This is the second phase report on sea-water corrosion of materials for use in mechanical seals for submarine shafting and concerns galvanic corrosion effects resulting from combinations of metals and carbon. Six alloys were selected for test a tin bronze, a nickel-aluminum bronze, a high-copper alloy, two nickel-copper alloys, and a nickel-base alloy. Galvanic corrosion was determined for each alloy, coupled to each of three grades of carbon. Results show substantial galvanic corrosion of five alloys. The exception was the nickel-base alloy, which exhibited essentially no attack in either coupled or uncoupled tests.
