, this investigation aimed at characterizing the role played by each phase present in NAB alloy during cavitation.
