Bronze in seawater

WebNickel-aluminum bronze (NAB) is a metallic alloy that is widely used for ship valves and propellers, among other marine applications. While displaying a good combination of corrosion resistance and strength, NAB is still prone to different forms of corrosion, such as stagnant sea water corrosion, selective phase corrosion, and cavitation erosion. WebSeawater is introduced into the cavity byinsert ing a quartz tube with a small hole in italong the cylindrical axis of the cavity. The volume of the introduced seawater needs to be very small so that perturbation can be theory used for determining the seawater diele ctric constant using the following formulas [10] :
