The effect of graphite--epoxy composites on the galvanic corrosion of aerospace alloys. Final report, 1 Jan 1975--1 Apr 1976. [Be-Cu]

Technical Report ·
OSTI ID:7213433
The galvanic corrosion rates of selected aerospace alloys coupled to graphite-epoxy composite materials (GECM) in aerated neutral (pH7) 3.5% NaCl at 22+1 C have been studied. Galvanic current was measured by the use of a potentiostat modified to operate as a zero-resistance ammeter (ZRA). Weight-loss tests were also conducted. Four types of GECM were used along with pure graphite. Twenty-three alloys, including steels, stainless steels, aluminum, beryllium-copper, nickel-base, and titanium alloys, were tested for galvanic compatibility with GECM.
