The quantitative effects of sea water velocity on the cathodic protection of aluminum alloy 5086 are studies in this thesis. At velocities from 0 to 3 knots, two types of tests were conducted: cathodic polarization curves, and 2) current density versus time. The results indicate that increasing the velocity of sea water past this alloy affects its polarization characteristics in two ways, the open circuit potential becomes more negative, and the current density required to maintain a given potential increases. Limited data indicate that a shift of -100 mV from the open circuit potential appears to be an adequate criterion for the cathodic protection of this alloy.
