The Navy is presently interested in the effect of sea water velocity on typical marine materials such as aluminum alloys, titanium alloys, iron-base alloys, and nickel based alloys. This Navy interest is based on the desire to develop a 100-knot Navy in the near future using high performance ship concepts, for instance, hydrofoils and surface effect ships. A program has been conducted in high velocity sea water to determine the corrosion rates of proposed surface effect ship hull alloys (aluminum alloys) and appendage materials (titanium alloys, stainless steels and high nickel alloys) in sea water at velocities to 90 knots. The general corrosion rates and the galvanic corrosion rates when appendage materials were electrically coupled to the hull alloys were established during the course of this program.
